Shellfish Staff

The Shellfish Staff is a Hardmode summon weapon that drops from the Giant Clam mini boss. It summons a Shellfish that follows the player and attacks nearby enemies by attaching itself to them. Each Shellfish takes up 2 minion slots. Shellfish only deal direct damage when initially latching onto an enemy. From there, it inflicts the Shellfish Claps debuff for as long as it remains attached to the enemy. This debuff deals a total of 125 damage per second for every shellfish attached to an enemy. Up to a max of 5 shellfish can cling to an enemy, causing 625 damage every second.

Tips

 * Because this weapon deals damage via a debuff, it is unaffected by the summon damage penalty.

Trivia

 * The Shellfish Claps debuff ticks twice as fast as most other debuffs: 10 times per second instead of 5.
