This beautifully illustrated supplement continues a series of releases that focus on how the environment can affect D&D gameplay in every capacity. Sandstorm contains rules on how to adapt to hazardous hot and arid weather conditions, such as navigating desert terrain and surviving in fierce heat or harsh weather. There are expanded rules for environmental hazards and manipulation of hot weather elements, as well as new spells, feats, magic items, and prestige classes. New monsters associated with deserts and wastelands are included, as well as variants on current monsters. Sandstorm provides enough adventure material included for months of gameplay.
