Blood Maw

Corrupted Blood.  If a creature takes poison damage from one of this creature's attacks, that creature must make a DC 16 Constitution saving throw or become poisoned. While poisoned by this feature, at the start of each of the afflicted creature's turns it takes 3d4 + their constitution score (Yes the afflicted's Con score, as their blood begins to fight against them) poison damage. If the afflicted's Hp drops to 0 (While they are poisoned) they die and become a "Blood Zombie" (See Blood Zombie for details). If the afflicted creature survives for 24 hours without curing the condition, they must then make a DC 18 wisdom saving throw or become mad unable to discern friend from foe, becoming a "Blood Driven" (See Blood Driven for details). This is now a greater curse as the afflicted's blood becomes fully corrupted. If the creature succeeds the save then they do not become a Blood Driven and they lose the effects of Corrupted Blood but their blood is still fully corrupted, this is now considered a greater curse. Creatures who have fully corrupted blood, their blood is now toxic and any creature who consumes the blood must make the saves against Corrupted Blood. A vampire however or any other undead who consumes it instantly becomes a "Blood Driven" no save. Creatures with fully corrupted blood also now has access to the Blood Hunter sub-class "Order of the Corrupted" (See Order of Corrupted for details)
