2nd-Level Conjuration
Casting Time: 1 action
Range: 60 feet
Components: VSM (a bite of spiderweb)
Duration: (C) 1 hour

You conjure a mass of sticky webbing at a point within range. The webs fill a 20-foot Cube there for the duration. The webs are Difficult Terrain, and the area within them is Lightly Obscured.

If the webs aren't anchored between two solid masses (such as walls or trees) or layered across a floor, wall, or ceiling, the web collapses on itself, and the spell ends at the start of your next turn. Webs layered over a flat surface have a depth of 5 feet.

The first time a creature enters the webs on a turn or starts its turn there, it must succeed on a Dexterity saving throw or have the Restrained condition while in the webs or until it breaks free.

A creature Restrained by the webs can take an action to make a Strength (Athletics) check against your spell save DC. If it succeeds, it is no longer Restrained.

The webs are flammable. Any 5-foot Cube of webs exposed to fire burns away in 1 round, dealing 2d4 Fire damage to any creature that starts its turn in the fire.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the area of the spell increases by 10 feet for each slot level above 2nd.
