Mucus

2nd-level conjuration

Casting Time: 1 action
Range: 60 feet
Components: V, S, M (phlegm)
Duration: Concentration, up to 1 hour

You conjure a gob of thick, phlegmy mucus at a point of your choice within range. The mucus fills a 20-foot cube from that point for the duration. The mucus is difficult terrain and lightly obscures their area. If the mucus isn’t anchored between two solid masses (such as walls or trees) or layered across a floor, wall, or ceiling, the conjured mucus collapses on itself, and the spell ends at the start of your next turn. Mucus layered over a flat surface have a depth of 5 feet. Each creature that starts its turn in the mucus or that enters it during its turn must make a Dexterity saving throw. On a failed save, the creature is restrained as long as it remains in the mucus or until it breaks free. A creature restrained by the mucus can use its action to make a Strength check against your spell save DC. If it succeeds, it is no longer restrained.
