Evil Moon 13: Must-See Newbie Guide – Classless Builds & the Four Core Classes

If you’ve hung around the Undecember community for even a few days, you’ve definitely seen these questions over and over: “Which class is best for newbies to get started with?” “What’s the strongest class right now?” “Warrior, Mage, Bowman, or Summoner— which one burns the least resources?”

At this point, veteran players will usually drop that infuriating but dead-on answer: “This game doesn’t even have actual classes.”

Newbies will be stunned: No classes? Then what do I pick? Isn’t this game just supposed to be like others— pick a “Warrior” to hack and slash, a “Mage” to toss spells, or a “Bowman” to sit back and shoot from afar?

Calm down— this guide is gonna break it down so even a newbie gets it. In Undecember, so-called “classes” are just labels players made up. What actually determines your playstyle is: weapon, skill runes, link runes, Zodiac points, and gear modifiers.

Next, I’ll cover everything from the core concept of the non-class system, to newbie picks, how to think about power rankings, playstyle splits for Warrior/Mage/Bowman/Summoner, rune linking, Zodiac point allocation, leveling routes, endgame gear, late-game progression, and even a FAQ.

I. First, Get Undecember’s “Non-Class System” — What *Is* a “Class” in This Game, Anyway?

A. Why Doesn’t Undecember Use Traditional Fixed Classes?

What makes Undecember stand out most is that unlike most ARPGs, it doesn’t make you pick “Warrior, Mage, Archer” at the start and lock you into that class forever. Instead, it breaks down “classes” into parts— letting players mix and match to make their ideal playstyle.

Think of it like this:
In other games, picking a Mage class means you’re born with Fireball, Ice Arrow, Lightning, and all those spells.
In Undecember? You’re just a “base character.” What weapon you hold, which skill runes you socket, and which link runes you pair— that’s what makes you play like a Mage or a Bowman.

This leads to the first big newbie misconception:
“If I pick the wrong class, I’m stuck.”
But in Undecember, it’s more like: “If I pick bad skills, mess up link runes, or misallocate points early on, I’ll hit a wall.”
Because your build can change, skills can be swapped, and weapons can be replaced— the real waste is spreading your resources too thin early on and missing growth opportunities.
That’s why veteran players keep stressing: don’t hoard too many skills early. Focus on one build that gets you through chapters and clears mobs first.

B. Skill Runes, Link Runes, and Weapons: How to Make Your Own Build

You can break down Undecember’s gameplay into three core parts:

1. Skill Runes = Your Main Attack/Support
   For example, you can use Whirlwind Slash to clear hordes, projectiles to pierce through enemies, DoT poison to chip away at foes, or summons to tank damage.

2. Link Runes = Turning Skills into “Class Flair”
   Same skill, different link runes— totally different playstyles:
   Link it to “Area Increase” → become a map-clearing machine;
   Link it to “Max Single-Target Damage” → go all in on boss fights;
   Link it to “Life Leech, Shield, Damage Reduction” → become unkillable.
   This is Undecember’s coolest part: You’re not passive picking a class— you’re actively “designing your own.”

3. Weapons & Gear Modifiers = Backing Up Your Build
   Bow builds rely heavily on attack speed and projectile-related modifiers; Mages thrive on elemental damage, cast speed, and crit chance; Melee needs survivability, life leech, armor, and face-to-face resilience; Summoners have to choose between dealing damage themselves or letting their minions do all the work.

So if you ask “which class is strongest,” veterans will ask back: “Which build? Map-clearing, bossing, or usable in late-game Chaos Dungeons?” There’s no absolute strongest class— only builds that fit your playstyle.

C. New

When Newbies Ask About "Classes", These Are 3 Things They Actually Need To Know

When newbies keep pestering about class picks, what they really want to figure out is almost always these 3 things:

1. I want to use fewer resources, die less often, and breeze through chapters—are there any super reliable builds that get the job done?

2. I’m bad at this (clumsy af), don’t want builds that require constant dodging—are there simple, no-fuss builds for people who’d rather relax than grind?

I only plan to put in a tiny bit of money, or even none at all—what playstyles let me clear content without relying too much on gear?

Truth is, the actual things you should care about aren’t "class names" at all—they’re these aspects:

• What core skills link together for this build early on?

• What key link runes does it use?

