The Stardust Mothercell Staff is a Hardmodesentry summon weapon that summons an Stardust Mothercell that shoots fast homing stardust energy projectiles nearby enemies. Only one stardust mothercell can be summoned at a time.
Its best modifier is Ruthless. The Mythical modifier provides the widest array of stats bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, Minions cannot deal critical hits. The only significant advantage a Mythical Stardust Mothercell Staff has over a Ruthless one is knockback.
