Well first trap the stairs first. And I had all my guys besides a mage (I had my dwarfy dude shooting his special stuff for his crossbow - and I'm sorry I can't think of his name currently) and I also kept conjuring stuff, by the time he went demi lich, he only did 1 imprisonment and that was to an invisble stalker and then he was killed.

Also, What I find wierd is that Kangaxx appears right next to his tome, but the other liches appear at the far left of their tomes, why's that?

If your invisible stalker is imprisoned you should cast freedom there because if you don't when you go to summon more you will be able to summon 1 less since the 1st is imprisoned

Ring of the Ram + 2nd Ring of the Ram (the semi-cheezy one) + enraged Beserker with Mace of Disruption = a VERY scared demi-lich.

Protection from Undead doesn't work when he is demi-lich AFAIK (at least not for me) i don't know know exactly if it works on his lich form. You can fight him with 1 party member who is protected from magic and place the rest of them near the entrance so Kangaxx won't notice them.

Welcome to IW!!!!

Protection from Undead scrolls do work. Unless you have the Improved Kangaxx or something.
