my instance is very similar - i was doing helhiem on single player when i was in the last room before hel herself. the shockwave guy, + the life leech guy, and all the little zombies somehow managed to corner me and kill me. when i ressed i ressed right in the middle of the entire pack and tried to fight my way through but without any combo meter it was hard to get them off of me. they must of killed me 25 times before i finally got out and killed them. after the battle my entire body was flashing red (a note that you should repair ) so i went back to aesir and repaired, and started back where i was and went on to kill hel without dying and i got my elite pants .
