This is cute, just a clarification, does he summon the liquid metal from nowhere or does he turn metal INTO liquid? I'd say if it summons it from nothing, that's perfectly fine but if he carries some ACTUALY liquid metal around him, it could be easier to make it connect to his body or keep the corrosion from corroding so fast. NOT A REQUIREMENT TO TAKE, JUST A THINKY THINK ON MY END.

ITS FINE AS IS THOUGH.
