"Time can kill faster than you'd think, especially so if you help it along..."

You attempt to rapidly age one humanoid creature that you can see within range. The creature must make a Constitution saving throw and on a failed save, it begins rapidly aging. Creatures that cannot age, such as constructs, and creatures that make a successful save aren't affected. The aging is proportional to the natural lifespan, and all creatures are affected equally. Creatures show signs of aging according to their race, such as wrinkles or silver hair, and have decreased physical abilities.

At the start of every turn, a creature affected by this spell loses one point of Strength, Dexterity, and Constitution. The creature must make another Constitution saving throw at the end of each of its turns. If it successfully saves against this spell three times, the spell ends. The successes don't need to be consecutive. Should an ability score reach 0, the creature dies of old age.

The aging and reduction in ability scores caused by this spell are magical, not natural, and can be reversed by a Greater Restoration spell.
