Onwin is a 5-star support tower based on Erwin Smith from the anime Attack on Titan. He increases the damage of units within his range with a manual ability (called Shinzou Wo Sasageyo) by a specific percentage, which is shown as Erwin's damage stat. This ability’s effect lasts 30 seconds and has a 60 second cooldown. Erwin does NOT directly attack troops and cannot be used on his own. Erwin is only obtainable from the Hero Summon and is not a part of any evolution.
