X-treme Dungeon Mastery (2nd Ed)

From the kickstarter: XDM: X-treme Dungeon Mastery, hailed as "the cure for the common game," is a tabletop role-playing supplement designed to improve every RPG you play. First published in 2009, it's high time for a second edition. We've brought back the original creative team for a fresh round of edits, expansions, illustrations, and much more.
