I am currently at level 48 with one of my Myth wizards and am going after my new Orthrus spell. Why do we have to redo the whole labyrinth quest just to get to the boss to defeat for this new spell? We already did the quest......why must we have to complete it AGAIN to get the new spell? They used to make us redo the Labyrinth to get the obsidian chest and thank goodness they stopped that. The labyrinth is a tedious quest and I'm dreading repeating it to get my new spell. Anyone else have this issue?
Quite a few level 48 school quest require a visit to the Labyrinth, not just for conjurers.
Theurgist have to visit the dungeon as well in order to learn their rebirth spell.
Other wizards such as Sorcerers have to redo the entire Shairataki Temple in order to get to the Plague Oni in completing their school quest for Power Nova.
So, while annoying, it's nothing impossible to do.
