As part of a secret server’s Secret Santa event of sorts, Jojiro inspired me to create a “one-roll biome” and suggested a D6 one-roll discovery table method. I wasn’t familiar with the one-roll discovery table, but after putting one together I’ve fallen in love with it.
How does it work? Well, it’s pretty simple. The one-roll biome is actually just a miniature adventure setting laid out on one progressive table instead of on a map, a map key, and an encounter table. Each time the party explores further into the region, the Referee rolls a D6 to find out what the party discovers, checking off entries as the party advances. Each discovered entry acts as a location, a creature encounter, or a specific event—sometimes all three in one.
Care to see it in action? Check out The Rain-Cursed Valley of Tekhannaya, which just so happens to share the location of an upcoming adventure I’m developing for Sojourn and 5e. You can play this one-roll version right now using Sojourn or any other fantastical roleplaying system of your choice.
Let me know what you think—especially if you wind up visiting Tekhannaya at your own table!
