Unholy Majesty

You transform into a majestic and terrifying fiendish entity, gaining the following benefits for the duration:

• Fiendish Resilience: You gain resistance to cold, necrotic, and poison damage.
• Dark Aura: Your presence emanates an aura that extends 10 feet from you. Creatures of your choice within this aura have disadvantage on saving throws against being frightened or charmed.
• Enhanced Physicality: You gain temporary hit points equal to twice your warlock level. Your Strength, Dexterity, and Constitution scores each increase by 2 for the duration. These increases can’t exceed 20.

At 15th level:

• Enhanced Resilience: You gain resistance to acid and thunder damage.
• Dark Majesty: Your Frightful Presence now affects creatures within 30 feet of you, and the frightened condition lasts for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

At 20th level:

• Dreadful Majesty: As an action, you can assume the form of a powerful demon or fiend. For 1 minute, you gain the following additional benefits:
  • Fiendish Form: Your appearance becomes more demonic, and you gain a flying speed of 60 feet.
  • Enhanced Resistance: You gain resistance to bludgeoning, piercing, and slashing damage from non-magical attacks.
  • Demonic Charisma: You gain a +4 bonus to Charisma (this bonus is in addition to any other effects that may increase your Charisma score).

After using this feature, you must finish a long rest before you can use it again.
