I was reading another post about killing Drizzt, but you can pick pocket his swords from him fairly easily. Imoen is useful for this as long as you have a couple levels, save and steal, when you get one sword save and try for the other. But yeah, they're great swords..worth killing him if you have to, the +5 one made my fighter/mage pop guys like you wouldnt believe.
I'm pretty sure you can only pickpocket one of the scimitars from him... for the other one you'll have to kill him because he's holding it in his hand.

You can pickpocket the frostband. for the defender you have to kill him.
But killing Drizzt isn;t to hard if you uses a cheesy tactic.
(See "how the H*** do you kill drizzt" post by Minime)
You can steal them both...At least you can in the first version, maybe they changed it with a patch or something. When I played it first I didn't have any patches and stole them both but you cant steal his armour. Still the Defender +5 is a awesome weapon and I used that with a fighter mage all the way through TOSC.