• What main stats does it rely on to boost damage?

• What’s its survival mechanism? The key thing that keeps you from dying instantly?

• Can you respec it into other builds later on in the game?

Once you learn to analyze builds from these angles, you’re already better than half the players who just copy the top-ranked builds blindly.

2. Newbie Class Recommendations for *Thirteen Wicked Moons*

A. The Most Reliable Build Directions for New Starter Areas

For new players in the early game, I only have one core rule: Prioritize consistent clear and reliable farming—don’t chase max damage right out the gate.
In *Thirteen Wicked Moons*, what actually breaks you isn’t not being able to kill enemies—it’s dying way too often, super slow farming speed, never having enough resources, and ending up stuck in a "poorer as you play" cycle.

The most newbie-friendly and reliable build types for starters are roughly these:

• DoT (Damage over Time) Builds: You don’t need to stack super high crit to deal good damage, clear trash mobs easily, and have no lull in attacks when fighting bosses.

• Ranged Projectile Farming Builds: Attack enemies from a safe distance, have extremely high error tolerance, and almost never die suddenly.

• Summon/Follower Builds: Have minions that take hits for you—you just focus on dealing damage and buffing yourself, super newbie-friendly.

• "Sturdy" Melee Builds: For example, if you prioritize survival and use life steal to stay in fights, melee can be comfortable too—but you need to learn positioning and how much damage you can tank earlier on than with ranged builds.

B. Which Class is Easiest to Pick: Warrior, Mage, Archer, or Summoner?

I’ll cut to the chase from actual new player experiences:

• Mage: The top rec for newbies because of smooth clear, safe attack range, and flexible playstyles. You don’t have to play as a fragile glass cannon—you can go DoT, control-focused, or even mixed-element builds.

• Archer: Great farming efficiency, but needs "link runes and gear to align with your build direction." If a projectile build suddenly switches to defense or magic-related stuff, it gets awkward fast.

• Summoner: If you hate getting up close to enemies, hate being swarmed by trash mobs, and want less pressure on bosses, Summoner is super comfy. Con: Some people find it slow-paced, and less satisfying than fighting directly.

• Melee Warrior Builds: Feel great to play, super satisfying—but the biggest newbie frustration with melee is diving into enemy hordes before figuring out survival mechanics like life steal, damage reduction, or armor, then instantly dying.
  It’s not that melee is weak—it’s that you need to learn when to back off and how to use survival mechanics to stay alive first.

So if I had to pick the "easiest to master" builds:
Summoner / Ranged Mage / Ranged Projectile Builds are usually the most low-fuss.

C. What Starter Build Should Free Players & Returning Players Pick?

• Free-to-Play Players: ... (Based on context, you should choose a build that doesn’t rely heavily on expensive gear or rare drops, has consistent farming potential, and lets you progress without paying extra.)

Prioritize Builds that deal consistent damage without relying too much on gear. Simply put: Don't go for playstyles that only shine with high Crit Chance, high Attack Speed, or rare affixes right from the start. Focus on clearing maps, beating content, and farming resources reliably first, then you can adjust your Build later.

Returning Players: Your biggest advantage is already knowing the game system well, so you can plan your transition to your desired endgame Build earlier. I recommend starting with a playstyle that's "safe for leveling and can be converted into the endgame Build you want" — this way you won't get stuck needing to re-level mid-game.

III. Strongest Classes & Playstyle Rankings in UNDECEMBER

I'll use "context-based rankings" here instead of a fixed list, because what counts as "strongest" in UNDECEMBER depends entirely on what you're asking: clearing maps, taking down bosses, or endgame high-tier content.
Picking based on actual scenarios will keep you from being misled by generic rankings.

A. Early-Game Meta Playstyle Recommendations

Playstyles that work well in early game usually have three key traits:

1. Simple Linking Requirements: You won't need to hoard a bunch of rare link runes to make the Build work.

Not Too Picky About Perfect Affixes: You can just pick up any decent gear you find and jump into action, no need to stress about missing specific stats. Low Survival Pressure: Whether you’re playing a ranged damage build, a summoner, or a Build with built-in sustain mechanics, you’ll have a much smoother time in the early game — these are real standouts.

