Caelius's Chance

For the duration of the spell, everything around you goes exactly the way you want. As a reaction to a creature within 60 ft of you making an ability check, saving throw, or an attack roll, you can choose the result of the roll, 1-20. You can do this after the creature rolls but before effects are determined. Each time you take this reaction you must make a spell casting ability check DC 10+the amount of times you successfully changed a result during this casting of the spell. Choosing a 20 or a 1 increases the DC by 2 instead of 1 every successful time. If you roll a natural 1 on the spellcasting ability check, there is a 33% chance you that you are unable to cast Caelius's Chance ever again. Once the duration of the spell elapses, you immediately suffer a streak of terrible luck. Any time you make an ability check, attack role, or saving throw in the first 24 hours after the spell ends you must make Wisdom Saving throw against the DC to change a creatures roll, when the spell ended. I.e. if during the spells duration you successfully changed 3 rolls to natural 20s then the DC would be 16. On a failure the result of the roll is a natural 1, which supersedes any advantage or other similar effects, on a success the DC is reduced by 1 to a minimum of 10 for the rest of the 24 hour period. This does not apply to the Wisdom saving throw made to resist its own effect.
