Ok, here is the easiest way to defeat Kangaxx no matter what class you are. The biggest problem is twofold, he has True Sight and unlimited Imprisonment. What this means is that regardless of party size and composition, you need to be able to counteract these two threats.

For whatever reason, Protection from Magic scrolls do not protect against Lich Imprisonment (perhaps its regarded as an innate, non-magical ability), so while Kangaxx is still in Lich form, the best thing to do is to engage at range with magic or items able to hit him (like the Sling of Everard, etc.). His Lich form is relatively easy to defeat even with one character, I've found that once he casts all his nasty spells like Gate, that as long as you are out of range he'll go after his Pit Fiend. Eventually, he'll just start coming after you and try to melee. Simply stay out of melee range and whittle him down.

Upon his demilich transformation, move any character that is weak at fighting to the stairs and out of the basement. Use your best fighters, and have them read Protection from Undead scrolls. Kangaxx will now ignore them and allow them to kill him at their leisure. He will eventually break morale and start zipping around, I find it easiest to "herd" him into the walkway that leads to his casket. You can then chop him up there.

The other option is to use Staff of the Magi and Cloak of Non-Detection. Become visible to initiate dialog, then go invisible and wait for the inevitable Timestop. You'll be invisible and Protected from Evil, so he will be unable to target spells (True Sight does not work against the Cloak), and you can wait out while he battles his Summon. When the Pit Fiend falls, let loose with Cloudkill. This is an easy way to kill the Lich, as you pop in and out of invisibility. Once he goes demi on you, just read the Protection from Undead scroll (if soloing a mage-type, also use oil of speed and Tenser's Transformation) for each character that will attack.

Any comments, corrections, or additions are welcome.
