The Poseidon's Charge is a Hardmode spear that is dropped by the Submerged Mimic. When swung using right-click, it will launch a stream of bubble projectiles that briefly linger to deal damage, and receives added autoswing, at the cost of decreased base damage.
Its best modifier is Godly.
- The Poseidon's Charge is named after Poseidon, the Greek God of the Sea.
- The Neptune's Grasp, another drop from the Submerged Mimic, is named after the Roman equivalent of the same God.
