An Alliance Marshal may choose to build an Alliance HQ to unify the Alliance’s forces and strengthen their armies.
Alliance HQs have 21 levels (0-20). When first constructed, Alliance HQs will be at Level 3, but can be downgraded to zero by rival Alliances. The higher the Level of your Alliance HQ, the greater the bonuses will be.
Each upgrade Level gives your Alliance additional Dominance Points, increases your Dominance Bonus, and increases the bonuses you are able to receive from Alliance Tech.
Only Alliance Members that are full Alliance Members (not Trainees in Boot Camp) can visit their Alliance HQ.
