A d20 fantasy roleplaying supplement centered on the warp spasm, a supernatural transformation associated with legendary heroes of Irish-inspired lore. It provides rules for creating a warped hero, using the riastradh, and gaining new feats, along with the warped one paragon class. The book also includes a fully stated non-player character and additional Bardic Lore for integrating the concept into a campaign.
