Assault Lily Complete Beginner's Guide: Everything You Need to Know About Starter Gacha Pulls &

If you clicked this guide because you're all about Assault Lily – I totally get what's on your mind:
"Isn't this the series where girls use super cool CHARM weapons to fight Huge monsters? How do I play this so I don't get hooked for the first few days, only to hit a wall and get annoyed two weeks later?"

Let's be real: Assault Lily Last Bullet might look like a gacha RPG at first glance, but it's actually more of a team-building and memory card-focused training RPG! You can totally chill and just play for pulling your favorite characters, but if you want to play smoothly, earn more event rewards, and not get crushed in PvP ranks, you need to nail these three key points:

1. How to do a fast and efficient starter roll

2. Character strength depends on role synergy, not just rarity

3. CHARMs, memory cards, and team composition are everywhere – you need a priority list for who to level and what to upgrade first

1. Introduction & Basic Game Overview

Core Overview

I'll make this guide a "check while you play" practical resource:

• When you're new and lost: Head to Chapter 2 for starter roll tips and Chapter 3 for character system breakdowns

• When you hit a hard wall: Check Chapter 4 for CHARM/memory card upgrades and Chapter 6 for training order advice

• When you want to grind PvP ranks: Study Chapter 5 for mode rules and Chapter 11 for advanced PvP tips

• When you want to avoid mistakes: Chapter 9's FAQ has all the common player mistakes I've compiled

In short: You don't need to memorize the whole guide – just remember which section to check when to save time.

Game Background & Core Lore

Assault Lily is a multi-media franchise spanning stage plays, anime, merch, and now the mobile game Last Bullet. The core lore is super straightforward:

• Humans fight against mysterious alien threats called Huge

• The Lillies' battle weapons are special equipment called CHARM

• Everything you do in the game boils down to building and leveling up your Lily team to be stronger and more complete

What makes Last Bullet special is that it's not just a hack-and-slash action game – it focuses heavily on team composition. Your team and character builds usually involve elements like Lilies, memory cards, CHARMs, Orders, and sub-slots, so it's a heaven for players who love training systems, but might feel overwhelming for casual players.

2. Starter Roll Guide & Early Game Prep

Let's answer the most practical question on everyone's mind: Should you do a starter roll?
If you're planning to play for free or spend a little and stick around, I'd say: It's worth doing, but don't overdo it and waste too much time.
After all, real character strength in this game comes from combining memory cards with CHARMs and team synergy later on – not just the first few cards you pull at the start.

Starter Roll Process & Mechanics Breakdown

The common fast reroll process is roughly like this:

1. Install the game → Complete the tutorial → Finish downloading in-game resources → Choose your Legion → Pick your starting character → Pull from the tutorial-exclusive gacha pool

2. Claim all available rewards → Pull from every gacha pool you can access → If you're unhappy with the results, reroll

 

Here are some essential tips that every player needs to know, converted into practical advice you can easily understand:

• Rerolling takes roughly 10 to 15 minutes

• The drop rate for the highest rarity cards is 3%

• Some tutorial gacha pulls come with fixed pity systems or guaranteed acquisition mechanics

• Android players can usually reroll by clearing the game's data, which is way faster than repeatedly uninstalling and reinstalling

• If you've linked accounts to the PC version, rerolling can become a hassle or even impossible, so it's best to do rerolls on mobile first

Here's my personal advice for new players:
Stop rerolling once you get a "comfortable enough" starting team—don't chase perfection, because losing even one day of event and material progress will cost you far more resources than getting that one perfect card would.

B. Early Roll Character Recommendations & Rankings

Many new players fall into this trap in this game:
"I pulled a popular character, but now I can't progress through the main story at all"
It's not that the character is weak— it's that your team is missing key functionalities.

That's why I've split my early roll recommendations into three types that'll make your game flow way smoother once you pull them:

1) The Most Reliable Starter: Buff/Support Core That Powers Up the Entire Team

Look for these types of cards:

• Those that boost the entire team's attack, critical hit chance, and action speed

• Or ones that help with energy regeneration, speed boosts, and make your damage dealer's rotation smoother
  These cards will stay useful in your team no matter who your main damage dealer is later on.

