Chronal Reset

You bend time around yourself and reach backward to fix a mistake you once made. When cast using a 9th level spell slot this spell requires no material components, as you undo a single recent event by forcing a reroll of any roll made within the last 10 minutes. Reality reshapes itself to accommodate the new result. For example, you could undo an opponent's successful save, a foe's critical hit, or a friend's failed save. You can force the reroll to be made with advantage or disadvantage, and you can choose whether to use the reroll or the original roll.

When this spell is cast as a ritual it requires the following material components, a piece of ice taken from the river Styx, a fragment of a dream, the blood of an immortal 100,000 GP in various mundane components all of which are consumed upon casting. When cast in this way you pull at the strings of time and fate to change 3 events that has occurred during the caster's lifetime. When the ritual is completed the DM decides the repercussions of the changed event. Creatures native to the material place fade away as time resets itself, A creature native to the material place may save themselves from fading away by casting the wish spell to preserve themselves though in the process they are shunted and bound to the outer planes.
