Blood of TycheLevel 15 Uncommon

This golden vial holds swirling liquid luckā€”and a deadly poison.

Consumable: Potion        1,000 gp

Power Consumable (Minor Action)

Drink this potion and spend a healing surge. You do not regain hit points as normal. Instead, once before the end of the encounter, when you make a skill check, ability check, or saving throw, you can reroll the check or roll but must use the second result.
