[@Dealdric] I haven't played D&D personally, but I get ya. :3

Hmm, I think it's all interesting, but I don't want to give your character a huge advantage over the others. It won't do to just "get Aquarious to do it" any time a difficult situation comes up, haha.

I'll give you underwater breathing and lightning breath, as I can't see those tipping the scales much. Shapeshifting might be too convenient, though. How about just one alternate form aside from the true form?
