You begin to tamper and adjust the timeline of the even which has hapenned few seconds ago, with a possible outcome changing scenario being forced into the new timeline.
You can cast this spell at the end of another creatures turn, only after any other effects apply and happen at the end of their turn. Choose one attack, ability check or saving throw roll that was done by chosen creature during their turn.
The events of that turn are rewritten and creature now has to roll again with the same modifiers and your choice of advantage or disadvantage. While all the new effects take place in the new timeline, you and the creature of your choice take 3d8 psychic damage for the stress caused by ripples from this spell in the timeline.
* - at the end of a creatures turn
