It provides racial statistics for lesser and full derro, alternate racial traits, cultural details, quirks, names, and age and weight tables. The book also includes minor madness tables, five racial feats, three archetypes, a derro savant bloodline, new spells, poisoned nets, and strange magical items. The material supports derro-focused adventures in the Underdark or other campaigns with a broad scope.
