If you’re looking for a way to test out your new, revised Dungeons & Dragons Player’s Handbook, you’ll want to check out this collection of fifth-edition D&D adventures from Humble. This $18 bundle features a collection of 38 adventures, campaigns, sourcebooks, and virtual tabletop modules created by the authors at Goodman Games, who have been writing supplementary content for Dungeons & Dragons since 2001.

The majority of these campaigns are drawn from the archives of Fifth Edition Fantasy, with some entries like Dark Tower retooled for D&D 5E, but two of these campaigns — Flight from the Forge Pits, and Tales from the Emerald Isle — are making their first appearance as part of the campy, creepy, and occasionally absurd collection of adventures included as part of this bundle.

If you’d like to sample some additional work from the independent authors featured in this bundle, this purchase also entitles you to a coupon to save you 20% on your next purchase from Goodman Games, which includes tabletop accessories and adventures for other systems outside of 5E.

Humble always sends a portion of each sale to benefit a nonprofit — in this case, your purchase will support the Global FoodBanking Network, a foundation that works to coordinate the efforts of food banks worldwide to help eliminate hunger. You can use the “Adjust Donation” drop-down menu to fine-tune how much goes to the publisher, the charity, or Humble.
