8th-level evocation (Sorcerer,Warlock,Wizard)
- Casting Time: 1 action
- Range: 90 feet
- Components: V, S, M (a vial of phase spider venom)
- Duration: Concentration, up to 1 minute
You create a 30-foot cube filled with shadowy, life- draining webs for the duration. The area is difficult terrain and heavily obscured. If the webs are not anchored to a solid object or layered across a floor, wall, or ceiling, the web collapses on itself and fades away, ending the spell. A creature that starts its turn in, or moves into the web during its turn must make Dexterity saving throw. If it fails it is restrained. A restrained creature can use its action to make Strength check against your spell save DC. On a success, it is no longer restrained. A creature that ends its turn restrained by the webs must make a Constitution saving throw, taking 6d8 necrotic damage on a failed save or half as much on a success.
