This has been an extremely useful topic, playing through my second play of this game now.
Question for the group: What triggers main story events, level or renown?
On my second playthrough I am trying to slow down the story and get 100% completion, which means farming in the regular dungeons to kill adventurers. I've avoided taking the experience boost skill, but it seems like no matter what I try the game keeps advancing and the only human adventurers I have unlocked are the Fighter and Thief. I guess I should make myself a checklist of all the prison cutscenes to make sure I am killing enough of the right kind, but I have my party set to standby so Darx kills everything with either Hailstorm or Wild Dance anyway. I figured there was no point counting if there was no way for me to increase it anyway.
