Web

You conjure a mass of thick, sticky webbing at a point of your choice within range. The webs fill a 20-foot cube from that point. The webs are difficult terrain and lightly obscure the area. Each creature that starts its turn in the webs or enters them must succeed on a Dexterity saving throw or be restrained. A restrained creature can use its action to make a Strength check against your spell save DC to free itself. The webs are flammable; a 5-foot cube burns away in 1 round, dealing 2d4 fire damage to any creature that starts its turn in the fire.
