Hey! I've played this game a thousand times already, and I still come up with ways to keep me interested. I like to play with out-of-the-box strategies. Some builds I've played recently, are:
-Solo sorcerer using only melee (from chill/ghoul touch, all the way to black blade of disaster). Tenser's is not even needed to chunk everything to pieces.
-6 sorcerers/bards spamming chromatic orbs at everything in sight.
-Daredevil: fighter/thief permanently blinded (cheesing HIS next to enemies). Used EEKeeper to give him a couple farsights and true sight. Proficiency in clubs.
-Barbarian/cleric (EEK, of course): more than 100% physical resistance in the end.
-A complete pacifist (0 kills). Cleric/mage with summons (skeletons, mordy swords, aerial servant, devas, planetars), CC (maze, imprison and others). Defending himself with sanctuary and others. Kicking butt non-lethally with his bare fist (even made Adalon unconscious). This was the most fun, hands down.
-A party with XAN as the tank. Robe of neutral archmagi, moonblade, couple rings of fire resistance. Raining fire on him while he "kicked butt" with stoneskin/mirror image.
-A character who NEVER rested. Mage level 1 dualed to thief. Relied on wands and HIS. -96 luck at his worst.
You get the idea. Please give me some out-of-the-box builds for me to try and keep milking this wonderful games.