2) Story Progression Lifesaver: Consistent Survival Core (Healing/Shielding/Damage Reduction)

90% of the time new players get stuck is because they can't survive, not because their damage is too low.
If you have a solid healer or shield card, the main story will feel twice as easy to progress through.

3) Most Fun to Play: Burst Damage Dealer

Burst damage is really fun, but here's the catch:
If you only have burst damage dealers, no supports, and no survival, you'll end up dealing massive damage but dying first.
That's why I rank burst damage as third priority— great to have, but don't stress if you don't get one right away.

If you really want a "checklist" goal:
You can check out the community's tier lists for the strongest characters as a reference, but I still recommend using the three functionalities above to judge, since tier lists change with updates.

C. Starting Team Composition

The starting team skeleton I highly recommend for new players is 1 Main Damage Dealer + 1 Sub-Damage Dealer/Armor Breaker + 1 Buff Support + 1 Survival Unit + 1 Flex/Mobility Slot.

• What's the Flex/Mobility Slot?
  You can put in crowd control, a second support, or a function-specific card for certain stages.
  This slot is key for solving and clearing stages later on.

Once you build this skeleton, you should be able to clear the main story, material dungeons, and event beginner stages without much trouble.

III. Character System & Strength Evaluation

A. Character Classification & Role Definitions

In "Last Bullet", you need to get used to one thing:
"A character's strength often varies a lot based on their outfit/memory cards"
That means even the same character can have wildly different playstyles when wearing different outfits and using different skill sets.

I'll categorize them using 5 roles that are most intuitive for players:

1. Main Damage Dealer: Responsible for breaking through enemy health bars

2. Armor Breaker/Resistance Down: Responsible for making enemies more vulnerable, so the main damage dealer can deal massive damage

3. Buff Support: Responsible for making the entire team's rotation smoother and damage more consistent

4. Survival Unit: Responsible for keeping the team from getting wiped

5. Crowd Control/Disruptor: Responsible for limiting the enemy's actions— super crucial especially in PVP

To judge if a character is strong later on, just ask one question:
"Can they provide an irreplaceable function to the team?"

If it works out, it’s a solid investment that won’t leave you disappointed. If not, it’s probably just a fun temporary card that won’t stay relevant long.

B. Character Tier Ranking & Analysis

I’m not gonna dump a random "T0 today, T2 tomorrow" tier list here—those lists get outdated fast anyway. Instead, I’ll use a more sustainable system: split strengths into four categories: "General Use T0 / Situation-Specific T0 / Resource-Friendly / Late-Game Investment".

General Use T0: Works in both PvE and PvP, and fits into almost any team comp

Usually, the top picks here fall into three categories:

• Super-buff supports that give your entire team huge boosts

• Reliable healers or shields that keep your team alive consistently

• Strong utility cards that can break defenses or lower enemy resistances

These three types should be the core building blocks of your account.

Situation-Specific T0: Shines in certain game modes

• Cards that excel at initiating control in PvP

• Perfect counter picks for specific stages/dungeons

• Puzzle-solving cards for high-difficulty event stages

The thing about these cards? You can still clear content without them, but getting them makes clearing way less stressful and way easier.

Full Marks for Resource-Friendliness: Makes the biggest difference for new players or F2P (Free-to-Play) users

That doesn’t mean these are the strongest cards out there—they just give you way more value for the resources you put in:

• Don’t need high limit breaks to be useful

• Shine once you get their skills to a decent level, no extra grind required

• Perfect as your go-to utility cards for the early to mid-game

Late-Game Focus: High ceiling, but requires long-term planning

These cards are usually either high burst damage dealers or advanced control units. You need to invest heavily into them to unlock their full potential—otherwise, their early-game strength won’t even match the resource-friendly cards we talked about earlier.

If you really want to check community-made lists like the "Strongest Lily Rankings", players do update those regularly. But I still recommend: Start by checking the cards you’ve pulled against the categories we just talked about—that way, you won’t feel lost as you play.

C. Character Countering & Team Synergy

Ever had this happen? You’re around the same power level as the enemy, but can’t beat them—then swap in a couple utility cards, and suddenly you breeze through? That’s team synergy at work.

