Raging Bloodlust

When you reach a a third of your total maximum hit points, you must use your reaction to immediately enter a raging bloodlust. In addition, while in your bloodlust, upon drawing first blood from an enemy, you must make a WIS saving throw (DC 13), on a failed save you are overcome with the need to consume the blood of the creature.

Once you have raged the number of times shown for your barbarian level in the Rages column of the Barbarian table, you must finish a long rest before you can rage again.
