Discerning the spell in a very strong wilderness room.

BES
To begin to be able to cast this spell, you will need to reach the rank of a 32nd degree adept. By the time you have mastered this spell, you will be ranked as a distinguished grand master in your abilities as a caster. It requires the Augmentation and Warding skills to cast effectively.

CS
To begin to be able to cast this spell, you will need to reach the rank of a 32nd degree adept. By the time you have mastered this spell, you will be ranked as a master in your abilities as a caster. It requires the Augmentation and Warding skills to cast effectively.

32nd degree adept is 232. I would say the previous poster was accurate if feats are accounted for when discerning spells. If discern doesn't take feats into account, you may be able to successfully cast it with feats before 200 ranks.