I’ve broken down the most common team synergy issues into three big categories:

1. Only has damage, no defense break or buffs → You deal almost zero damage, it feels like scratching a wall

2. Only has damage, no survival tools → You get wiped before you can finish the stage

3. Lots of control effects, but no finishing damage → You finally lock down the enemy, but can’t kill them—then they wake up and counter you

So when building your team, here’s the most practical checklist to run through:

• Does my team have skills that break defenses or lower enemy resistances?

• Do I have support characters that give buffs to make my team’s battle cycles smoother?

• Do I have healers or shield characters to keep my team alive?

• Does my team rely on "burst and kill quickly" or "steady chip damage to win"?

IV. CHARM Equipment & Strengthening System

Let me cut to the chase here: Lots of players get a good first pull card, but then their power gets stuck—all because they messed up how they level CHARMs and Memory Cards.

A. Deep Dive into CHARM Equipment System

CHARMs aren’t just fancy decorations—they’re key parts of your team’s damage, survival, and battle mechanics. Plus, when building teams, CHARMs work together with Memory Cards, Orders, and other elements.

You can start judging a CHARM’s strength the easiest way possible:

• Stat boosts it gives

• How it affects the battle rhythm

• It

 

B. Memory Card Enhancement Mechanism – The Real Core of Character Growth

Lots of guides make memory cards sound super complicated, but new players only need to nail two key points to get started:

1. First, level up the memory cards linked to your main DPS characters to their max level

2. Then, boost support memory cards that give your team buffs or survival bonuses until they’re strong enough to consistently clear daily content

Memory card enhancement has its own dedicated progression system, and it’s one of the most common go-to ways players grow their characters every day.

C. Enhancement Priority Guide

I’ve got a solid, reliable enhancement order that almost never leads to regret—just follow this:

1. Lock in your 5 core main team characters first

2. Prioritize leveling up the core memory cards for your main DPS character

3. Next, enhance support memory cards that deal defense-breaking or provide useful buffs

4. Finally, wrap up the enhancement of survival-focused memory cards

5. As for CHARM upgrades? Only do them when you hit a stage wall—don’t burn all your growth materials on them early on

Player Pro Tip:
If your resources are limited, always remember this rule:
It’s way better to build one solid team than half-ass three teams at the same time

V. Core Game Modes & Dungeon System

A. Main Story Dungeon Key Points

Many new players think the main story is just for unlocking features, but it’s actually the foundation for all your future progress—here’s what it really does:

• Unlocks daily material-specific dungeons you need to farm regularly

• Opens up more party slots and character progression systems

• Builds a steady resource stream so you’ll never run out of materials for later growth

My advice for new players: Focus on pushing the main story for your first week. Once you truly hit a wall and can’t progress anymore, then go back to planning your growth resources. Don’t get hooked on gear farming or events early on and stall your main story—missing that early game momentum is a huge mistake.

B. Limited-Time Events & Special Dungeons

The various event dungeons the game releases have awesome rewards, and you can grab these main things:

• All kinds of materials needed for character enhancement

• Rare resources for the event-exclusive exchange shop

• Sometimes, there are insanely good limited-time exclusive items

My core strategy for event dungeons:
First, get to a difficulty you can consistently farm easily, then go challenge higher stages later
After all, reliable farming means steady daily gains. Pushing for a high difficulty you can’t clear consistently is just a waste of stamina and time—totally not worth it.

C. PVP Competition & Ranking System

The key factors that win or lose PVP in this game boil down to three things:

• Party turn order (first attack priority)

• Effective use of crowd control skills

• High burst damage to finish off opponents
  If you’re getting crushed in PVP all the time, it’s probably not that your characters are too weak—it’s that your team is missing one of these core mechanics: “turn priority, crowd control, or survival tools”

VI. Character Progression & Game Progress Planning

A. Character Level & Upgrading Rules

You actually get a fair amount of in-game resources every day, but the most common mistake new players make is:
Spreading resources evenly across all characters
The result? No character is strong enough, and you can’t clear any stages at all.

My suggestion for you:

• First, focus on max leveling up your main party members first

• Put other characters on hold for now—just use them as bench players for later

B. Character Development Priority Order

1. Main DPS Character

 

1. Buff/Defense-Break Support Characters

2. Team Survival Characters

3. Crowd Control Characters

C. Resource Management & Daily Resource Farming

I recommend structuring your daily game routine like this:
Finish all fixed daily dungeon runs first each day.
Next, head to event-exclusive dungeons to farm event-specific exchange resources.
If you hit a wall later, go back to upgrading your team. This plan will keep your account growth super consistent—no random spikes or drops in power.

