Here are some important things to know about Friendly Battles:

Friendly Battles is an alliance feature to battle your other alliance members! Alliance members can invite other members to a Friendly Battle and select any Warzone, regardless of the Warzones unlocked by the players, they will all be available!

Keep in mind that there is no winning or losing anything whilst playing in Friendly Battles, such as medals, crates, badges, and gold.

Also, once the invite to a Friendly Battle is sent, all other buttons will be inactive, until someone accepts the battle the only other actions available will be to cancel the battle invite and to send messages inside the alliance chat.
