School: Chronomancy (Transmutation)
(Intended for use with the Chronomancer subclass)
Duration: Determined by caster: up to 10 minutes / level, or up to 20 minutes / level if reversed

Age Person:
This spell speeds the aging process of any creature of Intelligence 2 or greater. The creature ages up to one year per level of the caster. The exact amount must be set to the nearest month before the spell is cast. Aging occurs at a rate of one month of aging every 50 seconds of time passed (1 year per 10 minutes). No Death Save is required. While undergoing the change, any action attempted is performed at one-half normal ability.

The material component is a small piece of polished amber and an ounce of ichor from a Aeon Behir. The affected creature must be touched, and it receives a Wisdom save if unwilling.

Rewind Person:
The reverse of this spell, Rewind Person, cannot bring back the dead, but it can reduce the age of the recipient by up to one year per level of the caster. Age reduction occurs at a rate of 1 year of de-aging every 20 minutes of time passed, and a Death Save must be either passed once or failed twice. If the Death save is failed twice, the target dies from shock, even as its body continues to grow younger. The creature must still be touched, and it receives a Wisdom save if unwilling, to avoid the effect.

Material components are the same as above, plus a cup of pure spring water subjected to the demiplane of time for one subjective day.

Inspired by the 2e AD&D spell Accelerate Lifeline, from the Chronomancer suppliment (TSR 9506).