VII. Gacha Mechanics & Spending Guide

A. How the Gacha System Works

When pulling gacha, new players get tripped up by two things all the time:

1. Chasing the strongest character on the current banner

2. Caving to the urge to get limited-time characters

But always remember:
This game’s power comes from your full team and system synergy—not a single character card.

Also, the official stated rate for 5-star characters is around 3%—if you try to pull every limited or top-tier character per banner, your wallet won’t hold up.

B. First Purchase Bundle & Spending Advice

I won’t tell you to buy random bundles—instead, I’ll teach you how to spot which ones are worth it:

• Does it boost your daily game loop efficiency?

• Does it fill a core gap in your team?

• Does it offer long-term, consistent returns?

Bundles that check all three boxes almost never disappoint. On the flip side, those "looks like a ton of stuff but it’s just random junk" bundles—you’ll likely buy them and never use anything inside.

C. F2P & Different Spend Tiers Guide

• F2P Players: Just grab all event resources and focus on leveling your main team—you’ll play totally smoothly.

• Light Spenders: Pick up efficiency-focused bundles; it’ll make your experience way nicer than F2P.

• Whales (Big Spenders): Even though you can go for full character collections, you still need to nail down team composition and upgrade order first—otherwise, you’ll waste a ton of money.

A common early-game hassle for players in Last Bullet is buying a bunch of "luxury storage" bundles they’ll never actually use.

VIII. Coupon Codes & Redemption System

This chapter is super important because Last Bullet has two redemption codes that are easy to mix up:

• Redemption Keywords (Japanese: プレゼントキーワード)

• Serial Codes (Japanese: シリアルコード)

A. Redeeming Coupon Keywords

Official streams or events often share "Redemption Keywords"—players just need to enter them in the correct in-game input spot to claim rewards. Lots of game fan sites compile all the latest keywords and their matching prizes, plus clearly note "must enter via the specified in-game announcement form" to make checking easy for players.

B. Claiming Serial Codes – iOS Players, Pay Attention

Here’s a huge pitfall to avoid:
iOS versions can’t usually input serial codes directly, due to platform restrictions. If you use an iOS device, the most common fix is linking your mobile game account to the PC version, then entering the serial code on PC to claim your reward. Serial codes are generally used for these things:

• Pre-order bonuses for physical products/BDs

• Rewards included with event tickets

• Official merch giveaways

The devs will always announce in advance that the serial code’s corresponding bonus will be sent to your in-game gift box after entering it into the correct game version.

Redeem.

IX. Newbie FAQs & Solutions

A. Reroll Related Questions

Q1: Do I have to reroll until I get the strongest T0 character?
A: Nope. Just get two of the three core types: Buffer, Survivor, or Breaker, and you’ll already have a super smooth start. Sure, nailing that "perfect trio" feels great, but every day you delay starting events means losing out on actual resources and rewards—don’t overstress about rerolling too much.

Q2: What’s a reasonable time to spend rerolling?
A: Set a time limit for yourself—like one night or stop once you hit your goal. Each reroll takes 10-15 minutes, so it’s easy to get carried away and waste unnecessary game time.

B. Character & Team Questions

Q3: I have a ton of DPS characters but still can’t kill enemies—what’s wrong?
A: Chances are you’re missing two core things: Breaker effects or Buffs. DPS alone struggles to break enemy defenses or boost damage, but when you pair Breakers and Buffs, your damage will suddenly look way better.

Q4: My characters keep dying—how do I fix this?
A: Quickly add Survivor-type characters, then check if you’re spreading your growth resources evenly, which leaves every character too weak to survive hits.

C. Progression & Growth Questions

Q5: Should I level up CHARMs or Memory Cards first?
A: In most cases, optimizing your main character’s Memory Card levels and key abilities will feel more impactful, since Memory Cards are a big source of power. CHARMs are crucial for closing gaps when you hit a wall, so you can focus on them later.

