Path of the Blood Scourge

“The primal nature of hunger forces creatures to evolve in an infinite number of ways. Your hunger for blood turns you into a creature that not only subsists off of it, but allows you to shape your own body into a walking mass of ooze-like blood. This power makes you into an apex hunter, creating monuments to your ravenous addiction to the life flowing through the veins of your victims.”

Creature of Slaughter

 Starting at 3rd level, your body becomes little more than a facsimile of life, meant to act as a vessel to contain blood. You gain the ability to alter your appearance at will as an action, following the shapeshifting rules that changelings adhere to. You also cannot regain hit points from spells that restore HP or Class features, such as a paladin's lay on hands.

Appalling Appetizer

Starting at 3rd level, whenever you rage, your attacks become vicious enough to paint yourself and your surroundings red. Whenever you hit a living creature that possesses blood with a melee attack and are within 5 feet of the creature, their blood splatters onto you, healing you by an amount equal to half the damage you deal to them.

Blood Trail

Starting at 6th level, you have advantage on wisdom [perception] checks and Intelligence [Investigation] checks to track and locate creatures with less than their maximum hit points. During a rage, you can dash as a bonus action, but only towards a creature with less than its maximum amount of hit points that you can see.

Blood Bath

At 10th level, whenever you reduce a living creature with blood to zero HP, you can use a bonus action to turn their body into a fountain of blood that showers down on a 10 foot radius around it for the next minute. Whenever you start your turn within this radius, you gain a +1 bonus to attack and damage rolls. This bonus stacks based on how long you stand within the radius, to a maximum of +10. At the start of each turn, this bonus decays by one, as long as you remain outside of the blood fountain radius.

Blood Beast

At 14th level, you completely abandon notions of humanity to sate your hunger. Whenever you enter a rage, you can allow your blood to leave your body, leaving yourself as a blood totem. The blood totem is immune to all damage, immobile, and immune to all conditions. You decide whether any equipment you are holding or wearing becomes integrated within the totem. While your blood is separated from your body, it is vulnerable to being damaged. If it is reduced to zero HP, it returns to the totem and you must make death saving throws as normal.

Your blood has the following properties:

-It cannot move further than 30 feet from the totem.
-Whenever it takes the attack action, it can make three attacks.
-Whenever it attacks a creature, it can land a critical hit on a 19-20 when targeting a creature with less than half it's hitpoints.
