Your PC's are tracking the bad guys, but have lost them. The ranger searches for signs of the trail. The player rolls and gets a success. "What did I find?" Below is a small table to help answer that question. Have fun tracking the bad guys. ;) 1. Partially covered tracks. 2. Signs of a hastily-hidden fire-pit. 3. A partially chewed bone. 4. Brush marks across the trail. 5. A discarded piece of brush used as a broom. 6. A latrine trench or hole. 7. Discarded pieces of a lean-to or other temporary shelter. 8. Small pieces of rope or vine. 9. A dropped coin. 10. A broken arrow or crossbow bolt. 11. A broken button. 12. Rocks that have been used for sharpening. 13. A fragment of cloth caught in briers. 14. A thin strip of leather; a broken strap? 15. Signs of a false trail leading the wrong way. 16. A half-eaten piece of jerky. 17. Signs of a hastily broken down camp. 18. Signs of the party you are tracking having had an encounter. 19. Discarded dressings or bandages. 20. Physical signs of passage through the area: blood, skin, fur, hair, claw, etc.
