...and the results were not pretty.
Aside from Scarlet Heroes for the OSR, one-on-one gaming is not very common option in published books. Even more so with Pathfinder, where the core dynamic of the game changes if you have just one PC.
To remedy that situation, Expeditious Retreat Press published a series of adventures. As of today there are about 16-18 for sale. Eleven of them are wrapped up in a large compendium book.
After the end to a very satisfying Solo Heroes game with Raineh Daze, I still wished to continue what we have, although my creativity was on a slow burn by this time. So I decided to try out some of these published adventures.
The adventures are all class and level-specific, with challenges and encounters had particular synergy with specific classes. You wouldn't run a Barbarian PC through a murder mystery.
Raineh wanted to be a sneaky drow exile, Gaussavin'ithra Barrighym, using the Nightblade class from Path of Shadows.
Of the Compendium adventures suitable for Bards/Rogues/etc,
Gambler's Quest jumped out the most at us. The opening scenario was intriguing; the evil nobleman Lord Kent is behind the recent raids on some towns, where orc and gnoll war parties absconded with their local heirlooms and tomes. And said nobleman is holding a gambling tournament at his keep, Castle Blackstone! Gauss is hired by the town to infiltrate the place as a prospective contestant, using the opportunity to steal back the heirlooms and possibly uncovering some other secrets of Kent's in the process.
Even though the adventure was sized for Rogues levels 2 to 4, the adventure set-up leaved much to be desired. The idea was that the PC would sneak around into restricted areas of the keep when she got some free time between tournament rounds. Disable Device and Stealth were of prime importance, but there were several encounters which just gave the middle finger to this. The gnoll and orc raiders are disguised as castle guards, and at least two of the heirlooms are in their barracks. As part of boxed text said the gnoll/orc lieutenant would automatically spot the intruding PC and enter combat.
Now, Raineh was lucky to have some nightblade tricks to entangle her foes, but the fact was that these monster leaders had a level in Fighter as well as heavy armor, making them really hard to fight even one-on-one. I genuinely don't see how a level 2 Rogue is meant to complete this adventure.
The majority of traps, from scything floor-blades to poisoned darts, are not keyed off of Reflex saves, instead using an attack roll with very high bonuses (+8 to +10). There are some potions of cure light wounds as stealable treasure, but given that rogues don't have healing spells ordinarily and the adventure's on a four-day time limit until the tournament ends, a wand of cure light and Use Magic Device are pretty much required for the PC to recover between encounters.
By the time Gauss fought and lost against the orc leader, she fell. If a PC falls in battle, they're instead captured and thrown in the dungeons, from which they can escape. The truth of the matter was that Lord Kent wanted to spy on the PC as a potential protege, as the stolen heirlooms he stole point to a hidden point of a legendary dragon-slayer and the staff she wielded. So when she was captured, Lord Kent offered to let her go if she worked for him. The gambling tournament was still going on, though. Raineh won.
Synopsis: This adventure has some good potential, and it's a shame that the underlying story of Lord Kent and the staff are beyond the scope of the book. The rival gamblers all had good personality traits, and the halfling assassin Sariah Redshift (one of Lord Kent's right-hand women) actually makes for an interesting rival for Gauss considering their talents.
But the adventure's weak points are in its set-up. Virtually every door in the "restricted areas" is locked and requires a Disable Device check, making parts of Gambler's Quest a boring dicefest. The mandatory monster encounters need to be changed to allow for surprise attacks, or nerfed into standard monsters of their kind.
From then on I didn't use any of the published adventures (the other thief ones are much higher level), and in last Saturday's session I made up my own story as Raineh grew to like Gauss and wanted to see where things went.
