It got a lil hairy at times . . under 100 hp's twice . . . . Absolutely essential . . potions of speed!
Used 2 potions of speed, 4 of healing. Prep was: Stone Skin, shield scroll, speed potion, regeneration, 'port to Angolwen . . .ambushed!
Chain Lightning, then Corrosive Cloud enveloping the 2 farthest west archers, Phase door behind the east most sticking out tree, healing/attack archers for 2-3 rounds until urkuk showed up, speed allowed me to move away, then fire at him . . . .read scroll of phase door, ported to west end, chain lightning killed all but the eastern archers, more healing potions, killed the archers, then urkuk . . . .had to phase door away from him once, but once his minions were gone, he wasnt difficult.
Kudos to DG, the battle was difficult, but conquerable!
P.S. I was afraid of that .. . *sighs* lol
