I want to make sure my wizard dodges. Let’s make illusion better at level one!

Sudden Disappearance

Illusion cantrip

Casting Time: 1 reaction, which you take when you are targeted by an attack
Range: Self
Components: V, S
Duration: the one attack

You quickly flicker in and out of sink with reality to an enemy that is targeting you with an attack. The target must make a Wisdom saving throw. If the target fails, the attacker has disadvantage on the attack.

Thoughts?
