Defender lvl 4 is an item held in the pocket slot while playing Barbarian Assault. It shows a player's defender level by creating a blue circle around them and three vertical gold bars with one horizontal gold bar above the others symbolizing 4. It cannot be removed or interacted with in any way besides examining it. When a game of Barbarian Assault finishes, the icon is removed.
Having level 4 in the Defender role increases the range in which penance monsters search for food.
