(After Polterghast has been defeated)

The Deep Sea Dumbbell is a post-Moon Lord rogue weapon that drops from Reaper Sharks after Polterghast has been defeated. When used, it throws a dark blue dumbbell that is not affected by gravity and bounces twice off of tiles or enemies, breaking on the third impact. Every time it bounces, it releases 2 smaller gravity-affected blue weights which fly out in random directions and velocities. The weights break upon contact with enemies or tiles, and only deal 25% of the weapon's base damage. The main dumbbell and the weights both inflict the Crush Depth debuff for 10 seconds upon contact with enemies.

Right-clicking with the weapon will cause the player to lift it into the air as if flexing, increasing the damage of the next attack from this weapon by 100%. Four flexes are required to reach the maximum damage boost of +400% (5x).

Its best modifier is Flawless.



  • A dumbbell is a type of free weight that is often used in exercise and weight training.
  • This weapon is a reference to the bulky arms that the Reaper Shark sprite has.
