Alliance Center

“War is an extension of politics - only good diplomatic relations are able to guarantee the long-term development of a civilization. In the Alliance Center, you can find an alliance you wish to join and conquer the land with your allies. ”
Unlocked at: City Hall Lv.1?

The Alliance Center is the main building for to Help and get Help from your alliance members. When you press the Alliance Help button, your alliance members will see a "Hand" over this building in their city and when they press it, your remaining queue time will decrease. You can be helped with building upgrades, research, and troop healing. Troop training and gathering do not benefit from the alliance center.

Game Mechanics of Helping

The amount of time removed per help is 1% of the remaining time or 1 minute, whichever is greater. The amount can be increased by researching Together We Rise in the Alliance Technologies. At max level research, each help will be 1% or 3 minutes, whichever is greater. The Alliance Center starts at a maximum number of helps of 5 and that increases by 1 per additional level.

Some examples of how this works:

What's Being Helped	Alliance Center Level	Together We Rise Level	Time Saved
			1%	1 min
5-hour Research	Lv.4 (max 8 helps)	Lv.2 (1m +30s)	3m x8 = 24m	1.5m x8 = 12m
8-minute Healing	Lv.8 (max 12 helps)	Lv.2 (1m +30s)	4.8s x12 = 57.6s	1.5m x12 = 18m
2-day Building	Lv. 15 (max 19 helps)	Lv.5 (1m +120s)	28.8m x19 = 9h 7.2m	3m x19 = 57m
