Sweet merciful Arneson... NOooooo!
I just know i will party with one of those one day, and ill be blinded by this stupid spell, and the slow walking... oh god, the slow walking.
Honestly i consider this spell much worse than the Grease breath of the iron defender, wont they ever learn how to make a pet that doesnt screw things up?
The chances of this happening on the worst possible moments are always going to follow murphy's law.
