Flesh Eater

Something about forbidden flesh fills you with a vigor you never get from normal food. You gain the following benefits:

• Increase your Constitution score by 1, to a maximum of 20.
• You gain a bite attack that acts as a finesse weapon with which you have proficiency. This attack deals 1d6 piercing damage. If you already have a bite attack, its damage increases by one die size.
• When you reduce a creature to 0 hit points with a melee attack on your turn, you can use a bonus action to move up to half your speed and make a bite attack.
• At the end of a short or long rest during which you consume at least half a pound of flesh, you gain temporary hit points equal to 1/2 the Intelligence score of the creature whose flesh you have eaten (minimum 1 hit point).
