Time Shift

With a shifting of your hands, so shifts the fabric of time. Strands are rewritten, forward or backwards in the relative continuity of time. As an action, the caster can target one creature or object within range, of medium size or smaller. Now, this spell's function differs depending on creature or object.

Objects. For every action that is spent concentrating on the object, the object can be forcibly moved through time up to 5 years per action spent. If moved through time backwards, the object undoes any damage or modification that has occurred in the time reversed. If an object were to be moved so far back in the timeline that it would cease to exist, the caster takes 1d6 psychic damage for every action spent concentrating on the object, due to the unnatural erasing of it's presence in the timeline, and it is erased. The same effect does not occur if an object is moved forward enough to decay, crumble, or disappear. That is just the natural process of time sped up. 

Creatures. For every action spent concentrating on a creature, the creature can be forcibly (Or willingly) moved through time up to 1 year per action spent. If this is forcible, the creature can make a Wisdom Saving throw against your spell save DC, resisting the time effect on a successful check. A creature reversed in time, loses any injuries, sicknesses, damage, and conditions done to them in the time that is reversed; as long as they are reversed to a time they didn't have any of these. They also de-age that amount of time. A creature moved forward in time, increases in age by the time moved forward. Like objects, if a creature is reduced in time so far back they cease to exist, then the caster takes 2d6 psychic damage for every action spent concentrating on the creature, as it is VERY unnatural to erase life that way. The same effect does not occur if a creature is moved forward enough to die of old age. 

Creatures can be raised from the dead with this spell. A corpse targeted by this spell must be concentrated on by this spell for 6 actions at the minimum, not succeeding if concentration is lost. The caster of the spell must make an additional spell save against their own spell save DC each round they're concentrating on the corpse. A failure ages them by 1d6 years. More than 3 failures results in the spell failing. If successful in casting on the corpse, the age of the corpse can be reduced by 2 times the amount of maximum time possible per actions. If the corpses age is reduced to a point where the creature is alive, the creature is fully resurrected. The caster then takes 4d6 Psychic Damage per actions spent concentrating.

At Higher Levels. For every level higher than 5th, the duration of the spell increases by a possible round. Time moved for objects increases by a maximum of 5 years. Time moved for creatures increases to a maximum of 2 years/action at 6th, 4 years/action at 7th, 5 years/action at 8th, and 10 years/action at 9th. Also any damage dealt by the spell is reduced by 1 die/2 extra level cast at. (Ex. At 9th level raising the dead only deals 2d6 psychic damage per action used, or at 7th level damage taken from moving an object far enough back to erase it doesn't deal damage anymore.)
