Burnished Soul

Casting this spell is a strenuous effort in will power and moral fortitude. Upon casting, your speed immediately drops to zero and you levitate 50 ft up, glowing with an unearthly radiance. You must succeed dc 16 Wisdom Save to even begin; on a failure, the spell ends and you slowly fall to the ground, unharmed but mentally weak (your movement speed is halved and you can't take reactions until the end of your next turn).

On a success, however, you continue with the ultimate ritual; you choose one target within range and look deep into your past to find the ones who have wronged you. Come up with the number of people who have caused you major suffering in your lifetime (including the target if applicable), this will ultimately be determined by your backstory, the campaign, and the DM. With this spell, you permanently brand the target's soul with your pain and the suffering that these individuals have caused you, forgiving their actions yourself. For each of these wrongdoing individuals, a ghostly image appears around you and flies at the target who must make a Charisma Save against your spell save dc each time (the target cannot save against its own image if there is one). On a failed save, the target takes 9d8 psychic damage and permanently loses an ability or resistance/immunity for each image that hits it (the loss occurs before the damage), taking half as much damage and losing nothing on a successful save. (remember the target must make the save for every ghost)

After successfully casting the spell, the target's soul is burnished with your sorrow, and brands for each of the individuals you chose, appear on its skin (if it has skin); etched into mind and body. You however slowly fall to the ground with the radiance still about you, your body weakened but your soul freed from the strain of those painful memories and unforgiveness. You are incapacitated until the end of your next turn, and cannot cast this spell again for one month.
