Wondrous Item

Uncommon

This shallow ceramic drinking bowl is enchanted to repurpose spilled blood into new life. The bowl holds up to 8 ounces of blood. Once filled, the blood begins to slowly swirl on its own. If left to sit for 1 hour without spilling, the blood in the bowl becomes a gruesome tonic that pulses with a faint, internal glow. Drinking the entire bowl of still blood causes one of two effects. Roll a d12. On a 12, you take 12 necrotic damage. If this damage reduces you to O hit points, you are stable. On a roll less than 12, you regain the number rolled + 4 hit points instead. The blood is thick and sweet, but leaves a bitter aftertaste.
The blood's magic fades if it's poured from the bowl without being drunk. Once the bowl has been used in this way, it can't be used again until  1d4 days have passed.
