This has nothing to do with the argument about killing drizzt, but just so you know; an easier way to waste that drow would be to take the potions that the vendor sells you in the nashkel fairgrounds (the ones that set one stat to 25, while setting another to 3); take the one that sets your str to 25, give it to your thief who has a shortsword and backstab drizzt (this would be imoen in my party). 2 out of 3 times this will kill drizzt, and it will chunk him on a critical - this is due to a bug on how bg1 calculates backstab damage (they take into account the damage bonus from str when adding the multiplier). This technique also works on Sarevok
