Cheese Trap is an alliance boss event in Last Asylum: Plague, activated by R4 or R5. Good preparation, short marches, and coordinated rallies help your alliance deal more damage and earn better rewards.
Before anything else: empty your hospital
Bring your hospital count down to zero before the trap drops. Troops that overflow the hospital during this event are permanently lost. Make this your first preparation step.
Set the event and assign your players
- Have 20 alliance members ready. The trap requires 20 alliance members.
- R4/R5 must choose a difficulty and start time. Complete this before 22:00 server time on the final day of the event, or the trap expires unused.
- Choose Trap I or Trap II for each player. Players cannot participate in both. Send lower-power members to Trap I and reserve your strongest accounts for Trap II.
Prepare before kickoff
Donate only until the damage bonus is capped
Preparation donations increase your damage bonus up to its cap. Further donations still earn contribution, but they add no extra damage. Once the bonus is full, save your remaining resources.
Move the alliance close to the trap
Keep the assembly marker away from the trap during preparation. About 5 minutes before kickoff, move it directly beside the trap and have members teleport around it. Shorter marches mean troops return to the fight sooner.
Enable Offline Join
Turn on Offline Join and leave a strong formation set before logging off. When a rally still has open slots with 20 seconds remaining, Offline Join automatically sends your highest-Might troops so you can keep contributing while away.
Get more damage from every rally
Fill the strongest leader queues first
Rally leaders provide a damage bonus: +5% for R5 and officials, and +2.5% for R4. Prioritize those rallies when assigning members.
Match a pure march to the boss weakness
An all-cavalry or all-infantry march gains a hidden 15% damage multiplier when the boss is weak to that troop type. Use the matching type throughout the march to trigger the bonus.
Rotate two lineups
- Launch lineup 1 and prepare lineup 2.
- As soon as lineup 2 marches, speed up the recall of lineup 1.
- Requeue lineup 1 and repeat the rotation to keep attacks moving.
Coordinate around your top damage dealer
The doctor who deals the most damage receives 1 to 10 times the alliance rewards. If one account is clearly ahead, prioritize rally slots for that player to make the most of the reward multiplier.
