Old thread, but eh.

Recently did the Zodiac relic for my level 82 white mage.

Stone Vigil's redesign means it's pretty quick to get through, around 2:15-2:30 depending. Aside from having to turn around after the second boss, you don't stop running until the door before the final boss. On white mage this meant building lilies constantly, so I'd Swiftcast Glare -> Assize the first boss and one-shot the remaining bosses with Misery, with an additional Assize and Holy towards the end to clear the trash mobs before opening the boss door.

All that said, I've seen people claim Aurum Vale clear times in the 1:30 range, so if you can manage that, then so much the better. And Thornmarch or another Extreme trial will be fastest overall if you can reliably clear in 30 seconds and don't spend too much time between runs--unless one of the quick dungeons is on bonus, but even then it depends on how fast you can actually clear the quick dungeon in question.
