The Web spell creates a mass of sticky strands that resemble spider webs.
A Web spell creates a many-layered mass of strong, sticky strands similar to spider webs but far larger and tougher. The Web spell covers a maximum area of about 30 ft. in radius (roughly the same size as a Fireball). Creatures caught within the webs, or simply touching them, become stuck among the gluey fibers. Anyone in the area when the spell is cast must roll a Saving Throw vs. Spell with a -2 penalty. If the Saving Throw is successful, then the creature is free to move out of the area. A failed Saving Throw means the creature is stuck in the webs unable to move. Each round that a creature remains in the web, it must make a Saving Throw or be unable to move.
