Need an opinion: If I use Bright Worms (PHB2 p105) in the same area as a Web, will the Web remain or will it burn away?
The argument for burning: Bright Worms is Conjuration (creation) Fire, and inflicts fire damage on the creatures that it targets.
The argument for remaining: Bright Worms creates "a knot of living light with wormlike tendrils" that do not attack allies, and just sort of drift around, until enemies enter the area, at which point they lash out and combust the creatures that they touch.
The question is, at what point is there actual fire? Only at the point of contact, all along the worm during contact, or all along the worm at all times? I know it'll be a DM call, I'm just trying to decide if my "web will remain" argument is strong enough to present.
