Mystic Arcanum (Wish - The Genie)

Your patron bestows upon you the ability to cast one 9th-level spell from your class list without using a warlock spell slot. After you cast the spell in this way, you cannot do so again until you complete a long rest. (This variant specifically exists to permit Genie warlocks to see Wish on their Spells list, should they desire; in this case, their class feature MA9 should remain unselected or ignored).
