What is this project?
The Ultimate Mega-Dungeon Accessory!
Bring unfinished dungeons to life OR make your own mega-dungeon from scratch!
By matching over 100 unique system-neutral encounters with tables of randomized room shapes, harrowing hazards, and tantalizing treasures you can create endless possibilities for dungeon locations.
This dungeon building tool is compatible with: 5e, Old School Essentials, Shadowdark RPG, and DCC RPG.
101 Dungeon Encounters Includes:
100+ (more with stretch goals) unique dungeon encounter descriptions
35+ lavishly hand-rendered hall and room maps to randomly pair with each encounter (also available as a poster for early backers or as an add-on)
up to 30 (with achievements) exotic and strange pieces of loot which can appear in any encounter
up to 30 (with achievements) oddities, NPCs, traps, creatures, and other hazards to be rolled when prompted in an encounter
Dozens of hand-drawn room puzzles, NPCs, and creatures for visual reference
Special Features
First 48-Hour Bonus Quick Reference Poster
Everyone who pledges in the first 48-hours gets a free Quick Reference Poster. This double-sided poster map features the room shapes for the random room generator. THe room generator is located in the book OR on the special reservation poster map (room generator).*
*NOTE on Reservation Map: The poster map (room generator) is available for everyone who reserved this special item early. It has added reference materials and is a perfect pairing with the Quick Reference Poster.
Plus, stretch goals can add to the three mega tables; Crazy Creatures, Randomized Rooms, and Lavish Loot. All the tools are within your grasp to quickly craft your own subterranean spaces!

Dunn the Dwarf
Follow Dunn the Dwarf! And earn rewards for Everyone!
101 Dungeon Encounters has attracted a lone adventurer, "Dunn". And you will get to decide his fate! Over the next few weeks you can vote (in 4 weekly polls) to decide what Dunn should do next. If Dunn survives all 4 rounds, we will reduce the requirements of all ACHIEVEMENT GOALS by 25%! That means a treasure room for Dunn, and real loot for you.
Will you vote to have Dunn jump in the pit? Throw his torch in the hole? Press on? Perhaps search the area for secrets? Or attempt to jump back over the pit and flee!?
You get to decide and reep the rewards. Personally, I am already a bit scared for the little guy. But hey, that's the adventurer's life!

The Lost Level
A Castle Whiterock Bonus Level
As part of the Castle Whiterock collective, backing this project at any pledge level gives you one more encounter in the LOST LEVEL. Backing all Castle Whiterock collaborators completes the LOST LEVEL with a total of 14 encounters PLUS the corresponding map and envelope packet from Goodman Games.
To complete your edition of the LOST LEVEL, check out the full collection of Castle Whiterock partners here. For each project you pledge, you get another encounter!
Delivery
For areas outside of the US we have seen prices vary. Canada is about double the prices of deliveries within the US, and most other regions vary from 4 to 6 times the costs. We ship with either USPS, UPS, or in some cases FEDEX, whichever offers the best rates. In addition, we are not certain at this time if added tariffs will affect these shipment costs.
All digital editions will be PDFs delivered through DRIVETHRURPG & BACKERKIT
Timeline
In case of delays in printing or shipping, we will alert you in an update ASAP. We have successfully funded 22 products on crowdfunding platforms (Kickstarter and Backerkit) and have a proven record of hitting our timeline, sometimes early!
If we reach ALL stretch goals we will be creating some new material. In this case, we can expect to see a slight delay.
