If I were to take a guess, I think the Fatty has something related to those tongues or his mouth. Perhaps a paralytic effect, or some special effect when he bites something? I'd best be careful and make sure I don't get hit. The Mage is a little trickier, but I wonder if she's accelerating her magic in some way. The speed her projectiles come out is way too quick, so fast I can't even dodge, and I know they're coming before she even shoots them!
