Synchronicity

4th-Level Enchantment
Casting Time: 1 action
Range: Touch
Components: VS
Duration: (C) 1 hour

The creature you touch feels reality subtly shifted in its favor while this spell is in effect. The target isn't inconvenienced by mundane delays of any sort. The target always wins ties, can move through allies or enemies without spending additional movement, and attacks of opportunity provoked by the target's movement are made with disadvantage.

The target always finds a handy piece of cover available, and so has half cover while near walls or objects, and have suprior cover when they would otherwise have half cover. On the converse, the target always finds a way to their quarry. They ignore half cover, and treat superior cover as half cover. Additionally, the target has advantage on all ability checks made to drive a vehicle.

When the target of this spell rolls a 1 on an ability check, attack roll, or saving throw, they may use their reaction to treat the d20 roll as a 20. If they do, the spell ends for that creature.

In the event that two or more creatures under the effect of synchronicity are attempting to avoid being inconvenienced by each other, the creatures engage in a contest of Charisma each time the effects of the spells would oppose each other.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can target one additional creature for each slot level above 4th.
