The Alliance tower is a tower that is located next to your Troop Academy, and your Throne Room. With your Alliance Tower you can:
- Join an Alliance
- Create an Alliance
- Join Alliance Wars
- See War Season History of Alliance Wars
- Donate gold to your alliance and see how much gold other members have donated
- Chat with other Alliance members
- View the Elite Boosts
- Request and donate Insta-Troops
- Have Ninjas/Zombies/Yetis in Defense
Donating
You can donate to your Alliance in the Alliance Tower. The standard donation is 1K, but when you upgrade your Alliance Tower, the donation limit will be increased. After donating, there is a cooldown of 24 hours before you can donate again. From the Alliance's gold, the Alliance's leader can buy eliteboosts or upgrade the alliance. If your Alliance Tower is upgraded, the 24 hours donation cooldown timer resets. When you can donate, a yellow light comes out of the Alliance Tower.
Elite Boosts
Elite Boosts are enhancements that upgrade defense buildings, or units. They mostly get a huge increase of health, and some other special power. New eliteboosts are unlocked as your Alliance's level gets higher.
The owner of an alliance can purchase eliteboosts from the alliance's gold. Only the leader and generals can use the alliance gold for it, and if there is not enough gold, no eliteboost can be activated. All players can pay real money to activate an eliteboost. The gold that's left, will be transported into the alliance's gold storage. Eliteboosts only last for a few hours, but they can be extendend the same way as they're activated.

Extra Donation Costs
Aside from regular donations, players can make larger donations by spending real money on their alliance. Extra donations are often made by alliance leaders who want to invest in their alliance. Players can do the same, but have less incentive to do so if an alliance is impersonal and they can be kicked at any time.
Depending on their alliance tower's level, extra donations become bigger and more expensive, but also more cost effective. The number of extra donations isn't limited by the game.
Extra donation costs depend on a player's currency and may change over time due to price changes, handling fees, and currency fluctuations.
You can skip the recovery time of 24h by paying 100 gems.
Gem Donation Costs
If you have spent real money in-game to buy gems, you'll get a new option on the donation tab that will allow you to donate gold to your alliance by spending gems. How much you can donate by gems depends on your alliance tower level.