So the fastest, most beginner-friendly and safe strong playstyles in early game are basically these:
DoT (Damage Over Time) builds, projectile builds that keep a safe distance, or summon/semi-summon builds that assist with damage.

B. Mid & Late Game Meta Builds: Map Clearing vs Bossing

Once you hit mid to late game, playstyles start to split clearly:

• Map-Clearing Builds aim for: Large area-of-effect (AoE), fast mob clear speed, high movement efficiency, and reliable life sustain.

• Bossing Builds aim for: High single-target damage, good survival, and consistent, steady sustained damage — not the type where you lose immediately if you don’t nail a perfect skill rotation to one-shot the boss.

Map-clearing meta builds usually have these traits:

• Either their skills cover massive AoE and hit multiple targets at once;

• Or their projectiles have splash, pierce, or bounce effects to hit even more mobs;

• Or they let you cast while moving, so you don’t have to stop to attack.

As for bossing meta builds, they usually have these traits:

• Have link runes or stats that boost single-target damage;

• Have reliable sustain so you don’t get low on HP quickly;

• And they need high "effective damage time" — basically, they can keep dealing damage consistently without dying all the time and interrupting their rotation.

This is when you’ll notice a super common scenario: A lot of builds that are insane for map clearing are terrible for bossing, and vice versa. This is the biggest mid-game roadblock in UNDECEMBER:
"I clear maps super fast, but bossing feels like scraping damage and I die all the time."
Don’t re-level your whole playstyle here — just adjust your link runes, gear, and Zodiac setup to lean towards bossing, and that’ll fix most of your problems.

C. F2P vs High-Resource Playstyle Differences

Playstyles for F2P players usually have these advantages:

• Fast to get going — no need to spend ages farming all the required items;

• Not super picky about perfect affixes — you can play with just decent gear;

• Survival is easier to set up — you won’t die out of nowhere;

• Damage is consistent instead of chasing extreme critical hit damage.

Playstyles that require more resources usually have these traits:

• Insanely high damage cap;

Requires specific rare link runes or extremely rare gear affixes;

Heavily reliant on precise stats like attack speed, critical strike chance, and penetration;

If you can stack these stats, it feels incredibly satisfying to play. But if you can’t get them perfectly aligned, the experience can be rough, even leading to frustrating roadblocks.

So if you’re a free-to-play player or only willing to spend a little, I recommend starting with a budget-friendly build first. While playing, accumulate resources and save up gear and runes. Once your "gear and rune collection" is robust enough, switch to a more investment-heavy build—you’ll have a way better experience then.

IV. Undecember Warrior Build Guide

A. Pros, Cons, and Suitable Players for Melee Builds

The pros of melee builds are pretty straightforward: They feel incredibly satisfying to play, are very tanky, and have an intense up-close combat feel. Especially when you’re clearing packs with Whirlwind or smacking enemies with heavy weapons—the impact feel is something ranged builds can never match.

But the cons of melee builds are equally realistic:

You’re super vulnerable to enemy skill damage;

You need solid survival mechanics to keep you going;

If your gear isn’t up to par, you’ll often get that frustrating feeling of: "I’m hitting so hard, but my HP bar is draining like a sieve."

So who are melee builds for?

Players who love going head-to-head with enemies;

Players willing to take the time to learn survival mechanics;

Players who don’t mind dying a lot early on and are willing to tweak their link runes.

If you’re clumsy and hate dying, you can still play melee—just play more cautiously and put survival stats at the very top of your priority list.

B. Analysis of Popular Melee Builds Like Whirlwind and Ice Hammer

I’ll break down core mechanics so you can easily spot the differences between various melee builds:

Whirlwind-type
Core advantage: Smooth clear speed—you can spin around in a pack of enemies and wipe them all in one go, with a natural, fluid rhythm.
Key things to watch out for: You absolutely must ensure you can survive in enemy packs, so stats like lifesteal, armor, resistance, and health regen need to be sufficiently stacked. The biggest mistake with Whirlwind builds is focusing only on damage and ignoring survival—you’ll die within two seconds of spinning.

Ice Hammer/Heavy Strike-type
These builds usually focus more on dealing massive single-target damage or controlling and locking down enemies with crowd-control effects and debuffs. Their clear speed might not be as "smooth" as Whirlwind, but they’re more consistent against bosses because their attack rhythm is easier to manage.
Common pitfalls for Heavy Strike builds: If your attack speed is low or the feel is off, they’ll feel very clunky to play, so you need to be more deliberate when choosing gear affixes and link runes.

