what should i do with kangaxx? i kill him and then he becomes a demi-lich and he is nearly invincible! not even the daystar can hurt him. any suggestions?

1. Turn Undead
2. Daystars Sunray ability
3. Melf Minute Metors.

Buy a Protection From Magic scroll, a +4 weapon and give them both to your best fighter.

hey Memmnoch do you have ICQ or AIM?

Casts Spell Immunity = Abjuration. Then waddle in and serve as a Imprisonment basket whilst your fighter goes in from behind and whacks at it. (The mage can also fight with Melf's Minute meteors)

PS - Prot. From magic can be bought at Adventurer's Mart.

Do you have any berserkers in your party? If yes, give him a +4 or better weapon (e.g. Crom Faeyr, War Blade, Carsomyr ...etc), enrage him (before the imprisonment spell kicks in), and hack away. Or since the demi-lich can only focus on one target at a time, enrage the berserker and have him in front of the demi-lich's face. The lich will just keep casting imprisonment on the berserker, your party members can now hack away with leisure (provided the enrage is well timed and not run out ).

If not, then summon a fire elemental, cast protection from magic energy, and let it go at it.

Either way, have all your other party members away and out of sight of the demi-lich. There are many other strategies to kill the demi-lich, these are just a few. Good luck.
