ok since torkal is still peering over the edge, use a shadow ball, to hit it, and mabey break the ground torkal is standing on. Next since it will be raining, there will be no way escape electricity so use a shock wave if torkal is on your floor, or a thunder if torkal is still up on top. then end by going over to the covered stair way and chill.

shadow ball ~ thunder wave / thunder ~ chill and go under covered stair way
