Potion of Cure Critical WoundsLevel 20 Uncommon
This potion covers your deep wounds in bright silver light, causing them to mend.
Consumable: Potion 5,000 gp
Utility Power (Healing) ✦ Consumable (Minor Action)
Effect: You drink the potion. If you have a healing surge, you must spend one. Instead of the hit points you would normally regain, you regain 3d8 + 20 hit points. If you are bloodied and don't have any healing surges, you still regain the hit points. If neither of these things is true, there is no effect.
