Disfigure

This twisted spell can turn a creature into a mockery of themself. A creature targeted by this spell must make a Constitution saving throw, taking 10d10 necrotic damage on a failure, as well as suffering one of the following disfigurements:

• Crossed Arms: The target's arms are forcibly crossed across their chest, and meld into one another. The creature may not use their hands for anything.
• Scatter Face: The target's facial features fall off of their face, leaving only a blank, bald head. They are blinded, deafened, cannot speak, and have disadvantage on any Charisma-based checks.
• Rigor Mortis: The target's body immediately tenses up, and their joints tighten. Their Strength and Dexterity scores are both reduced to 6 if they are not already lower, and their maximum hitpoints are reduced by an amount equal to the damage dealt by this spell.
• Wings of Flesh and Bone: The target's shoulder blades extend, rupturing out of their back, and stretching into a set of macabre bone wings draped with flesh. These wings replace any wings the target might have already had. The target also gains a flying speed of 60.
• Stone Heart: The target's heart ceases to beat, and turns to stone. If the target lacks a heart, this effect fails. The target gains resistance to non-magical bludgeoning, piercing and slashing damage, as well as necrotic damage, though not the damage of this spell.
• Feral Distortion: The target's joints and limbs reconfigure, agonizingly shifting into new angles and sockets. If the target is not bipedal, this effect fails. Otherwise, the creature is stooped into a quadrupedal, hunched form, no longer possessing opposable thumbs, and their mouth becomes bestial, growing two saber-like fangs, which can grow back during a short rest if broken. The creature can no longer hold items in their hands, but gains a 20 foot increase to their walking speed, their Strength increases to 18 if not already higher, and they gain a Bite action, which they are proficient in and deals a d8 + Strength modifier piercing damage on a hit. The attack and damage modifier of the Bite are based on Strength.
• Countless Eyes: The target grows eyes on every exposed surface of skin on their body. They gain truesight out to 60 feet, can no longer be surprised, and have advantage on Wisdom (Perception) checks which rely on sight.

On a successful save, the damage is reduced to half and no disfigurement occurs. A creature may willingly fail this save. A creature killed by the damage of this spell suffers the disfigurement, whether their save was successful or not.
