Range Heroes can only "effectively" attack enemies that are 2-5 cells away (displaying a non-broken arrow). If the enemy is outside of that range, only 50% damage will be dealt, (displaying a broken arrow). If enemy is in a nearby cell, range heroes can only melee attack and only deal 50% of damage.\n\nYou can view your units and enemy units movement range by tapping on the their character icons on the bottom left battle "Sequence Panel".
