[Wish]

hellfire sword on someone who can last a few rounds mono e mono. flying shoes. script to attack large enemy monsters. (this is also how I took out an eat of the dead) if his magic resistance is too high, send in some cronie hold the banner of the northern star (or whatever its called) that lowers everyone's MR.

also if you have him fire at large monsters, he has a better chance of targeting the wyrm. make sure he is in range. (place him towards the front, maybe with a silver hauberk on to keep him from getting arrow'd)

you can work on getting rid of the spellcaster aspect of him by using a bow of beotulf instead of the ethereal crossbow.
