You are briefly obscured by a harmless smoky puff and create a silent double of yourself composed of acidic fog adjacent to yourself in your space. You may move the double up to your remaining movement speed, and your full movement speed on your subsequent turns. The double is insubstantial and effectively weightless, but looks and behaves like you. It can mimic your actions and attacks, albeit harmlessly. A creature that does not succeed on a Wisdom (Perception) or Intelligence (Investigation) check cannot tell you apart from your double. The vitriolic double is dispersed if attacked or if it collides with a Tiny or larger object. A creature that makes a melee attack against the vitriolic double takes 3d6 acid damage, no save. You can choose to crash the double into a creature or object by moving it into that target's space. The double is dispersed and a target that fails its dexterity saving throw takes 3d6 acid damage, or half on success. When the vitriolic double is dispersed or the spell ends, every creature in a 5 foot-radius of the double takes 1d6 poison damage.
At Higher Levels When you cast this spell using a spell slot of 3rd level or higher, the acid damage increases by 1d6 for each slot level above 2nd. The poison damage increases when the spell slot used reaches 3rd level (2d6), 6th level (3d6), and 9th level (4d6).
