Ghostly Magic

your soul is especially powerful, and you may channel its power into a semblance of mortal magic. Each day, you may cast up to three of the following spells: Blink, Catapult, charm person, fear, and invisibility(self only). You regain the ability to cast these spells when you finish a long rest.

when you take this feat, choose either Charisma or Wisdom as your Spell-casting ability for these spells, and you cast any spells gained by this feat at their lowest possible levels.
