Humble Bundle and Paizo have announced the one-week extension of the So You Wanna Try Pathfinder Book Bundle. The Book Bundle is Humble’s most successful to date, selling over 100,000 bundles of Pathfinder Roleplaying game PDFs. It has raised over $180,000 for Code for America, a national nonprofit, which helps municipalities and government institutions implement programs based on open-source software solutions.

Paizo and Humble created a special digital deal to help players access Pathfinder and support a great open-source cause. Inside this bundle, you’ll find a complete set of digital assets to get you started playing Pathfinder—and inspire you to keep playing for many adventures to come. This includes over $400 in rulebooks, world guides, adventures, and accessories—with top-notch high-fantasy lore and art.

All save one of the products in this bundle are PDFs that you can redeem with codes at the Paizo Store, one code per tier. There are three tiers to this bundle, starting at $5 and ending with a digital $25 tier. The last tier also includes the Pathfinder Adventure Path: Abomination Vaults for Foundry VTT.

Humble Bundles offer great deals and support great causes. Purchasers get a say in how much of their donation goes to each participant at checkout.

The So You Wanna Try Pathfinder Humble Bundle will end on March 2 at 11 am PST.
