Dungeons Deep

by John Joseph Adams (Designer), Celeste Conowitch (Designer), Robert Fairbanks (Designer)

Trapped. Stocked. Ready to Rock.

In a world of high fantasy adventure, every crumbling ziggurat, abandoned mine, or unassuming hole in the ground is a potential dungeon. Dungeons Deep delivers 16 drop-in dungeons designed to fit neatly into your D&D campaign—or to quickly expand an existing dungeon of your own design. Unleash your crack team of dungeoneers and enjoy the story!

Dungeons Deep is an essential addition to your GM Library:

* Challenge players with 16 prepared dungeons stocked with loot, traps, factions, and plenty of enemies
* Each dungeon offers tiered monster-loadouts for low, medium, and high level PCs—so you have 48 options available!
* Explore ruined temples, slime-filled caverns, a feywild oasis and more! Run them as-written or pick what works with your campaign and leave the rest!

These dungeons are ready. Your heroes might not be!
