[Then again, perhaps it would be much more difficult to do without the benefit of water-breathing magic. Maria tries to get a good grip on the closest chest, but barnacles have grown over it, keeping it stuck tight. She glances over her shoulder at Scorpia, then down to her...claw-like armor pieces she wears over her hands. (That has to be what they are, right?) Hmm.]

Do you mind giving this a try...?
