The Seven Seas Devastator is a craftable post-Moon Lord flail. It releases bubble projectiles along the length of its extension; the longer it extends, the more bubbles will be produced. These bubbles will pass through tiles and home towards enemies, not dissipating until contacting an enemy or after three seconds. Each bubble grants a life shield to the player when striking an enemy, providing them with additional temporary maximum life that stacks with successive bubble strikes up to a limit and decays over time. The flail head will also create a blue explosion upon directly contacting an enemy, which will deal area of effect damage, and the flail itself has a very high velocity.

The flail head can be extended up to 34 tiles before returning. As it is a 'launched' flail rather than a 'thrown' one, it cannot be flailed around as you walk, immediately disappearing upon its return. It works very similarly to the Flairon.

Its best modifier is Godly.
