You can get them to baal easily
All you need is to cast stone skin/divine armor + teleport on round 1. As a paladin or warrior, stone skin/divine armor on round 1 is a must, so it will have to take one more turn to get to baal with them.
In the Champion of the arena mini-campaign, I found teleport to be a wickedly overpowered and downright amazing spell on a vast humber of occasions, well worth having it.
