Success Criteria

d100 + Move Silently skill bonus versus DR 100 + modifiers + Target's General Perception

Effects

Success: You pass without being heard. If used in combat, opponents may lose the ability to react unless they detect you visually.

Modifiers and Restrictions

+25 to DR if walking on dry leaves, gravel, or similar crunchy surfaces

–25 to DR in loud ambient settings (machinery, wind, battle noise)

+10 to DR if targets are actively listening or on alert

-5 to DR per 10 meters distance to target

Action Examples

Crossing a hallway in complete silence while guard is alert:

DR = 100 + 10 (alert) = 110

Roll = 107 → SR = –3 → Failure

Long Description

Move Silently allows characters to minimize the sound of their steps, breath, and gear in order to approach unnoticed or retreat undetected. It is particularly effective in environments with distractions or ambient noise. While visual cover may aid, the skill’s focus is auditory.

The skill becomes more potent when sequenced with Hide in Shadows, Ambush, or Silent Takedown, and excels in situations involving guards, patrols, or sensor-equipped adversaries. Armor, carried gear, and surface material all play key roles in determining success.

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.
