Hints:
1. I'm quite the survivor, with only one way to kill me in one shot. But even so, that particular brew is difficult to acquire, since it's impossible to get from the Bazaar. Quite expensive too.
2. A rather mischievous little gremlin, I like tinkering with the element of order just to tick those elementals off. After all, why not use one of their signature powers in erratic ways? Creativity!
3. Even the other field is affected by my wide range of mischievousness, only those pesky immortal creeps can escape my tinkering grasp.
