I have just replayed the whole saga (- Siege of Dragonspear) with kensai/mage. This combo is probably the most devastating in the whole game. Yes, during most of the game you are squishy as fuck (because you can't wear armor, and you don't have any access to protection spells for most of the saga). Irritating, I know.
But...when you get to later levels, you will be an unstopabble killing machine. Improved Haste + Time Stop + Crom Fayr (+ another hammer whose name I forgot) will take care of most bad dudes. Should something survive, Keldorn (with his dispells) and Sarevok (who has a chance of instantly killing - and which is further incresed if you give him the Gythyanki sword) will chop him to pieces with their Greater Whirlwinds and Power Attacks. Ask Melissan (last boss) how much that hurts.
Speaking of mods, I used Unfinished Business, Banter pack (which adds dialoge and fixed some broken quests, such as the one with the Genie), and a few good ones that added content (Return to Brinlaw, Sellswords and Dungeon Crawl).
