It does appear that I would have to venture into the Steps of Torment again to finish a quest. Afterwards, I would have to explore the Bastion of Chaos for another and finally, Port Valbury for the last. Then, I can move into the Ultimate difficulty of the game. Hmm.. Should I go straight into Ultimate?
Finally, I would need to restore my reputation with the Black Legion as the Outcast quests reduce Black Legion reputation.
