Distraction

You launch a fleeting illusion towards a creature you can see within range. The illusion resembles some sort of medium or smaller projectile coming towards them, such as a lick of flame, thrown weapon, or a few flying birds. The target must make a Wisdom saving throw. It can use a reaction. if it has one, to automatically succeed this save. Otherwise, the target is distracted by your illusion until the start of its next turn. If the target makes a saving throw before then, it has disadvantage on the save. This spell then ends.

A creature that can not see the illusion, as with blinded creature, or that can see through it, as with truesight, is immune to this effect.
