War Horn is an item which have a chance to drop after successfully defending an Item Island.
The War Horn can be given to your commanders in order to give them the ability to immediately call soldiers form a house of your choosing on an island. Level 1 War Hornl calls 3 soldiers and can only be used once per island. After being upgraded to level 2 (8 coins), 5 soldiers are called instead of 3. Units cannot be reinforced above their limit of 9 soldiers. At level 3 (14 Coins) the War Horn gains the ability to be used twice an island, after a few seconds cooldown.
As with every item in the game, once it is assigned to a commander, it cannot be removed anymore. You can choose War Horn as a starting item once you have unlocked it.
- Usually not as impactful as some other items. And it's effect alone doesn't seem to be really good on any unit. Eventhough, it's better to know that War horn seem to work best for Infantry
- Since your commander is invulnerable until the last unit falls, calling troops from a safe house and lead them to a safe spot can prevent your commander from certain death.
