(Hemomancy)
You infect a portion of your blood and splash it on creatures within range. As you cast this spell, you must expend a number of hit points, allowing you to target 1 creature for every 5 hit points spent. Each creature must make a Constitution saving throw. On a failed save, the target takes 6d8 necrotic damage and is also infected for the duration. On a success, the target takes half damage and suffers no additional effect. An infected target is poisoned, can’t regain hit points, and whenever they take bludgeoning, piercing, or slashing damage, they take an additional 2d8 necrotic damage as they bleed profusely. A creature repeats the saving throw at the start of each of its turns, ending the effect on a success.
