Cityscape (2006)

An Essential Guide to Urban Adventuring

From the back cover:

As Deadly as Any Dungeon

There's more to adventuring than crawling around in dungeons. The city holds many avenues of peril and intrigue. It teems, with adventure and offers unsurpassed opportunities and challenges. Dark alleys, busy guild halls, rowdy taverns, fetid sewers, and platial manors hold secrets to be discovered and mysteries to be explored.

This supplement for the Dungeons & Dragons game reveals the city in all its grandeur and grimness. It makes the "urban dungeon" feel alive with politics and power, especially through influential guilds. This tome also describes new feats, spells, urban terrain, hazards, and monsters guaranteed to make the party's next visit to the city a vibrant and exhilarating event.
