You cover yourself in an illusion that makes you appear to be on fire. Small flames lick and flicker along your limbs and features. You have advantage on the next Charisma (Intimidation) check you make against a Beast or Humanoid before the spell ends. Once you have used this spell to give yourself advantage on a Charisma (Intimidation) check against a creature, you can’t use this spell in this way against that creature again until that creature finishes a long rest.
