Ray of Corruption

You unleash a sickly gray beam of toxic spores at your target. Make a spell attack against the target. If you hit a non-magical object that's made of organic material (such as a tree, wooden house, or massive skull), it melts away into a foul-smelling sludge. A single casting can destroy no more than a 10-foot cube of matter.

If you hit a creature, it takes 6d12 poison damage and 6d12 spirit damage with a basic Fortitude save. If you critically hit, the target gets a result one degree of success worse than the outcome of its Fortitude save.

Critical Success The target is unaffected.

Success The target takes half damage.

Failure The target takes full damage. Fungal tendrils swiftly digest the body and reduce it to sludge—the target takes 2d12 persistent acid damage.

Critical Failure As failure, but the target takes double damage, plus 4d12 persistent acid damage.
