Because of the overcomplicated and tedious crafting rules that has plagues D&D from the age of time, books on the subject of making your own things in Dungeons and Dragons have been scarce.
More Damage Through Alchemy, by Tangent Games, is one of the few crafting books that adds a considerable amount of meat to the crafting ability. Built for 3.5, though fully compatible with Pathfinder, it provides a list of items and new rules for Craft Alchemy. If all you find yourself doing with Craft Alchemy is making acid, the book provides various types of acids, bases and new alchemical products that can hinder enemies, blind foes and help comrades. The 24 page book is quite balanced except a few spots where the product seems to do a bit much, despite the logical reasons behind it. Layout is great, and there’s a neat table in the back of the book for quick reference to what each of the new concoctions do.
