I did a duergar-light not to long ago. mana regen + empire was awesome for mana issues with a duergar. Evade is sick. Full cloth armor for max HP/MANA and i was evading like crazy. Spared with someone and evaded disarm/trip at least 8 times in roughly 30-35 rounds. No i dont remember exactly but we both made comments about it firing off at every turn.

Downfall to light armor build: You depend 100% on mana. I couldn't kill an NPC to save my life and dont even try to retrieve by yourself. When your weapon hits for MUTILATES at best because you have a 10 dam roll...suck.

Perks: LOT a HP/MANA - you can tank all day long - spamming heal on yourself with the damage redux shamans + preps gives is OP! but again, you cant kill time. Your a GREAT support roll char. stand in the back and spam plague, poison, etc... on everyone. Just dont try to do offense and defense together. you will spend more mana than you can regen and then your just a waste of space in the room.

i'll see if i have any logs to give you an idea.
