Actually, I don't think I've ever had a bad side affect of a Wild Surge. Seriously, the only thing mine does is cast heal with an area effect, or double damage to an enemy. But the two or three best I've ever had was with NRD along with Chromatic Orb, sounds like a waste I know, but I ended up electrocuting everyone in the area. Two others was a cow dropping onto someone's head, and my favorite... hit points doubled
