You can use your action to unleash the darkness inside Zariel's Heart, causing your eyes to turn into pools of darkness and skeletal, shadowy wings to sprout from your back. Your transformation lasts for 1 minute or until you end it as a bonus action. During it, once on each of your turns, you can deal 1d6 extra necrotic damage to one target when you deal damage to it with your hexblade. You also gains a flying speed of 30 feet for the duration.

Notes: Damage: Necrotic
