From inside front cover: This book was designed to be used by players. They should know where (and how) to obtain the ingredients listed here. Do not, however, just give away the ingredients--they are very rare. Many good adventures can be created around the search for special ingredients. Traps, dungeon entrances, old buildings, etc. can be provided for searchers to stumble into. Be very strict with the ingredients and mixing procedures. Exact stiff penalties for mistakes in concoction. Characters will DIE if they aren't careful. Feel free to modify the potions described here or create your own similar ones. Experiment and enjoy.
