Night Vision (True Night Sight):
You see normally in natural darkness as if it were daylight. This works outdoors at night and in unlit areas underground. However, magical darkness still blocks your sight completely. Normal obstacles like fog, smoke, and solid barriers affect you as usual. If range for Night Vision is unknown, and is needed, DN uses 60 feet as a default.
Twilight Sight:
Outdoors at night, you see in twilight, dusk, dawn, or under a clear full moon as though it were daytime. This ability doesn't function indoors, underground, or in total darkness. It requires some ambient lighting from twilight, dusk, dawn or full moon to work.
Dark Sense:
In complete darkness, you have a 40% chance to sense that something is near within a 30-foot radius. You can attempt this once per hour, or whenever the DN calls for a check. Success gives you vague awareness, presence and rough direction only, not precise location, number, or identity. This sense doesn't count as sight and doesn't automatically grant combat advantages unless the DN rules otherwise. It won't pierce walls or barriers.
Thermal Vision:
You perceive heat contrasts, warm bodies, hot metal, cooling surfaces, even in total darkness. You can identify living creatures and recent tracks by temperature differences, but fine details, colors, text, and subtle features remain indistinct. Thick stone, metal, glass, heavy insulation, or uniform temperatures can block or confuse thermal vision. Magical darkness doesn't stop heat detection, but solid walls and barriers do. If range for Thermal Vision is unknown, and is needed, DN uses 60 feet as a default.
Vision Adjudication Notes:
Magical darkness defeats even Night Vision and Twilight Sight, though Thermal Vision may still detect heat signatures and Dark Sense can ping presence within its rules. When multiple vision modes apply, use whichever gives the clearest result. Don't stack bonuses. Visual illusions fool Night Vision and Twilight Sight. Thermal Vision may see through heatless images. Dark Sense ignores purely visual tricks.
