Time Bump

You see briefly into the future of creatures around you, and can slightly speed up or slow down their perception of time for a moment to influence how they behave in combat.

Up to two creatures of your choice that you can see within range must make Intelligence saving throws. Whenever a target that fails this saving throw makes an attack roll or a saving throw before the spell ends, the target must roll a d6 and subtract the number rolled, or add the number rolled to their attack roll or saving throw. A creature can willingly fail their saving throw(s) against this spell. 

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you can increase the duration of the spell according to the table below. 

(If you cast this spell using a spell slot of 6th level or above, the spell no longer requires concentration to maintain it's effect. However, the creature may repeat it's Intelligence saving throw 4 times, at even intervals for the duration. eg. if the spell last 24 hours, the creature may repeat it's saving throw every  6 hours. If the Creature passes any of it's subsequent saving throws, the spell's effect ends on that creature. A creature can willingly fail these saving throws.)