You’ll notice that melee classes have way more in common than just "sticking close to enemies to deal damage." The real core difference is whether you want to go for a sustained damage playstyle or focus on a heavy-hitting, controlled rhythm. Figure out which one you prefer first.

C. Warrior Build Attribute Allocation, Gear, and Skill Link Tips

For melee class attribute allocation, here’s a super versatile tip for new players:

Attributes are your absolute core focus: After all, attribute bonuses directly affect melee weapon requirements, survival ability, and damage output—they’re super important.

Survival is NOT a secondary stat—it’s your main priority first:
When choosing gear affixes, prioritize building a solid base with "resistance, health, armor/damage reduction, lifesteal, or health regen."

Link runes should focus on survivability first, then damage:
The most common mistake new players make is slapping on a bunch of damage-boosting runes right away, only to get oneshot as soon as they step into a pack.
You should first make sure you can "stay standing" before boosting your damage. As long as a melee class can hold their ground, their DPS usually won’t be bad.

V. Undecember Mage Build Guide

A. Why Mage Builds Are Good for New Players’ Early-Game Leveling

Mage builds are great for new players’ early-game leveling because they have three key advantages:

1. Safe Attack Range: No need to get up close and personal to trade blows with enemies, so your mortality rate is way lower!

   Comfortable Clear Range: Most spells come with built-in Area of Effect (AOE) or multi-hit damage, making mobbing super smooth.

   Versatile Skill Link Builds: You can go for a direct damage build, Damage Over Time (DoT) build, or even an elemental hybrid route—tons of room to tweak and customize.

   So once new players get a solid caster build rolling, mapping and farming resources will become way easier. This is super important, especially in the early game when resources are tight.

   B. Playstyle Comparison: Poison Spark, Elemental Mage, and DoT Builds

   • DoT Builds:
     Pros: Doesn’t rely heavily on crits, accessible gear requirements, and super stable for boss fights.
     Cons: Not as instantly satisfying as crit builds (those one-shot kills hit different), it’s more about “steady burning enemies to defeat.”
     Perfect for F2P players, low-spend players, or new players who don’t want to mess with crit math.

   • Elemental Direct Damage Builds:
     Pros: Insane burst damage, super satisfying mob clears.
     Cons: Usually depends on cast speed, crit, damage penetration, or damage boosts. If your gear or skill links aren’t up to par, the damage gap will be noticeable.
     Great for players who love that bursty feel and are willing to invest resources into boosting their damage cap.

   • Hybrid Builds:
     Pros: Good balance between mapping and bossing, no extreme leaning one way.
     Cons: You need to be clear on your core damage source—otherwise you’ll spread yourself too thin and end up with a messy, unoptimized build.

   C. Caster Builds: Skill Points, Rune Combos, and Survival Tips

   New caster players often die not because they can’t deal damage, but because they think staying far away means they won’t get hit. In Evil Moon 13, lots of enemies hurl projectiles, charge at you, and have AoE explosion skills. If you only focus on dealing damage and ignore resistances and positioning, you’ll go down fast.

   The top 3 survival tips for new casters, organized for you:

   1. Resistances Must Be Fully Stacked: If your resistances are low, you’ll feel as fragile as paper—one hit will take a huge chunk of your HP.

   2. Get Used to Moving and Positioning: Don’t stand still casting until the last second to dodge skills!

   3. Save Some Skill Links for Survival: Link your skills with lifesteal, shields, damage reduction, or other survival mechanisms—don’t fill every link slot with damage boosts.

   A lot of mage players don’t lack damage—they just can’t stay alive long enough to unleash their full damage potential before going down.

   VI. Evil Moon 13 Archer & Ranged Build Guide

   A. Archer Build: Mapping Efficiency and Skill Ceiling

   The biggest draw of archer builds is: insanely fast mapping clear speed.
   Archer projectiles are naturally great for clearing mobs, especially once you add mechanics like spread, pierce, bounce, and multi-shot into your gear and skills. The clear speed here is addictive.

