If Davy Jones copied the ability of Namazu:
Give this sea monster a shoot action. A wave S wide and 2L long leaves the sea monster in one direction. Up to 2 masts of every ship in the path of the wave are eliminated. Eliminate one of this sea monster’s masts.
Would the ship he’s on be able to use the ability? Or would the text refering to a “Sea Monster” prevent the usage of the ability?
