As far as Worren, other of my characters like him, have similar abilities. Trent, Levius, Derik, and one other, all specialize in an element/weapon combo. For Trent, it would be the size/weight/length manipulation of staffs and earth/metal manipulation. 

So for Worren, hr specialized in ninja weapons, and can use runes to summon them. 

For the character, it's actually a pretty well drawn out character. For the purposes of the tournament, I would probably limit it to just heating things instead of cooling them, provided there isn't a definitive level she can cool them too, because it can easy toe the line of ice creation and whatnot. As well as ask if there was any more enchantments she can use to avoid 'batmanning', which is essentially the act of pulling stuff out of your ass on the basis of 'there are others (s)he can use, but aren't listed.' The arena is really particular on knowing what all a character is capable of to avoid such situations. 

Outside of the tournament though, it would be a good character to have.
