Recently, I soloed my way through the adventure tulgey (19 pages, free/pay what you want at DriveThruRPG). It is for the RPG system Cairn, but I used Caltrop Core (can be used with any setting/adventure). I changed four lines of Dungeon Magazine Issue # 39 and made it my solo engine. I created a warrior, rogue, cleric, wizard, summoner, and an illusionist. So, the PCs started their adventure on the road. Soon they entered the town of Galumph. Here they entered five locations, talked to six NPCs, and picked up two quests. On the second day they were back on the road and encountered two bandits. The PCs killed one. The other one surrendered. They took his stuff and left him tied up not far from the road. Yes, this later bit them in the butt.

The PCs killed a boar on day three. On the fourth day, they arrived at Sloe Fell. Unfortunately they took damage in the cavern (large poisonous spiders) and Sherry the rogue was poisoned. The PCs killed the spiders and later the scant shade bulls. They moved away from this site, set up camp, and that night they were attacked by a minotaur. They killed it, but realized travelling on the road was just too dangerous in their condition. On the fifth day they followed the coast south and found a small fishing village. It was here that they were healed and got a good night’s sleep. On the sixth day they were on the road again. On the seventh day they found magic mushrooms. On the eighth day it was more bandits which were scared away by an illusion of a devil.

On the ninth day they were forced into combat with a large shade bull. They killed it. On the tenth day they arrived at Frabjous. They visited four locations and talked to seven NPCs. They discovered some evidence and followed it down to where the saltwater spring was located. The trail ended at a dead beast, but then they were attacked by bandits with revenge on their minds. Two bandits went down and Sherry was killed. A Valkyrie showed up and the battle stopped. The Valkyrie took Sherry to Valhalla. No one felt like fighting after that. Maybe you will have better luck with this adventure.

Give this a try!
