Temporal Push

Upon casting Temporal Push, the caster opens a partial slipgate to Temporal Prime and attempts to force creatures within a 10-foot radius sphere through it. This slipgate is not fully formed, so the subjects automatically slip back to reality at a later time. The creature must make a dexterity saving throw vs your spell DC, or it is thrown forward up to twice the spells level in rounds. 

The amount must be decided before the spell is cast. The spell removes the creature from reality for a limited time, allowing the caster to deal with other problems or prepare a welcome for the returning creature. The affected creature is not aware of any passage of time. Everything seems to shift about suddenly. If a physical presence is occupying the space to be returned to, the creature is displaced slightly on return.
