We recently did Caught in the Web which took three trie to complete. First time on Reaper 1 and we did finish barely but the completion bug kicked in and it didn't register a finish. The next two times on Elite which turned out to be harder.

First meeting with Lolth. On Reaper I think we wiped but resurrected ourselves near the region exit. Then I walked to the top of the ramp and shot Lolth carefree because she wasn't reacting. Once down to 0 hp we continued, never having seen the legs or hand. In the last fight we wiped a couple of times. Then we made a stand at the top near the exit. Christopher and Sophia's characters managed to kill all the small monsters there which wiped the portal guardians and opened the way out.

On the second run we also brought Lolth to zero but this time the exit didn't open so couldn't continue the adventure. Eventually we triggered her then fought the legs and ran away from the hand. On the final fight we couldn't quite manage to kill the portal guardians and stay alive. Lolth is pretty deadly and a good aim.

Third run went much like the second and we were stumped. Then Christopher and I went all the way to the far side of the island from Lolth. I snuck up closer to where I could see her and shot her without her reacting and brought her to zero. Once she's gone I don't think the portal guardians respawn so kill them all and exit.

Unless that was a glitch we can kill Lolth in the final fight by being at the farthest edge of the island opposite her.
