Bestiary Entry
Spirit of a disembodied dungeon denizen, corrupted by the touch of the Void. Most Wisps tend to stick to their chaotic maw hives, but occasionally, they are known to operate by themselves. Dissonance Wisps are utterly fatal when they get into close range, but otherwise can be easily outran. Avoid their charges at all costs.
