Ray of Alchemical Negation

Casting Time: 1 action
Range: 60 feet
Components: V, S
Duration: Instantaneous

You launch a ray of blazing, polychromatic energy from your fingertips. Make a ranged spell attack against an alchemical item or a trap that uses alchemy to achieve its ends, such as a trap that sprays acid, releases poisonous gas, or triggers an explosion of alchemist’s fire. A hit destroys the alchemical reagents, rendering them harmless. The attack is made against the most suitable object Armor Class.

This spell can also be used against a creature within range that is wholly or partially composed of acidic, poisonous, or alchemical components, such as an alchemical golem or an ochre jelly. In that case, a hit deals 6d6 force damage, and the target must make a successful Constitution saving throw or it deals only half as much damage with its acidic, poisonous, or alchemical attacks for 1 minute. A creature whose damage is halved can repeat the saving throw at the end of each of its turns, ending the effect on a success.
