You can manipulate your magical fragrances to alter your magic, granting you the following benefits.
Incense Casting
When you cast a Witch spell, you can burn a stick of incense to cast it without spell components. A Witch spell you cast in this way can't be affected by Counterspell. If the spell requires Material components that have a cost specified in the spell, you must burn incense of equal value. A block of incense is worth 2 GP and contains 10 sticks of incense, each worth 2 SP.
Perfumed Charisma
You can expend a spell slot as a Magic action to create and apply a magical perfume to yourself. For 1 hour, you have Advantage on all Charisma checks made to influence a creature within 5 feet of yourself.
