Acid Barrier

Fling the powdered components in the air and encircle yourself in a semi-transparent green and yellow spherical barrier. The barrier has 30 hit points. This barrier instantly dissolves any non magical object that comes into contact with it, this effect remains for as long as the barrier has hit points or until concentration is broken. If an object is capable of dealing damage to the creature and it is instead consumed by the barrier, subtract the damage from the barrier's hit points. A creature that touches the barrier must make a Dexterity saving throw or take 10 acid damage, this damage is subtracted from the barrier hit points.

The spell ends once the barrier has 0 hit points forcing each creature within 5 feet of you to make a Dexterity saving throw or take 3d6 acid damage.