   But here’s the catch with archer builds: if your skill links and gear stats don’t align, the play experience will be terrible.
   For example, if you want a fast multi-shot playstyle but your gear lacks attack speed and you haven’t linked projectile boosts, you’ll feel like you’re shooting slow and dealing no damage—your entire play experience will fall apart.

   B. Playstyle Differences: Spread Shot, Rapid Fire, and Projectile Builds

   • Spread Shot Type: The go-to mapping build, with extremely high mob clear efficiency—perfect for running around farming resources.

   • Rapid Fire Type: Focuses on consistent sustained damage, great for single targets and small groups of mobs, solid bossing efficiency, moderate gear requirements, ideal for players who like playing it safe.

   • Projectile Builds: Specializes in unique projectile effects like bounce and multi-projectiles, great for clearing mobs in complex terrain, has high attack flexibility, lots of room to customize gear, perfect for players who love varied playstyles.

   That wraps up the core gameplay, point allocation, and survival tips for the three main builds in Undecember: Melee, Mage, and Archer. We hope this helps new players get up to speed quickly and avoid common pitfalls!

   • Machine Gun-like DPS: Rely on attack speed and damage over time (DoT) to sustain your damage. It also performs pretty well against bosses.

   • Projectile Enhancement Route: Includes effects like penetration, bouncing, and multi-projectiles. This is the most varied playstyle for Archer builds, but it relies more on having good gear and a solid rune pool.

   If you're new to Archer builds, we recommend starting with a "stable map-clearing" route. This phase lets you farm resources quickly; once your gear's affixes start to take shape later on, you can switch to a projectile-specialized playstyle, which has a clearer upper limit and feels more smooth to play.

   C. Archer Build: Gear Affix, Attack Speed, and Critical Hit Synergy Tips

   Common core playstyle directions for Archer builds include:

   • Attack Speed Bonus

   • Critical Hit and Critical Damage Boost

   • Projectile-related Effects

   • Survivability Enhancements

   What's the most common pitfall Archer players stumble into?
   Trying to stack attack speed, critical hits, and projectile effects all at once while completely ignoring defense, ending up in a situation where "map clearing is fast, but you instantly die if you make one small mistake."
   To play smoothly, you need to accept one thing first: You must have a basic baseline of survivability. Otherwise, every death will eat up most of your map-clearing efficiency, which is not worth the loss.

   VII. Summoner Build Recommendations for Undecember

   A. Is the Summoner Build Suitable for New Players and F2P Users?

   The Summoner build is super newbie-friendly, and the reason is straightforward:
   Your summons take damage for you, so your death rate is low; low death rate means resource accumulation speeds up naturally.

   F2P players are also very suitable for Summoner builds. Most Summoner builds don't require you to max out your weapon's critical hit to deal damage—your summons can make up for damage or crowd control, so the early game pressure is much smaller.

   Of course, Summoner builds have downsides too: Some people feel like "it's not as satisfying as attacking yourself," or like watching your summons perform. It depends on whether you can accept this "steady and cautious" playstyle.

   B. The Difference Between Minion Summons and Bolt Summons

   Actually, we can distinguish these two Summoner builds by "who is the core combat power":

   • Minion Summons: You are like a commander, mainly responsible for buffing, assisting damage, and dodging. The summoned minions are your main source of damage.

   • Bolt/Mechanism Summons: More like setting traps, relying on summons or mechanisms to deal sustained damage. Map clearing feels smooth, but it requires more attention to positioning and rhythm.

   New players usually find Minion Summons or Semi-Summoner easier to get started with, because this playstyle is more intuitive and doesn't require very complex operations.

   C. Summoner Build Performance: Map Clearing, Boss Fights, and Stress Resistance

   The general feel of playing a Summoner build is:

   • Map Clearing Phase: High stability, low death rate, large room for error

   • Boss Fight Phase: As long as your summons can tank damage, you can keep dealing damage. The pressure is much smaller than playstyles that require close combat output.

   • Stress Resistance: Perfect for players who don't want to focus fully on operations every fight.

   The most common problem with Summoner builds is: If your summons are too fragile, or if you don't build a survivability and sustain chain, you will instantly lose your battle rhythm once your summons fall. So Summoner builds are not really "win while lying down" builds—they just shift the pressure from "you take damage directly" to "ensuring your summon system operates stably."

