#web spell

[what-witch-within-the-well]

May your heart ache with the pain you have caused

And your head heavy with doubt

with this, my strength and intent

I cast you out.

The web spell creates a mass of sticky strands that will cover and usually block an area 10' x 10' x 10', which conveniently conforms to most dungeon architecture.  (Jeff Dee from the Moldvay D&D Basic Rulebook, TSR, 1981.)
