I'm srry to make you guys feel bad but the oblivion cutscene is fake because if you watch Xration's video he is the person to "get" oblivion but if you watch it before he rolls it doesn't show that he uses an oblivion potion so the oblivion aura is unknown and the cutscene was fanmade and nobody has the oblivion aura 😢
I think you probably can. Maybe it’s just like an undefined situation where it shows question marks or something different instead of the rarity. I do know the aura gives a global message though and it’s a bit different than other auras, it says “________ has discovered THE TRUTH”
