Short Description

The study of celestial bodies, cosmic systems, and astrophysical principles. Used for navigation, scientific interpretation, and empowering space-related magic.

Success Criteria

Roll 1d100 + Astronomy vs. DR 100

Effects

Success: You interpret astronomical patterns or data to support navigation, spellcasting, or scientific conclusions

‍

Combat: +5 bonus to your next spell from the following categories: Void Manipulation, Quantum Flux, Gravity, Chronology and Dimensions. This increase by +5 per 15 success rate.

Modifiers and Restrictions

–15 DR — High-precision tools or known system

‍–10 DR — You’ve previously studied this region or map

‍+20 DR — Unstable gravitational field or rare anomaly

‍+25DR — Alien, ancient, or encrypted stellar data

‍+20 DR — Attempting real-time stellar read with no sensor support

Action Examples

You explore an ancient vault containing pre-collapse navigational glyphs. You declare Astronomy to reconstruct the star system they describe. The GM sets DR to 120 due to age and drift. On success, you reveal a hidden jump route or stellar relic site.

‍

As enemies close in aboard a derelict station caught in low orbit, you use Astronomy to calculate the precise gravity vector created by the moon’s pull. You declare Astronomy to empower your Reverse Gravity spell and roll 125 in total, which provides you with a +5 bonus to the spell. In a known system, the bonus would have been +10 due to the -15 DR bonus.

Long Description

Astronomy in Cosmic Odyssey is both technical and mystical. You use it to read starfields, chart wormhole tides, or interpret sky-based prophecy. But it also enhances spellcasting—especially in categories dealing with space, time, and probability.Stellar wisdom enables pinpoint spell alignment, spell duration tuning, or enhanced effects when celestial conditions are right. Whether you're a technomancer, or prophetic mystic, Astronomy turns the stars into allies.

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.
