Explored 2nd level a bit, but still no luck finding the ??? to get map. Watched another alliance take on the 2nd receptacle, they were doing well but there were alot more strays here and mages got some agro (never good). I was able to pick off a few strays for them and was surprised I never got hit by Empty Seed, so assuming it only hits those in pt/alliance that has claim on receptacle. The alliance made it thru w/ about half their people, the rest were dead or dying from strays and couldn't port in time.
Decided to try my technique on 2nd receptacle once area was reset. It was working well, however, when I pulled a stray to regain hit points, the receptacle regenerate health very quickly. So worked it back down below 1/2 life and ran out of shehei, so w/ out utsusemi I just backed off and headed for exit.
I'm going to stock up and try this again tonight after work. Will post more info later.
