Stardust Cell Staff

The Stardust Cell Staff is a post-Plantera minion-summoning weapon that summons a Stardust Cell to fight on the player's behalf. It fires smaller versions of itself which stick to enemies for 10 damage per second, as well as charging into enemies for melee-style damage. Sometimes when killing a enemy that the cells are targeting the cells will despawn not sure if intentional or just a bug
