Poisoncraft: The Dark Art
This d20 fantasy sourcebook expands poisons into a complete system for brewing magical toxins, harvesting materials from defeated creatures, and creating antidotes. It includes more than 60 poisons, rules for designing new ones, poison decay and handling hazards, over 40 feats, more than 30 spells, new equipment and magic items, six prestige classes, creature templates, and baneful monsters. Adventure seeds for levels 1–20, fully detailed NPCs, poison-related domains, and guidance for using the rules in Monte Cook’s Arcana Unearthed campaigns round out the contents.
