Ok, so Mentor Roulette contains extreme primals.

Mentor roulette is literally every party instance in the game; you can get T13 in mentor roulette.



Don't think it'll even let you do the roulette....

I don't have T13 access, but I have Mentor roulette access. It's like leveling roulette. It puts you in anything you have access to.
