Are there any rules for web removal. How does fire affect webs?
"The strands of a Web spell are flammable. A flaming weapon can slash them away as easily as a hand brushes away cobwebs. Any fire can set the webs alight and burn away one 5-foot square in 1 round. All creatures within flaming webs take 2d4 points of fire damage from the flames."
Web (Ex): "An entangled creature can escape with a successful Escape Artist check or burst the web with a Strength check. Both are standard actions with a DC equal to 10 + 1/2 creature's HD + creature's Con modifier. Attempts to burst a web by those caught in it suffer a –4 penalty."
Web (Ex) Sheet: "Each 5-foot-square section of web has a number of hit points equal to the Hit Dice of the creature that created it and DR 5/—."
