Noble Ascension

You have risen to the full potential of a true Noble Genie, now commanding the power to bend reality to grant wishes to those who would earn your favor. Starting at 18th level, you learn the wish spell (or another sorcerer spell if you already know wish) and it does not count against your number of spells known. When you cast wish at the request of another creature, explicitly for the purpose of genuinely fulfilling their wish, you do not suffer any stress (as described in the spell). You can grant a wish in this way to to specific creature no more than three times in that creature's existence. When you grant a third wish to a creature, there is a 33 percent chance that you will be unable to grant wishes in this way again until a year has passed.

Additionally, if you lose the ability to cast wish (as described in the spell), you regain the ability to cast it after one year, but only in the way described by this feature.
