"Ever feel like you must abandon anything goblin related once your players reach level 5, or feel that the pool of goblin-based enemies is too minimal to draw from?
Look no further, for the Goblin Thesis (Volume 1) introduces 10+ new homebrew goblin enemies for your campaigns, ranging from CR 1 to 10 to allow these critters to command a strong presence in your games past first tier play! Inside lies the swamp-dwelling Bog Goblins, desert-scouring Sand Goblins, and the flame-born Ash Goblins.
Beyond just being a big old tome of flavorless stat blocks, this book includes small bits of lore for each monster as well as advice on tactical use when in combat, allowing you to truly challenge (and sometimes terrify) your players.
Go forth and enjoy subjecting your players to total goblination!"
