The Bryce Blood Bowl

Bryce Canyon is one of the gems of the U.S. national parks system. Its strange geologic formations, breathtaking vistas, and twisting mazes make it an experience visitors don’t soon forget. Those same features, though, make one spot in the park an amazing template for a gladiatorial arena. The bowl between Liberty Castle and Wall Street […]

The Agate House

In the remote desert of Arizona, in Petrified Forest National Park, there sits an odd structure. It looks like a Native American pueblo. But instead of being made of adobe or stone, its walls are made from chunks of quartz the size of your head. This is the Agate House. It’s an archaeological marvel, and […]

Speleothems

Whether you want a social encounter, a combat encounter, or one that can shift between the two, this site’s combination of difficult terrain and exceptionally long sight lines promises to create a tense situation. Mongolia’s Gorkhi-Terelj […]

Ambush in a Barn

This encounter is meant to turn a relatively straightforward fantasy combat (a fight with a wizard and her goons) into something a little more challenging and dynamic through the use of mundane terrain. Lure the PCs into a barn, then trap them inside with opponents who are ready to make good use of the terrain. […]

Funneling Ambush

This is an encounter intended to funnel the party in a particular direction without leaving the players feeling railroaded. This version has the party chased down a mountainside into a cave, but you can adapt this to any terrain. The trick is to: Make the enemies tough. Make the terrain favor the enemies far more […]
