You create a 20-foot cube of sticky webs at a point you can see. Abiding Webs works identically to web, except as noted otherwise. These webs are crawling with tiny, harmless spiders. Damage to the web is repaired by the spiders that live in it, at the rate of one 5-foot cube per round. The repair occurs at initiative count 20. If the webs are completely destroyed, the spells end. The spiders themselves are immortal and need neither are or food to survive; the magic of the spell produces more spiders as needed.
