True Enlightenment

You sit down and clear your mind of any obscenity. Entering a state of pure concentration. As you cast this spell, you spend the duration of the casting time quietly sitting.

While this spell is activated, you will have a +10 bonus to all skill checks, and saving throws you are proficient in. This bonus is doubles if you are expertised in that skill. You are also immuned to psychic damage and harmful mental effects. This cannot be removed by magical means.

After the spell duration is up, you need to make a Wisdom Saving Throw against your spell DC, on a failed save, you'll become stunned for 30 seconds and will be unable to cast spells for an hour.