   VIII. Undecember Skill Rune and Link Rune Combination Guide

   A. How to Match Skill Runes to Your Build

   Before choosing skill runes, ask yourself one key question:
   Is the core goal of this build "prioritizing map clearing efficiency" or "focusing on stable boss fights"?

   • Map Clearing Focus: Prioritize runes that expand area, increase hit count, and improve mob clearing efficiency

   • Boss Fight Focus: Prioritize runes that boost single-target damage, sustained damage capability, and enhance your ability to stay standing.

   New players, don’t go for those flashy skills that need a ton of prerequisites to shine right off the bat. What you need most as a newbie is: core skills that are easy to build around, let you farm mobs consistently, and help you stock up resources.

   B. How Linked Runes Boost Damage, AoE, and Survivability

   Linked Runes can be roughly split into three main categories:

   1. Damage-Type: Includes damage boosts, crit bonuses, penetration effects, and extra perks for single-target or AoE targets

   2. AoE & Efficiency-Type: Includes effects like increasing skill range, adding more projectiles, penetration, bounce, and chain effects

   3. Survivability-Type: Includes effects like lifesteal, shields, damage reduction, health regen, and resistance-related effects

   The most reliable linking method for new players is:
   Make sure you have basic survivability first, then pile on damage.
   After all, if you die even once, your dungeon-clearing efficiency drops right away; lower efficiency means slower resource farming; slow resource gain makes your whole playthrough way more frustrating.

   C. New Players

   Rune Builds: The 3 Biggest Newbie Traps!

   Let’s call out three deadly mistakes new players almost always make with rune builds:

   1. The “All Damage, No Defense” Syndrome: Your damage numbers look insane, but you melt in one hit—you can’t survive dungeons or bosses, so your actual efficiency is the lowest of all

   2. Jumping Rune Sets Haphazardly: One day you want to play projectile builds, the next you’re obsessed with mages—you split your resources all over the place, end up with two half-baked builds, and get nowhere

   3. No Distinction Between Dungeon & Boss Builds: Use your dungeon-clearing runes on bosses, and your damage is as useless as tickling; use your boss runes for farming mobs, and you’ll clear enemies so slow you’ll fall asleep, completely mismatched to the scene

   Stop obsessing over the “always best” setup. The key is to prepare two different builds first:
   A rune combo suitable for dungeon clearing and a rune configuration suitable for boss fights. At the very least, you need to know how to switch between the two playstyles.

   IX. Full Guide to Zodiac & Attribute Point Allocation in Undecember

   A. How STR, DEX, INT Affect Different Builds

   Here’s the most straightforward explanation new players can grasp intuitively:

   • STR (Strength): Directly corresponds to melee builds, survivability, defense, and equipment or skills that require a Strength threshold to equip or activate

   • DEX (Dexterity): Corresponds to projectile damage, attack speed, hit chance, crit rate—all builds related to Dexterity rely on it

   • INT (Intelligence): Exclusive to mage builds, spell damage, elemental boosts, cast speed, and all needs related to energy (mana) values

   But always remember: More attribute points don’t make you stronger. They’re also the entry threshold for equipping gear and activating skills!
   Putting points on the wrong attribute not only reduces your damage, but also may cause you to be unable to equip specific equipment or make skills not perform at full potential, making your whole play experience really bad.

   B. How Zodiac Point Allocation Complements Weapons & Skills

   Zodiac point allocation is recommended to follow the principle of “grasp the core first, then fix the weaknesses”:

   1. First, max out the direction of your main damage source:

   2. Projectile builds → Prioritize projectile damage, attack speed, crit rate, and related bonus effects

   3. Mage builds → Prioritize elemental damage, spell bonuses, cast speed, or Damage Over Time (DOT) bonuses

   4. Melee builds → Prioritize melee damage, attack speed, and survivability attributes

   5. Summoner builds → Prioritize minion damage, minion survivability, or attributes that boost yourself

   6. Then, fix your weaknesses:

   7. Getting one-shot too often → Prioritize survivability

   8. Low boss-clearing efficiency → Prioritize single-target damage

2. If you're slow at farming, prioritize boosting area damage efficiency.

This way, your talent builds will feel intentional, not like a random hodgepodge—your damage and overall playstyle will feel much smoother.

