Fields of Blood: The Book of War

A d20 supplement for ruling realms, managing nations, raising armies, and resolving large-scale battles. Rules cover defining and converting realms, governing settlements and nations, taxation, recruiting and training troops, fortifications, and siegecraft. The system also includes guidelines for using existing magic in warfare, new battle and realm magic, prestige classes suited to mass combat, and appendices with spells and ready-to-use creature units. It is compatible with version 3.5 of the d20 system and can be used with an existing campaign or a new setting.
