If the webs aren’t anchored between two solid masses (such as walls or trees) or layered across a floor, wall, or ceiling, the conjured web collapses on itself and the spell ends. Webs layered over a flat surface have a height or depth of 5 ft. rather than the full 20 ft.

Dexterity Save

• Failure: Target is restrained. Target rolls a Strength Save at end of their turns, ending effect on success.

• Success: No effect.

• Area Hazard: Once per turn, when a target moves at least 5 ft. into a webbed square, they roll a save. The web is difficult terrain and lightly obscures the area. The webs are flammable. If the webs or a creature inside the webs takes fire damage, the web will rapidly and harmlessly burn away after 1 round.

*Upcasting: The size of the cube increases by 5 ft. for each spell level above 2nd level.
