A D&D super-adventure that can be played as a mini-campaign or a series of small side adventures. Expedition to the Demonweb Pits is a D&D super-adventure for characters of levels 912. It is usable as a mini-campaign on its own, as a story arc in a Dungeon Masters regular campaign, or as a series of small side adventures with a big payoff. The structure is very flexible and eminently customizable. The adventure uses a new combat encounter format designed to make the DMs job easier and to speed up play. Heroes who become entangled in the adventures plot soon find themselves squaring off against the agents of Lolth and Grazzt across several planes, including the Abyss.
