Over the course of 24 hours, you can cast this spell to create a time loop in a selected area no larger than 5 miles. Over the course of these 24 hours you forge a diadem of pure temporal energy, using a casing crafted from pure sapphire worth no less than 3000gp. The diadem is diamond shaped, and about as large as a fist. The time loop ranges from 12am on the day the diadem is hidden within the 5 mile area, going up until 11:59pm the following night. Each day when creatures within the area awake, they perform the same duties they did the day prior, feeling a strange sense of déjà vu. If a creature chooses to make a check to attempt to identify the effects, they must instead succeed on a Wisdom saving throw. A success on this save allows the creature to properly identify they are in a time loop and that they must break free to continue unto the next day. A creature who fails cannot realize this (even if informed by another creature who did succeed), though they can remake the save each following loop until they do. To end this spell, a creature must destroy the diadem, which has an AC of 18 and 50 hit points. The diadem is immune to divination magic used to determine it's location. Creatures which leave the time loop before the diadem is destroyed are returned to their same position in the time loop the following day.
