 * Blood Frenzy (all levels). If blood has been spilled on the battlefield, you can enter a blood frenzy as a bonus action on your turn. Your blood frenzy lasts for 1 minute. It ends early if you are knocked unconscious or if your turn ends and you haven't attacked a hostile creature since your last turn or taken damage since then. You can also end your blood frenzy on your turn as a bonus action. You can only enter a blood frenzy once before taking a long rest. Each level gains you a blood frenzy before needing to rest, beginning at level 3. Levels 3-6 are +3, levels 7-10 are +5, levels 11-14 are +7, levels 15-18 are +9, level 19 is + 12, and at level 20 your blood frenzy is unlimited. While in a blood frenzy, you gain the following traits:
 * For every successful attack you make, your HP increases by 1. For critical hits, your HP increases by 5. These temporary hit points are lost once the blood frenzy wears off.
 * You are vulnerable to blood magic. You take 1d6 of extra damage from blood magic, and have disadvantage on saving throws against being controlled through blood magic.
 * You have advantage on Constitution checks and Constitution saving throws.
 * When you make a melee weapon attack using Strength, you gain a bonus to the damage roll that increases as you gain levels.

On subsequent turns, you can use your action to extend the duration of this effect on the frightened creature until the end of your next turn.
