Embassy

"A facility that allows you to send and receive reinforcements."

The Embassy is a building in your courtyard. The information says:

'''Embassy is a facility that allows your allies to send you reinforcements and help you speed up in various scenarios. Upgrade Embassy to improve reinforcement cap and help efficiency.'''

So, this building provides two quite different boosts:


 * reinforcement capacity, and
 * Alliance help attempts and efficiency.

Reinforcement Capacity
This is a measure of how many troops belonging to other players in your Alliance can be sent to you to reinforce you. The higher the reinforcement capacity, the more likely your territory is to withstand attacks.

You begin with zero capacity until you have built your Embassy (Level 1). This means that no one can reinforce your territory in the event of attack. (Building your Embassy is a part of the tutorial.) When maxed out at Lv. 40, the reinforcement capacity is 1,200,000 troops.

Alliance Help
When you request speedup help from your team mates (Alliance Help), only a certain number of them can respond for any given task. This is the "speedup help cap". This cap is governed by the level of your Embassy. Upgrade your Embassy to increase the number of help attempts you can recieve.

Additionally, the quality (or "efficiency") of the help provided is improved by upgrading your Embassy. Click on the Information icon (top right) to see the efficiency boosts list.

You begin with 2 attempts until you have built your Embassy (Level 1). This means that only two team mates can respond to your requests for speedup help. When maxed out at Lv. 25, the speedup help cap is 28. Further upgrades to the Embassy have no effect on this cap, however every upgrade to the Embassy improves the efficiency of the help response (and is therefore worthwhile).
