Webstone

Webstone is the Realms name for spiderweb obsidian. Webstone is an obsidian variety in which small pieces of the stone have been cemented together by heat and pressure in an irregular mass, the joints showing as irregular, web-like lines. It is usually black, the join lines sometimes showing white, but brown, reddish brown, and rust-red varieties have been found. A typical specimen has a base value of 10gp.
