With my character, I want to take the focus off of shapeshifting. So, not using it to spy on people, or fight. More like "Something surprised him, and poof! a bunny."

With the fortune power, I'm not sure how to put a limit on something as random as that.
One option could be that since phookas are generally benevolent, Puck has a large conscience. Cranky on the outside, but rather softhearted. He wouldn't want to get in fights, and if he did, wouldn't want to get anyone hurt.

Also, fixed my CS.
