Undead Siege is an alliance defense event in Last Asylum: Plague. Once unlocked and started, it sends waves of Blights to attack every eligible alliance member.
How Undead Siege works
- Expect 20 waves. Each wave becomes harder, with overall strength determined by the selected difficulty. The first run is expected to be very easy.
- Defeat waves to earn points. Successful defenses contribute to your event score.
- A failed defense eliminates you. Once your Sanctuary fails to defeat a wave, you are eliminated from the event.
Pair up to improve personal and alliance points
A recommended approach is to exchange reinforcements with an alliance member of similar strength, then spread your remaining marches across other allies.
- Choose a partner of roughly equal strength. Compare Sanctuary level, troop tier, and the Might of your primary march.
- Exchange your strongest marches. Send your main march to reinforce your partner, and have them send their main march to reinforce you.
- Spread out your remaining marches. Reinforce other alliance members, preferably those around the same troop tier.
- Coordinate before the waves begin. Make sure your partner is reinforcing your Sanctuary before committing your main march elsewhere.
Why reinforce several allies?
The aim is to keep your Sanctuary defended while giving your marches opportunities to earn points at several allied Sanctuaries.
Under the reported scoring behavior, your partner defeats the waves sent to your Sanctuary, preserving your own wave rewards, while your deployed marches can earn points for waves defeated at the Sanctuaries they reinforce.
Reinforcement scoring still needs confirmation: each defending army is expected to earn points for successful waves at the Sanctuary it reinforces. Check battle reports and event scores during the opening waves to confirm how points are credited.
Before the Undead Siege begins
Find a similar-strength partner, exchange main marches, and spread your other marches among allies. The goal is to survive as many waves as possible together and improve both personal and alliance scores.
