Spider fang (weapon)

A spider fang is a magic +1 dagger, black or dark purple in colour. It has the ability to cut through webs without getting stuck, and once per day it can either weave a web, or a curtain made of cobwebs, suitable for hiding or concealment. If a curtain is created and a creature touches it, it collapses and causes the creature acid damage. The dagger is worth around 11,000 gold pieces.
