Roll 1d100. You can add the successrate to your fatigue threshold roll. First battle round is at DR 80, 2nd DR 100, 3rd DR 120, 4th DR 140 and so on.

After a battle, roll d100 aginst DR 100 and add +10 to DR for each Action Point lost during the battle. You regain 1 fatigue action point per 20 successrate.

Long Description

Endurance reflects a character’s resilience when pushed to their physical and mental limits. It plays a vital role during drawn-out battles, grueling marches, environmental challenges, or when resisting debilitating effects like fatigue or poison. The skill can reduce recovery time and extend your capacity to stay in the fight, especially when combined with Renewed Vigor (to recover AP), Winner Mentality (for high-pressure resolve), or Survival (for harsh environments).

Perfect for tanks, long-distance explorers, and support roles who must remain reliable under strain.

How to use this page

All the information above is intended as a guide to help you navigate the many situations that can arise during your game. Since it's both impossible—and frankly uninspiring—to plan for every possible outcome, players are encouraged to think creatively when using their skills. Game Masters, in turn, are encouraged to embrace and support that creativity.

Whenever possible, aim to resolve situations through narrative choices, logical thinking and role playing. If that’s not feasible, agree on a Difficulty Rating (DR) using the provided Success Criteria and Modifiers. These are not rigid rules, but suggestions - starting points to help you find the right level of challenge. The player describes their intended action, and the Game Master proposes a DR. This should be open to brief discussion at the table, ideally resulting in consensus. If not, the Game Master has the final say.

It’s important to emphasize that all suggested effects, modifiers, and action examples are exactly that: suggestions. If you’re unsure how to resolve something, they offer a reliable fallback—but wherever possible, we encourage you to push boundaries. That’s where some of the most memorable and exciting moments in play are born.

Sequencing and Potential Counters are far from exhaustive. With hundreds of skills, spells, and tech modules in the game, the possibilities are too vast to list. You’re encouraged to explore combinations that make sense in your story and setting and in the situations that arise in your game. Sequencing and countering are core to Cosmic Odyssey - they’re where strategic depth meets dramatic flair, and where legendary moments often take shape. Even if no sequencing and counters are mentioned, some certainly exists and can be smartly utilized.

So explore boldly, improvise wisely, and enjoy the game as it unfolds around your choices.
