Tome of Beasts 2 is the third massive monster book. Not only is it an amazing resource of monsters, but the Open Game Content declaration is unusually broad as well. Whereas most monster books only put monster statistics under the OGL, Tome of Beasts puts "the monster names, descriptions, monster statistics, and monster abilities" under it. Aside from removing some Product Identity in the descriptions, and removing all unique monsters (which have proper names), a majority of the content is provided here.
