I recently did BG + ToB through with a kensai + party. My kensai sure did die a lot, but man, he *really* could swing a sword! I had Sarevok, Keldorn, Aerie, Imoen and Cernd.. and with this 6 character party, my dual-katana kensai had approximately 50% of all kills!
One bit of advice that I can give you is that you should take a thief into your party for a little while, let him/her take a few potions of master thievery to pickpocket Ribald Barteman in the Adventurer's Mart for the Ring of Regeneration. You're gonna need it!
Hyvä aikan!
