Argent’s Time Warp

You warp time around a target creature you can see within range, altering when they are able to act. 

A targeted creature you can see within range makes an intelligence saving throw against your spell save dc. On a failed save, the creature must reroll it’s initiative. This roll can not benefit from advantage or disadvantage, and they must use the new roll. 
A willing creature may willingly fail the roll to be affected by this spell.
