One of the biggest challenges Torchbearer GMs face is creating dungeons or choosing published dungeons (especially if they weren’t specifically written with Torchbearer in mind).
I highly recommend crafting your own dungeons if you have the time. It’s fun! The Adventure Design chapter can help make it a snap, too! But you don’t need to shy away from published adventures, even from other games. They’ll make your life easier.
Whether you choose to make your own or use a prepackaged adventure, you’ll get the best results if you play to Torchbearer’s strengths.
