Time Jump

The caster shifts their current self back in time up to 30 seconds into the past. Once the exact time has been selected you travel back to that exact point in time in the exact location you are currently standing. The world is exactly as it was during the time you selected and you are able to take 1 full action. After the action has been taken you jump back to present day and any actions you took in the past has now affected the present world. If any sort of a paradox was caused the caster causes an effect from the paradox table corresponding to the level of paradox caused. 

When casted at a higher level spell slot the caster gets the option of jumping an extra 30 seconds into the past for each higher spell slot level used.
