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, and also reduce enemies' defense by 15 if it was above 0.

Right-clicking with the weapon will cause the player to lift it into the air as if flexing, increasing the damage of the next stealth strike from this weapon by 100%. Seven flexes are required to reach the maximum damage boost of +650% (7.5x). If the dumbbell contacts an enemy directly while it is held up, the enemy will take +2400% (25x) the weapon's damage.

Its best modifier is Flawless.
