Turn Back Time
(Alteration)(Time)

Range:  0
Duration:  Permanent
Casting Time:  1
Area of Effect:  Current plane of existence
Saving Throw:  None

This spell turns back the clock of time for the entire current plane of the caster, by an amount of at most one year per level of the caster. The years are relived for the years set back. Only extraplanar creatures and the caster are aware that the clock was moved back. There is no known way to undo this spell.
A mortal caster is never granted such a spell. A demigod caster ceases to exist, permanently. Full deities must roll 1d20; on a 19 or 20, the deity ceases to exist. Else, the deity permanently loses 20 points of Constitution.
