In May 2021, I soloed my way through The Chamber of Red Fang, a fun Index Card RPG fantasy adventure (free at DriveThruRPG). The RPG system I used was Tales of the Magical West. I am using the Solo Adventurer’s Toolbox as the solo engine. – So, the adventuring party is trying to escape from the country where they are now outlaws (they used unregistered magic and stole horses). They are intercepted by two bounty hunters. The bounty hunters are killed and looted. They continue their travels and the road turns into a trail (new country). This trail eventually comes to an ancient home of the dwarves. They explore it and discover a series of rooms down beneath the ruins. A Plague Willow comes to life, but Melissa heals it with a healing spell ( a cost of 11 points of mana with a critical success). They make some saving throws to get past the sigil, find a secret passage, and run into three darklings. Soon after defeating them, the characters run into the Big Bad. Dan becomes charmed and attacks Blade. Blade goes down (hit points at minus one) and the Big Bad is killed. Healing spells are cast and a cursed magic sword is found. It needs to be destroyed, but how? - -This free adventure is 11 pages long, has one map, 4 stat blocks, and four rooms. I used The Solo Adventurer's Toolbox (Bimler) to make the dungeon bigger.