C. Respec Timing & Key Avoidance Tips for Early/Mid-Game Builds

Respec is an extremely important adjustment tool for new players, but never use it as an excuse to spam points randomly.
Stick to these principles:

• Don't rush to respec early on—respecing before you've locked in your core skill will only mess up your build more.

• Only consider a respec when you actually need to switch playstyles, or when your current build clearly makes you unable to equip gear, get oneshot, or have a massive damage gap.

• The most important tip: Never try to run two completely different builds at the same time! Focus on getting one build to a point where you can farm consistently, take down bosses, and accumulate resources before touching a second build.

X. Undecember Early Game Builds & Progression Path

A. Standard Early-Game Leveling Strategy from Level 1 to Mid-Game

The core logic for early game is super simple: Clear acts, farm resources consistently, and stay alive.

Here's a progression guide for mid-game:

1. Pick one core skill as your main damage source.

2. Prioritize leveling and linking that core skill—this is the most noticeable improvement you can make early on.

3. For gear, just focus on whether it's usable and helps you survive—don't chase perfect, top-tier gear right away.

4. If you hit a wall, adjust links for survival or single-target damage—don't respec your entire build from scratch.

5. Once you're farming resources consistently each day, start working on improving damage efficiency and maximum potential.

The biggest mistake in early game resource allocation is "equal distribution"—you must prioritize specific things:

Main Weapon is Top Priority: Most of your damage comes from your main weapon—don't underestimate it.Survival Foundation: Pick at least one direction to boost your defenses: resistances, life, armor, or shields. You can't get oneshot every fight.

If you waste resources on random small things early on, you'll end up with a build that looks like it has everything, but nothing is strong enough—you'll get destroyed by slightly tougher enemies.

C. Which Playstyles Are Good for Fast Leveling & Consistent Act Clearing

If you want to level fast and clear every act reliably, these are the key playstyles to focus on:

Here's another super helpful tip for new players:
Safe-range mages, projectile builds, DOT builds, summoners, or semi-summoners
It's not that melee can't work, but melee requires much more "survival knowledge"—new players often get oneshot before they even learn the mechanics, making it way harder.

XI. Undecember Gear System & Endgame Gear Goals

A. How to Evaluate Weapons, Armor, and Attribute Requirements

When you get new gear, don't get excited just because it's high rarity—ignore the power score for a second, and focus on these three core things:

The most common new player mistake is picking up gear that looks awesome, only to find you don't have the attributes to equip it, or its affixes don't fit your build at all—wasting time on something that doesn't give you damage. This can make the game feel unfun really fast, so you need to learn to "pick gear based on your build" instead of "pick gear based on rarity".

B. Priority Order for Enchanting, Gear Quality, Affixes, and Upgrades

If you don't know where to start, here's a player-tested priority order that works every time:

Many new players get this backwards: they chase perfect affix gear right away, then can't kill enemies, die constantly, and never even get a chance to farm materials—let alone get "endgame gear".

C. Key Affixes to Chase for Different Playstyles

I'll explain this simply so you can apply it directly to your build:

XII. Undecember Endgame Content: Chaos Dungeons, Raids, and High-Level Content

A. How Endgame Builds Differ from Early/Mid-Game Builds

The requirements for early/mid-game builds are simple: clear acts, farm materials, and don't die too much to be considered good.
But in the endgame, you'll start chasing higher goals:

You'll notice some builds that worked well early on can still work in the endgame, but you need to "specialize" them and perfect every detail—otherwise, you won't even get access to high-level content, you'll just be stuck outside.

B. Chaos Dungeons

Raids Bosses: Requirements for Build Styles

High-end content like Chaos Dungeons and raids actually boils down to three core skills to master:

When you get to this point, you’ll realize one thing: Staying alive is way more important than flashy damage numbers. So many late-game players get fed up not because their damage is low, but because they get one-shot the second they step into a dungeon—never even getting a chance to actually play their build.

And dying? It kills your ongoing damage output completely—total waste!

C. How to Transition from Starter Build to Endgame Build

The smoothest transition method is: Don’t toss your current setup entirely—gradually swap out just the core parts.

Here’s how to do it:

This way, you’ll never get stuck in that brutal cycle:
“Want to switch builds but can’t clear maps; can’t clear maps so no resources; no resources so can’t switch builds”
New players hate being trapped in this mess late-game.

