Alliance Hall is one of the core buildings in Last Asylum Plague. It unlocks at Sanctuary Level 6.
It allows you to join or create alliances and receive assists from alliance members for building upgrades, research, and unit training. Each assist removes the listed duration shown in the Alliance Hall’s details tab, up to the assist cap for that timer.
Allies can also march reinforcements to this building to help defend your city.
Notes:
- Alliance Hall is how you join or create an alliance. Alliance Help, Alliance Gifts, Alliance Shop, rallies, and Alliance Tech all require you to be in an alliance.
- Joining an alliance grants 300 Diamonds. If you join before Sanctuary Lv.8, you automatically relocate near the alliance leader.
- Once you are in an alliance, members can tap Help on your construction, research, and training timers. That is Alliance Help (Speedup Assists).
- The building panel shows two help stats: Speedup Assists (how many helps you can receive on one timer) and Speedup Assist Duration (seconds removed by each help).
- Base values come from the Alliance Hall level: 4 assists / 30s at Lv.1, scaling to 20 assists / 59s at Lv.30. Alliance tech Enhance Help adds extra duration on top (up to −300s at max).
- Allies can also send reinforcements to your Alliance Hall. Those troops defend your city until they return.
- Place from Sanctuary Lv.6 once Falcon Tower is Lv.1. After Alliance Hall Lv.6, each level requires the matching Sanctuary level.
- It is a 3×3 building with 4 survivor posts.
- You can set survivors in Alliance Hall to further boost Help Count and Help Durations.
