Specter's Nature

You have developed traits similar to those of a specter, granting you the following benefits:

• You gain resistance to necrotic or poison damage (your choice).
• As a bonus action, you can become incorporeal, until the start of your next turn. While you are incorporeal, you gain a flying speed equal to your walking speed, you can hover, and you can move through other creatures and objects as if they were difficult terrain. You take 1d10 force damage if you end your turn inside an object. You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