XIII. Undecember Frequently Asked Questions (FAQ)

A. Which Class is Strongest in Undecember?

The general consensus among players is: There’s no absolute strongest class—only the build that fits exactly what you want to do right now.
If you want super fast map clears, projectile or AoE damage builds work great.
If you want stable boss fights, focus on single-target damage and sustain instead.
If you’re a free-to-play player trying to save resources, DOT or summon builds are usually way easier to handle.
So before asking “which is strongest”, tell people what content you’re playing—then you’ll get the right answer.

B. What’s the First Class New Players Should Pick?

If you’re totally new and don’t want to mess up early: Safe playstyles like ranged magic, projectile builds, DOT, summon, or semi-summon builds are all highly recommended.
Get used to the game’s story chapters and resource paths first—you can switch to melee, crit builds, or high-potential builds later without any issues.

C. Which Class (Mage, Warrior, Archer, Summoner) Is Least Resource-Heavy?

Generally speaking:

So the real key to saving resources isn’t the build name—it’s: you die less, clear maps faster, and focus your resources on the important parts—that’s how you actually save.

D. How to Fix a Mistake in My Early Build?

Here’s a super practical fix order for you:

Lots of people think they picked the wrong class, but most of the time it’s just that they used resources on the wrong things—making the game way harder than it needs to be.

The keyword “Undecember Classes” might seem like you’re searching for the “strongest class”, but once you play the game, you’ll get it:
The strongest thing in this game isn’t the class—it’s building a setup that’s “fully figured out”, “complete”, and fits exactly the content you want to play.

• Skill Levels and Gem Links: The most obvious way to boost damage early game—focus on these first.

• Main Weapon Priority

  • Fast map clear speed

  • Hard to get killed

  • Low barrier to get the build working

  1. Can you meet the stat requirements?

  2. Are the modifiers (affixes) on this weapon a perfect match for your build?

  3. Does this item fix your build’s current weaknesses?

  1. Core modifiers on the main weapon

  2. Resistances and base survival stats

  3. Stats tied to map clear efficiency

  4. Only at the end: Perfect modifiers and high-quality gear

  • Melee Builds: Prioritize leech/health restore, armor/damage reduction, resistances, life—then finally damage and attack speed.

  • Magic Builds: Prioritize element/magic damage, cast speed, crit chance/crit damage, resistances, and survival abilities.

  • Bow/Projectile Builds: Prioritize attack speed, crit chance/crit damage

Summoner Builds: Prioritize minion damage and survivability, your own defensive skills, and support abilities – your personal damage stats come last.

• Faster map clearing and dungeon run efficiency

• Better reliability – no one wants to wipe constantly in dungeons

• Clearer role definition (whether solo or in a party)

• Need precise, well-tuned stats

1. Survivability: Resistances, damage reduction, and sustain are absolutely critical. If you don’t have enough, the boss will take you down in just a few hits.

2. Single-target damage: After all, you can’t drag out boss fights forever – speed is the key here.

3. Mechanic Handling: Can you deal damage while dodging skills? Can you keep up sustain during chaotic battles?

1. Keep the core skills that work smoothly for you.

2. Next, swap your link runes from the “more stable, beginner-friendly” set to ones that boost “end-game efficiency” or “single-target damage.”

3. Tweak your Zodiac configuration to fix your character’s weaknesses.

4. Swap out gear one piece at a time, prioritizing your main weapon and survivability-focused items.

5. Wait until your end-game stats and rune pool are mostly set, then think about a full BD (Build) overhaul.

• Summoner/DOT-type builds are usually more resource-efficient – you don’t need to rely on max crit chance or perfect stats to deal consistent damage.

• Projectile bow builds have great clearing speed, but they’re more sensitive to attack speed and stat consistency to keep smooth playfeel and damage output.

• Melee builds aren’t actually super resource-heavy if you build up survivability first – but new players often think they are because they die a lot, pay high repair costs, and have slow clear speeds.

1. Don’t rush to reroll your character.

2. Check if you’re spreading your resources too thin: are you leveling too many skills? Swapping link runes randomly? Pointing Zodiac nodes without a plan?

3. First, salvage the build that can at least clear maps: use link runes focused on survivability and stability, prioritize resistance gear, and optimize/upgrade your main weapon.

4. Once your map clearing speed is back, you can start transitioning slowly.
