Defiant Devour (Gnolls/Free Gnolls only)

As a Gnoll, your kind has been beaten down, used as mindless pawns by unholy forces that curse you to always hunger, and starve. Made to suffer in the name of a horrid Demon lord, told that your kind are just hyenas that feasted upon the scraps left by fiends, and forced to always be on the move, or risk some adventurers trying to exterminate your kind in it's entirety, even if you aren't a barbarian, your rage burns bright within. Now free of demonic influence, you have learned to weaponize your curses against foes. Through training, meditation, pure spite, and unbreakable resolve, you have learned to channel all of the demonic energy in your soul through your fangs, allowing you to accomplish things thought impossible. You gain the following benefits:

-Your Strength, or Constitution score increases by one.

-Your fangs are now considered magical for the purpose of overcoming resistances. 

-When you successfully bite a creature, you may choose to channel your spite to bite into their very soul. When you do, that creature must succeed on a Constitution saving throw, (DC 8 + your Constitution modifier + your proficiency bonus) or take additional necrotic damage equal to your Constitution Modifier, and have their health reduced by an amount equal to your constitution modifier. You can use this ability a number of times equal to your Constitution Modifier, and regain all expended uses after a Long rest.
