Featuring nearly $500 worth of products, the latest Book Bundle is sure to bring some holiday cheer from Humble Bundle. 37 different products made their way into this stocking stuffer, including Rappan Athuk and How Orcus Saved Christmas. These tabletop RPG ebooks are compatible with the dazzlingly popular Fifth Edition of Dungeons & Dragons. The best part of the deal is being able to help people in need: proceeds from the sale of these Book Bundles go to charities and developers you support.
This Bundle's default charity is the Navy-Marine Corps Relief Society. The NMCRS is a non-profit volunteer service organization that seeks to "provide, in partnership with the Navy and Marine Corps, financial, educational, and other assistance to members of the Naval Service of the United States, eligible family members, and survivors when in need; and to receive and manage funds to administer these programs." Like all Humble Bundles, purchasers can also select from a number of different charities and choose where all of their money goes.

As for the bundle's contents, there are three different tiers, each with different purchase rewards. These rewards are cumulative, so by purchasing the highest tier you will receive all of the products in the Bundle. The minimum $1 tier includes coupons, a couple of adventures, and some maps. The mid-tier, costing at least $9, includes 15 adventures, including City of Brass and everything needed for How Orcus Saved Christmas. The highest tier, requiring a minimum purchase of $18, includes all of the previous tiers as well as supplementary materials such as Rappan Athuk and a Creature Codex.
All of the ebooks are DRM-free and come in PDF format. This Book Bundle will run until Wednesday, December 18.
