Thessilin's Minor Time Ravage

You pull upon the strings of time, and force it into a bubble that launches itself towards one target of your choice.  Make a ranged attack roll against one target within range.  On a hit, the target takes 2d6 necrotic damage as time momentarily speeds up.  If applicable, one level of exhaustion is added to the target creature.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 4th
