Armor (studded leather), legendary (requires attunement)

This beautiful black leather armor is covered in intricate scrollwork, and has a mantle bearing the black feathers of the Matron of Ravens. Legends say that it has been worn by a number of that deity’s champions over the centuries — most recently, Vax’ildan of Vox Machina.

Dormant. When the Deathwalker’s Ward is in a dormant state, you gain a +1 bonus to AC and you have advantage on death saving throws while wearing the armor.

Awakened. When the Deathwalker’s Ward reaches an awakened state, you gain the following benefits:

• The AC bonus of the armor increases to +2.
• While wearing the armor, you have resistance to one of the following damage types of your choice: acid, cold, fire, lightning, necrotic, or poison. You can change the damage type when you finish a short rest.

Exalted. When the Deathwalker’s Ward reaches an exalted state, you gain the following benefits:

• The AC bonus of the armor increases to +3.
• As a bonus action, you grow large black raven wings that grant you a flying speed of 60 feet and last for 1 hour. Once this property is used, it can’t be used again until you finish a long rest.
