Sanctum: Sacred Mirror Major Boon suggestion

I suggest to make it possible to obtain only on the 3rd floor+. Everyone's playing sanctum because of divine orbs and mirrors, no one wants to duplicate some alterations or whatever. Sad that I can't remove it with an affliction like I can with minor boons.
Or make divines and mirrors appear on the 1st+ floor.

Bump.
Thx for this major boon on the first floor, very useful (no). Another stolen 50% max resolve (yes). Another stolen opportunity to duplicate something useful in this run (yes).
upd. corrupted empty run
