Adaptable NPCs provides a great slection of statblocks to add into any game world, taking the stress off of a DM to make a unique NPC from scratch or building off the small array provided by offical books like the DMG or VGtM. Well worth it, from the art to the small lore excepts adding flavor. The selection of standalone adventures in the end, introducing some of these NPCs to your characters is a wonderful added bonus.
Only gripe, as it has been expressed in other reviews, is the portayal of some of the female NPCs, with the often criticized scantily-clad armor or outfits of the fantasy genre.
