Wondrous Item, Legendary

This cloudy blue potion was brewed from the blood of a living god. For each droplet that a creature drinks from this potion, the creature physically ages by one year. Brewing the potion is a long process that requires one droplet of divine blood to be added each year for many years. Such potions are always designated with the number of years that it took to brew them. For example, a Potion of Aging (25 years) contains 25 droplets.
