krissy, just kill him afterwards: there'll be a bonfire after the fog door giving you a mostly silver knight free path to run through between attempts. bring some healing miracles if you have any. you can blow up the sorcerer in a few attacks, backstab the spear guy when he charges at you like a fool, and try and land a riposte on mister dual-wield. he's got a red tearstone ring on, so be on your guard if he hits critical health.
