The south map portion lists Doom Lord Septimus fight with an error stating that he is best pulled with a pet cuz the doors are locked. If you do in fact fight him from behind the door its shuts during the fight and you cannot continue to the last boss. Everything about spawning him is correct, just the pull with a pet thing can lose you disco aa and and another named kill/loot/aa due to the door lockout.
Im new to posting here so sorry if I rambled or did this incorrect let me know, if you do use the info and want to credit me.....
