Blur (Archmagic)

Your body becomes blurred, shifting and wavering to all who can see you. For the duration, any creature has disadvantage on attack rolls against you. An attacker is immune to this effect if it doesn't rely on sight, as with Blindsight, or can see through illusions, as with Truesight.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, increase the spell’s range to 30 feet. For each slot level above 2nd, you may target an additional willing creature you can see within range. Whenever an affected creature other than you is hit by an attack, the spell ends for that creature
