Spiteful Duchess Patron

 You have made a pact with The Duchess herself, a shapechanging devil bound to Asmodeus. Known for her profound disdain for studious magic-users and her absolute mastery over space, secrets, and antimagic, The Duchess grants her favored mortals a mere fraction of her spiteful power. Warlocks bound to the Duchess excel at locking down enemy spellcasters, manipulating unbound darkness, and effortlessly folding space to their whims.

Level 3: Fiend Spells

The magic of your patron ensures you always have certain spells ready; when you reach a Warlock level specified in the Fiend Spells table, you thereafter always have the listed spells prepared.

Fiend Spells

Warlock Level	Spells
3	Magic Missile, Command, Darkness, Knock
5	Fireball, Slow
7	Compulsion, Confusion
9	Modify Memory, Dominate Person

Level 3: Spell Disdain

Channeling The Duchess signature spite toward traditional spellcasters, you can severely punish those who weave magic near you. When a creature you can see within 60 feet of you casts a spell, you can take a Reaction to force them to make a Wisdom saving throw against your Spell Save DC. On a failed save, the creature takes 1d10 Psychic damage. If the target is casting a spell using Intelligence as their spellcasting ability, the damage dice automatically becomes 2d10 out of sheer disdain.

Level 6: Casual Stroll

Once per turn, as a bonus action, you can teleport up to 30ft into any unoccupied space you can see
You can use this feature an equal number of times to your Charisma modifier per Long Rest. You regain all expended uses when you finish a Long Rest.

Unbound Shadows & Secrets

Your mind becomes an impenetrable fortress, and your shadows warp to your will. You gain Resistance to Psychic damage, and your thoughts cannot be read by telepathy or other divination means unless you allow it.

 

Level 14: Aura of Nullification

You manifest a localized, temporary version of The Duchess' anti-magic aura. As a Magic Action, you project a 15-foot-radius sphere of nullifying energy centered on yourself that lasts for 1 minute. For the duration:

• You and friendly creatures within the aura have Advantage on saving throws against spells and magical effects.

• You and friendly creatures within the aura have Resistance to damage from spells.

• Magical summons or familiars hostile to you that enter the aura or start their turn there must succeed on a Charisma saving throw against your Spell Save DC or be banished to their home plane.

You can only use this feature once per Long Rest
