Gift of the Raven (Stage 1)

You have learned the fundamentals 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 1 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 30 feet.
• 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.
