The Fuel Cell Bundle is a Hardmodesummon weapon that drops from The Plaguebringer Goliath. When used, it throws a small gravity-affected flask that deals no contact damage, but summons a small and armed miniature Plaguebringer minion upon tile contact. Plaguebringer minions stay at a certain distance from enemies to rapidly fires explosive missiles that inflict the Plaguedebuff. Occasionally, a homing variant of the explosive plague missile is fired.
Its best modifier is Ruthless. The Mythical modifier provides the widest array of stat bonuses, but these primarily affect the initial summon rather than the resulting minion. Additionally, minions cannot deal critical hits. The only lasting advantage a Mythical Fuel Cell Bundle has over a Ruthless one is knockback.
