Put other things besides communer supps into one neat package? Things that come to mind are certain assassin skills, transmuter spells, both classes having a big array of things to practice.

And also an idea for faerie fog. Transmuters get 'dimension hop' (name pending), which is linked to duo dimension in the way that, it shifts dimensions in the room for a second to bring out hiders, works just like faerie fog though.

Invokers would get 'spark sight' (name pending), which would charge a room with positive particles, whatever, and bring out any hiders with a jolt, no actual dam tho.
