You can cast the wish spell without expending a spell slot or requiring any components. In addition, you suffer no stress when casting the wish spell to produce an alternative or greater effect, though you must cast it on behalf of another creature when using the spell this way. You have great latitude in how such a wish is granted and nothing prevents you from twisting another's wish for personal gain. Charisma is your spellcasting ability for this spell.

If you cast this spell to produce an alternative or greater effect, you can't cast it again until 90 days have passed. Otherwise, you can't cast it again until you finish a long rest.
