Decompose

 is a homebrew cantrip created by Matthew Mercer as a flavor spell for Caduceus Clay.

Description
The caster touches the corpse of a creature and causes significant decomposition and growth of fungus, moss, and perhaps a flower or two within a minute. Notably, it does not hinder resurrection, nor does it interfere with Speak with Dead. It also works on recently severed parts of living bodies. On a larger corpse (of an ettin) it caused vines to sprout and wrap around the body.

Notable Appearances

 * Caduceus decayed the body of a young blue dragon, Thelashas, who had been in the Folding Halls of Halas since before the Divergence.

Trivia

 * This spell doesn't count against the number of cantrips that Caduceus knows.
