Drop the Myc (5e Spell)
From D&D Wiki
|Casting time:||1 action|
A thick layer of mycelium forms on the ground in a 30-foot square starting from a point within range. A low, dissonant humming sound emanates from it. For the duration, this fungus turns the ground in the area into difficult terrain. You can magically detect and pinpoint the origin of any vibrations within the area, such as a creature walking or an eldritch blast hitting the ground.
Additionally, the mycelium speeds up the decomposition of any corpses within the area, disguising the corpse under more fungus. Anyone trying to uncover a decomposed body can attempt an Intelligence (Investigation) check made against your spell save DC to reveal the corpse. This decomposition has no effect on the time limits of any reanimation or resurrection spells.
