Distortion

Whenever an enemy attempts to read your aura or notice you while you are hiding, you may use your reaction to cast Distortion.

When you cast Distortion, you do not give off an aura and you are unable to be detected by any means. This only affects the enemy trying to read your aura or notice you. 

When Distortion is casted at higher levels, the effect persists for 1 minute and you can choose as many as people to be affected (along with the original enemy) as the spell's level minus one.
