Gift of the Raven - Second Stage

Through your sacrifices, you have honed finer aspects and control of your new nature. You gain the following benefits:

• You can use an action to polymorph into a raven-humanoid hybrid. This form lasts for 10 minute or until you use a bonus action to revert. Your equipment melds into your form or is worn by it (your choice).
• While in hybrid form, you have a flying speed of 50 feet.
• When you transform, you gain 5 temporary hit points.
• If a creature has reduced an ally to 0 hit points within the current round, you gain Advantage on attacks made against this creature.
• You have sharp claws that you can use to make unarmed strikes. When you hit with it, the strike deals 1d6 + your Dexterity modifier slashing damage.
• You can use this feature once without penalty. Each additional use before finishing a long rest requires you to succeed on a DC 12 Constitution saving throw or suffer one level of exhaustion after reverting.
• You have vulnerability to damage from silvered weapons.
