If you play tabletop RPGs, especially as a GM/DM, you comprehend the power that lies in cartography. To help your mapmaking skills, you can get 12 map tools with the Maps Extravaganza Revisited (affiliate link) bundle at Humble Bundle for cheap.

Your purchase gets you a lifetime license for Campaign Cartographer 3+, City Designer 3, Dungeon Designer 3, and much more! Being able to use high quality maps can really help a party navigate the world, better understand the battlefield, find the shops they want, and more.

This seems like a crazy deal! In addition, each purchase of the bundle will support Save the Children which “work[s] every day to give children a healthy start in life, the opportunity to learn in school and protection from harm.”
