What is Solidão

Solidão is a rework of the solo rules included in my previous game, Outline RPG. It's designed to fit in naturally with Forged in the Dark games, but it should work with any kind of system.

The procedure has three core components: the oracle, the event die, and the spark tables. The oracle is used whenever you need to answer simple yes or no questions; roll 1 to 4 d6's, and take either the highest or lowest value depending on the likelihood of the result. The event die is a different color, and is rolled together with the other dice; if its value matches the oracle result, you roll for a random event. Finally, whenever you need inspiration or can't figure out what happens next, you can roll for any combination of key words on the spark tables.

Solidão is in many ways, a shameless ripoff of all of these amazing projects. Be sure to give them a look:
