Superior Wish

These geniekin have worked hard to improve their magic, and through their dedication, have learned to cast the most powerful of all spells: wish.

Prerequisite(s): Geniekin, 16th level

Benefit(s): You gain the ability to cast wish once per day, though you can only cast it when another creature asks for a wish. When a creature asks you for a wish, you can cast wish as a reaction in order to grant the wish. The stress of casting this spell to produce any effect other than duplicating another spell still weakens you as per the wish spell, and you still have the 33% chance of never being able to cast wish again if you do this.
