Unsteady Force

When a creature you can see other than you within range is hit by an attack that targets only that creature, you may use your reaction to erect a shield of opaque mist around the creature.

Until the start of their next turn, all attacks, including the attack that triggered the spell, have disadvantage against the creature. In addition, if a Melee Weapon Attack against the creature misses while this effect lasts, the next attack against the attacker is made with advantage.
