Terror From The Underdeep is a colossal boxed set for DnD 5E! This adventure path takes characters from level 8 to 16. It will keep your group adventuring for a year!

The huge box is packed with books, maps, handouts, pre-gens, and tokens. It includes:

 

We estimate that this boxed set will keep a party adventuring for up to 12 months of “real time.” We've been playtesting it for years so we know this is true!

This is the core plot that your heroes will encounter:

Raids from bloodthirsty humanoids and giants are common in the harsh Northlands. But lately, the attacks led by giantish foes are increasing in frequency and lethality. And it's not just one type of giant. Cloud giants invade the countryside from massive floating strongholds. Fire giants seethe from the broken lands to the east, lighting settlements ablaze and carrying off loot. Frost giants assault coastal communities from an immense iceberg in the frigid waters of the storm-wracked bay.

After the heroes conduct an assault on one of the giant's strongholds, they discover the giants are somehow affiliated with a mysterious cult that worships the “Beast Below.” The giants collect electrum during their raids, and are transporting it to the shadowy caverns of the UnderDeep, secreted underneath the Northlands. It matters not if the electrum is raw ore, minted coins, or crafted items. All of it goes down below, while the giants get to keep the more valuable gold, platinum and bejeweled items stolen from the Northlanders. But why? What purpose is served by sending vast quantities of inferior metal into the depths of the earth?

The heroes need to investigate other giantish fortresses to determine what nefarious role the cult plays in these raids and the route of the precious metal. Following the route of electrum through the UnderDeep leads to clashes with dark dwarves, degenerate fishfolk and other UnderDeep denizens. The route terminates at an abandoned sunken city on the shores of the Darksea inhabited by several factions in a desperate struggle to control the ruined city. There, the heroes finally meet The Beast Below...

What's in the box? We're still in editing so a few details might change, but right now we anticipate:

This project includes Advanced Advantage Playtest Packet #1, which is the first in a series of rules supplements for your fifth edition game. Think of this as "the Goodman Games house rules for 5E." Advanced Advantage doesn’t replace your fifth edition core rulebooks. It enhances them!

Playtest Packet #1 features a new way to utilize Advantage/Disadvantage in your fifth edition game. Introducing Dynamic Dice: instead of rolling two d20’s and taking the higher number, the Advanced Advantage system allows you to increase the size of the die for advantage. Do you have advantage on a d20 roll? Now you roll a d24!

What’s even better? This system can be applied to any die roll, and the results stack! Do you have double advantage on a d8 roll? Now you roll a d12! Disadvantage works in the opposite direction. Double disadvantage on a d12 roll now rolls a d8. And so on.

This is your chance to play with an innovative new rules system that compliments the game system you already know and enjoy. And you can play a role in defining the system for the final publication. Backers will be able to send in feedback based on play at their game table!

Goodman Games is famous for our adventures, which many fans consider to be some of the best fantasy RPG adventures of all time. Our most popular adventures have sold tens of thousands of copies. With that in mind, we have converted three of our famous adventures to the newest edition of 5E! Add on Idylls of the Rat King, Sailors on the Starless Sea, and The Lost Vault of Tsathzar Rho!

In addition, we are expanding our Compendium of Dungeon Crawl hardcovers. The first two entries in this line sold out almost instantly when first released. Each volume is a sturdy hardcover with 6-8 short adventures, each stand-alone, world-neutral, and designed for play in approximately 2-3 sessions. Each of these hardcovers is full of adventure for your 5E game!

Yes, we know! Created with the assistance of our friends at Strange Plastic, the miniatures are sculpted especially for this adventure. They will be cast to order for this project and not produced for retail. This is your chance to grab these unique showpieces!

Every 5E gamer knows how useful inspiration tokens can be. We will help you bring that to life!

The boxed set will include a sheet of six die-cut tokens printed on thick card stock. Each token features new full-color artwork depicting one of the iconic character classes. They are printed double-sided, so all twelve core classes are reflected. The tokens can be used by any character (regardless of the art depicted) to indicate if they currently have Heroic Inspiration.

In addition, as an add-on option, we are custom-manufacturing six tokens on poker-chip-like material and packaged in a polybag, ready for use at your table! These are printed double-sided so there is art for every core class.

Shipments will originate as follows, by region:

This project has a wide variety of components, so it's hard to estimate exact postage. In general, US orders that consist solely of books are eligible to ship via media mail. Other regions will ship via the most economical method.

There is additional information on common shipping questions in the FAQ.
