Scarlet Heroes
CoreCore Mechanic
Checks: roll 2d8 + attribute modifier + highest relevant trait vs. difficulty number. Attacks: roll d20 + attack bonus vs. AC 20. Unique damage conversion: each damage die reads individually (1 = 0, 2–5 = 1 point, 6–9 = 2 points, 10+ = 4 points), making a single hero viable against hordes. Heroes roll a Fray die each round to auto-damage lesser enemies.
Best For
Solo players, duet groups (1 player + 1 GM), or anyone wanting to run classic old-school adventures without a full party — one hero can tackle any module.
Highlights
Solo and duet scaling makes any old-school module playable with one hero, Fray die and damage conversion solve the action economy, solo oracle and adventure generators included, compatible with B/X and OSR modules, Red Tide setting included
Considerations
Solo adventure tools require creative self-GMing, Red Tide setting is baked in (though easily reskinned), limited character options compared to full OSR games, older layout
