Sands of Time

The Sandglass of Regression is an optional item in Dragon Quest IV. Appearing as an hourglass filled with sand, it can be found in the Cascade Cave by using the Stone of Drought, which can be found by checking the one square of the beach in Seaside Village that is dry when the tides rise at night. When used in battle, they reset the battle to what it was one turn earlier, giving the player opportunities to rectify mistakes and bad turns of luck.
