Cheese Trap: Max Rewards
The alliance rat-boss rally: personal five-phase rewards, the shared alliance HP pool, why join order means nothing, and the level-scaling math that decides which rat to fight.

🗓 Updated: 2026-09-03
Cheese Trap is an alliance PvE rally event against a giant rat. Your personal damage earns personal rewards across five phases, and the alliance’s total damage earns separate alliance rewards. It looks like a pure power event — it is actually a planning event, and the difference is worth several reward tiers.
This guide covers the two reward tracks, the stop-point rule, level scaling, and how to read the rankings before your alliance commits to a rat.
How It Works
- An R4 or R5 sets the start via the unified Event Schedule. From that click the alliance has about 1.5 hours to attack.
- Cursed Land Placement Forbidden: Since the July 2, 2026 update, placing new Cheese Traps in the Cursed Land is no longer permitted.
- Cheese Trap I and II differ only in time — same rat, same rules, different window. Pick whichever fits your schedule.
- You can only fight ONE of the two rats. There is no splitting your troops across both.
- Offline participation works — join the rally ahead of time and your squads fight even if you log off. Set your march before the window opens, then live your life.
The Two Reward Tracks
| Track | Based on | Rewards |
|---|---|---|
| Personal | Your own damage | 5 phases of escalating rewards |
| Alliance | Alliance total damage | Alliance-wide reward tiers |
The interaction between the tracks is the important part:
- STOP after personal Phase 5. Damage past that point is pure troop loss — zero extra personal rewards for the troops you burn.
- Both rats share one HP pool for alliance rewards. If one player reaches Phase 5 on one rat and another stops at Phase 3 on the other, the alliance total counts as if everyone hit Phase 5. The pool — not the phase — is what matters.
Rally Mechanics: What Actually Matters
- Joining an R4/R5 rally grants +2.5% attack. Join the rally instead of solo-marching. Every time.
- Rally initiator strength and join order have ZERO effect on your damage. Joining first does not hit harder; joining last does not leech. Stop jockeying for position — it changes nothing.
- Every troop deals damage. The rat’s HP pool is enormous, and no single heavy hitter can “use it up” — a full march of cheap troops out-damages a half march of expensive ones. Bring bodies, not just elites.
Level Scaling: Which Rat to Fight
The level decision has a clean rule:
Phase 4 of the next-level rat is marginally better than Phase 5 of the previous level — and pays better total rewards.
In practice:
- Established alliances run level 7 or 8.
- Near a KvK day, pick level 7 — you want troops alive for the war, and the marginal reward of level 8 is not worth the extra losses.
Before committing, check the rankings: count the players hitting Phase 5 on the level 6 rat versus the players reaching Phase 4+ on level 7. If more of your roster clears P4 on 7 than P5 on 6, the higher rat is the better call.
Reading the In-Game Rewards Table
The full rewards table is in the game: Special event > Cheese Trap tab > Gift button > Rewards. Read it before the rat opens — the phase-by-phase comparison tells you exactly where your roster’s stopping point lands.
Team Setup
Squad priorities for a long boss fight:
- Survivability + sustained DPS + synergy. The rat is a marathon, not a burst check.
- Tanky frontline — heroes that stand for the full fight.
- Strong backline — the damage engine behind the frontline.
- Support-healer — keeps the frontline alive, which keeps the backline safe, which keeps damage flowing.
Specific hero picks and faction synergies are in the Heroes guide.
The Whale-Carry Option
If your alliance has one heavy hitter, there is an efficient endgame pattern: 2-3 rallies are enough to max alliance rewards when the whale carries the damage. Everyone else joins the rally for the +2.5%, drops their troops in, and stops at their personal Phase 5. The whale’s damage fills the shared pool; the alliance tier fills; nobody burns troops past their own stop point.

❓ FAQ — Frequently Asked Questions
What is the best F2P team in Last Asylum: Plague?
The canonical F2P squad is Arthur, Daskal, Marlena, Harper, Claire (all Warriors — mono-faction gives +20% HP/ATK/DEF). Arthur is free from day 1; the $1 Marlena top-up is considered the best value in the game. Daskal arrives in the first Era of Revival season (day 120+).
What should I upgrade first?
Sanctuary first, always — it gates every other building and your hero level cap. Then Training Grounds, Barracks, Research Lab, Infirmary, Wall. Keep the Builder’s Hut at Sanctuary level until Sanctuary 15 for free construction speedups.
When does Marlena unlock?
Day 66 for free — or immediately via the $1 starter top-up. Save UR shards so she lands at 8★ right away, then push 10★.
How do I get Cynthia as F2P?
Cynthia arrives via the Wishing Wheel on day 8. Save diamonds from day 1 (skip everything else) — ~11,500 diamonds total, and always spin ×10 (single spins waste tokens).
How do I get antitoxin?
Antitoxin Workshop + Stable production, every building upgrade completion, Falcon Quests (nearly all of them), Covert Ops and Caravan Trade (including plundering others’ ops — up to 5/day), and Blight/Elite Blight hunts (10/20 stamina). Events pay large amounts.
Why did my plunder income drop to almost nothing?
You hit the daily plunder limit: below the limit 100%, from 1× the limit you keep only 15%, from 1.3× only 5%. It resets at 02:00 UTC. The limit scales with Sanctuary level (2.5M at Lv.10–12 up to 30M at Lv.30) and rises immediately when you upgrade Sanctuary. A yellow triangle under your Might shows the status.
What should I buy in the shops?
Sanctuary/Expedition/Alliance shops: Crow Essence and UR Hero Omnifragments first. Honor shop is for gear blueprints only (never epigraph chests there). All shops restock Monday.
Are diamonds worth spending on speedups?
Only the VIP-shop 8h speedups are considered acceptable purchases — and only after hero resources. Community rule: never dump diamonds into speedups over hero wheel events (Cynthia day 8, Joker after day 15).
What faction should I build?
Warriors are the best early game (free Arthur/Harper shards, $1 Marlena). Rangers peak mid game (counter Warriors). Warlocks are the best late game but need heavy long-term investment. Mono-faction (5 heroes of one type) is the current meta because UR epigraphs buff a single faction.
How does Claire SSR→UR conversion work?
Opens on Era Day 8. She lands at 6★ and the run to 10★ costs 1,600 SSR shards (each substage costs 2× the SSR price). There’s a team-buff dip between 6★–9★ — skip it by banking Hall of Honor levels before converting (Lv.60→8★, Lv.100→9★, Lv.160→instant 10★).
How do I redeem gift codes?
In-game: Avatar (top-left) → Settings → Gift Code. iOS or web: log in at the official redemption page with your linked Facebook/Google account, pick server and character, enter the code.
What are the biggest beginner mistakes?
Upgrading everything equally instead of one main squad; judging heroes before high stars (Marlena is the classic late bloomer); splitting Awakening materials across heroes; wasting gems on VIP levels over hero wheels; skipping daily plunder (~27M resources/day); letting stamina cap.
