Hmm... I think I would be a mercury adept, with mostly support and healing psynergy, but I can still pack a punch with my attack psynergies too.
My weapon would be a long, thin sword made completely of razor sharp ice, much like the sword Sephiroth carries just alittle thicker, (if anyone here has played Final Fantasy) and like 5 feet long instead of 7. lol. The handle has the water in it, and I use it to make the sword when I need to draw it, like a light sabre from Star Wars!
lmao. That was fun.
