Create Temporary Timegate

 School: Chronomancy (Transmutation)
(Intended for use with the Chronomancer subclass)
Area of Effect: A surface area of 20 square feet

Upon casting this spell, the caster twists the momentum of time to create a temporary gate between reality and the demiplane of time. The gateway is totally flat (2-dimensional), but can be in any contiguous shape the caster desires, up to 20 square feet in area. Care must be exercised, since denizens of the timestreams are attracted to this portal and may be lying in wait on the demiplane of time, or possibly even attempt to come through into reality. Timegates are a liability as much as a convenience.

Once in the demiplane, the caster has a limited range of motion, only being able to shift up to 4 days outside of combat determined by the roll of a d20. Each interval of 5 will represent a day(1-5 = 1 day, 5-10 = 2 days, 15 = 3 days, 20 = 4) with the specific number dictating what time of day it will be, representative of whichever interval it lands on (1 sunrise, 2 morning, 3, noon, 4 afternoon/dusk, 5 midnight). Inside of combat, this spell shall be deemed unusable in battled, as it's a bit broken init.

The caster must make a Wisdom save once the spell has been cast. Failure means the gateway collapses.