D. Technical & Download Issues

Q6: Where do I enter the redemption code?
A: Usually there’s a "Redemption Code" option in the game’s top-right menu. Note that iOS can’t enter codes directly—you’ll need to link your account via the PC version to do it.

X. Version Updates & Meta Analysis

Update Date: January 16, 2026

A. New Version Features

First, a super easy-to-miss detail: *Last Bullet* has not only the original Japanese version, but also overseas/Traditional Chinese versions, and their service status has changed before. So before you follow this guide, double-check which version you’re playing to avoid mismatched info and mistakes!

B. Current Meta

This type of gacha RPG’s meta usually shifts between three states:

1. Burst Meta: Teams that go first and wipe enemies fast are super strong

2. Durability Meta: Shield and Healer characters dominate, and wearing enemies down is more reliable

3. Control Meta: Controlling the enemy almost guarantees a win, so immunity and dispel skills are way more valuable

You don’t need to memorize every meta shift—just observe: What kind of teams always crush you in the Arena?

• If you get wiped first: You need more Survivors, fast teams, or burst defense measures

• If you get worn down: You need more Breakers or sustained DPS

• If you get CC’d nonstop: You need more CC immunity, dispel skills, or resistance

C. Future Growth Predictions

I highly recommend prioritizing three types of characters that will never go out of meta:

1. Buffer supports that boost the whole team’s power

2. Survivor units with reliable survival skills

3. Breaker function characters that lower enemy defense/resistance

XI. Advanced Gameplay & Pro Tips

A. Advanced PVP Arena

Want to play competitive PVP? It’s not about "do you have that rare card?"—it’s about these key details:

 

My in-game tip:
Focus on beating opponents with the same Combat Power (CP) first. Don’t go after the very top players on the ranked ladder right away—they usually have a big advantage from resource grinding, and forcing it will just burn you out.

B. Guide to Challenging Dungeons

Most of the time, getting stuck in a dungeon isn’t about not having enough CP—it’s about using the wrong approach and forcing your way through.

C. Resource Optimization & Management

Pro players’ secret is simple:
Complete high-reward content daily, invest all resources into your main team, and buy everything you can from the event shop.
Stick to these three things, and your growth curve will be smooth and fast.

XII. Official Info & Community Interaction

A. Official Channels & Announcements
This game often releases rewards and update info through these channels:

B. Community Interaction & Tips
I recommend doing two things:

《Assault Lily Last Bullet》is really fun, but not in that "click-and-get-instant-gratification" type. Once you set up your team’s core structure, figure out the training order, and level up your CHARMs and Memory Cards, you’ll enter a comfortable rhythm—you’ll push through stages smoothly, handle events steadily, and even perform consistently in PVP.

Finally, I’ve condensed the most important core points into a version you can pin in your notes:

If you want more precise help: Send me your current main Memory Cards and the dungeon you’re stuck on, and I can make you a custom "7-Day Starter Training Plan + All-Purpose Team Build + PVP Backup Slots" list. Follow this plan, and you’ll get off to a steady, fast start.

• Turn order management

• CC skill chain combo

• Phase management for the final blow stage

• Survival tactics

  1. First, fill in your team’s function gaps: prioritize picking up survival, defense-penetration, or support roles depending on what you’re missing.

  2. Adjust your mobile character lineup: bring control, dispel, or counter cards based on the dungeon’s needs.

  3. Finally, handle the training details: don’t neglect Memory Card levels, CHARM upgrades, and skill rotations.

  • Official announcements

  • Keywords from live broadcasts

  • Serial codes that come with items/events
    You don’t need to follow all of them, but at least stay on top of one official channel to not miss any rewards.

  1. Join an active legion (レギオン, the in-game term)

  2. When you get stuck, ask the right questions: Are you missing damage? Survival? Or understanding of the dungeon mechanics? Asking correctly can save you a week of trial and error.

  • Don’t stress too much over your starter roll—stop once you get a card with useful functions, no need to obsess over rarity.

  • Focus on team function first, not just rarity.

  • Concentrate training on one team: Prioritize Main Carry → Support/Break Defense → Survival → Control.

  • Differentiate between gift codes and serial codes: Keywords vs シリアルコード; iOS serial codes sometimes need PC-linked redemption.

  • When stuck, adjust team synergy first before upgrading—don’t force your way through.
