To be totally honest, I don't think I have ever used Fatty's ability. I have always just used him for his defensive stats which are actually pretty good, especially for a low threat hobbit(koff koff Bilbo). I'm kinda sad about this because I always liked Fatty as a character and it's a real bummer that Folco Boffin is amazing while Fatty's ability is awful. I hope they come out with a new version of Fatty eventually or errata this one to improve it(or both!).
