Discovering Cairn RPG: A Fast and Fun TTRPG System
What is Cairn RPG?
Cairn reinvents tabletop roleplaying by stripping away complexity while preserving rich storytelling potential. This OSR-inspired system shines in spontaneous game nights where elaborate prep isn't practical.

Unlike rules-heavy cousins like D&D, Cairn replaces rigid classes with equipment-based character development. The elegant d20 roll-under mechanic (succeed by rolling under your ability score) creates immediate engagement. Wardens (GMs) facilitate through conversational rulings rather than rulebook arbitration, making every session fluid and dynamic.
The game assumes brave adventurers navigating a shadowy Wood filled with wonder and peril. Best of all? It's completely free on drivethrurpg.com!
Character Creation: Quick and Easy
Cairn demolishes the character creation bottleneck plaguing other systems.

Building your adventurer involves four simple steps:
- Define identity: Choose a name and roll for background flavor
- Establish capabilities: Roll 3d6 for Strength, Dexterity, Willpower (swap two if desired)
- Determine resilience: Roll 1d6 for Hit Protection
- Gear up: Select equipment based on background
This elegant process leaves maximum room for imaginative roleplay while eliminating analysis paralysis.
Gameplay Mechanics: Simple Yet Engaging
Cairn's brilliance lies in its distilled mechanical core.

The system revolves around:
- Intuitive d20 tests (roll under relevant ability)
- Streamlined combat dealing direct damage
- Protective armor mitigating harm
- Hit Protection representing dodging capability
This creates thrilling, fast-paced sessions where strategy triumphs over stat optimization.
