Frostburn (2004)

From the Back Cover of the Book

Survival at Sub-Zero

Marrow-chilling conditions, deadly hazards, and other dangers threaten explorers of frostfell environments. A Wintry grave awaits those who venture forth unprepared, whether traveling through polar regions, frozen mountains, ice-glazed dungeons, or the Ice Wastes of the Abyss.

This supplement for the D&D game explores the impact of arctic conditions and extreme cold-weather environments on every aspect of game play. Along with rules for adapting to, navigating through, and surviving hazardous cold-weather conditions and terrain, Frostburn also includes new spells, feats, magic items, prestige classes, and monsters associated with icy realms.
