Time Travel

The caster manipulates the fabric of reality itself in order to alter the flow of time. The caster stops the flow of time for two minutes. Magical, indestructible, impassable, infinitely high, and infinitely long walls appear around the caster limiting their movement to forward and backward. During the two minutes, the caster can move forward and backward between the walls. For every step forward the caster moves one year into the future. For every step backward the caster moves one year into the past. The caster can end the spell before the two minutes pass. It is impossible for the caster to extend the length of the spell. No wish spell or any form of divine influence or intervention can extend the length of the spell. It is possible for the caster to cast additional spells during this time. If the caster were to expend a divine wish they could force themselves outside the flow of time. The caster would be permanently stuck outside of time, never able to rejoin the normal flow of time. Once the spell ends the caster emerges in the new time period in the spot where they originally cast the spell. If that space is occupied the caster is shunted to the nearest unoccupied space and takes 8d10 bludgeoning damage and 4d8 psychic damage. Once the spell ends the caster arrives in that new time period. The spell can't be recast for another 72 hours.
