Transmogrify

You attempt to contort a creature's body horrifically you see in range. The target makes a Constituton save or is cursed for the spell's duration. Constructs, oozes, and creatures without a physical body aren't affected. When you cast this spell, choose the curse's nature from the following options:

• You fuse the creature's body into a single writhing mass. While cursed, it's restrained.
• You cover the creature's eyes and ears with horns. The target's blinded and deafened.
• You bloat the creature with vitriolic toxins. While cursed, the target's poisoned, its speed halved, and if it's reduced to 0 hit points, it explodes, destroying the body and killing it instantly. When it explodes, a creature within 15ft of the target makes a Dexterity save, taking 7d6 acid damage on a failure or half as much on a success.
• You twist the creature's visage into a disgusting sight to behold. While cursed, any creature that starts its turn within 20ft of the target, or enters within 20ft of it for the first time and can see it must make a Wisdom save or be frightened of the target until the spell ends. A creature can repeat the save if it ends its turn out of sight to the target, becoming no longer frightened on a success.

Also, while cursed, the target takes 3d6 slashing damage at the start of each of its turns as the magic tears and twists its form. A Remove Curse spell of 5th or greater cast on the target ends the spell.
