The wizard can conjure up boxes to begin with and levitate objects, which I admit are not the most awe - inspiring magical skills, but are still damn handy; The rogue has a bow with a variety of unlockable arrow types and can attach a rope to
pieces of scenery so that she can swing through the environment, making her agile and dangerous.
This can sometimes lead to frustrating situations where you get jammed into a
piece of scenery and can't escape, but the maps are designed
so that there's almost always somewhere to go, and good spatial awareness is rewarded.
