Stealth and Detection

Stealth and its detection thereof has been changed dramatically from vanilla Third Edition in The Domains of Dread. When a character enters stealth, they become hidden, unable to be seen by conventional means unless detected. The primary skill for detection is Perception, where the primary skill for stealth is likewise Stealth. Any character can detect another character even if they are not in Detect Mode, but Detect Mode confers additional benefits on part of the detector.

To perceive a hidden character, the detector passively rolls the following every turn (60 seconds IRT) if they are not in Detect Mode, and every half to quarter turn (30-15 seconds IRT) if they are depending on hard ranks in Perception:

d10 + Perception +/- environmental modifiers +/- miscellaneous modifiers

If their roll beats the DC set by the hidden character's total Stealth score, they are permanently revealed to the detector until line of sight is broken. A visual indicator will orbit the detected character to indicate to the detector that the character had been trying to hide.

Factors of Detection

Common factors which may make a hidden character easier or more difficult to spot in The Domains of Dread include:

1. Ambient light level and light level from held or nearby light sources;
2. Ongoing weather, including fog or storms;
3. Noise the hidden character is making from changing held items, equipment, or casting spells;
4. Whether the hidden character has the benefit of concealment;
5. If the hidden character has been recently detected by the detector;
6. Any spells which heighten or lower present perceptions.
