[[Summary::Thermalsight gives creatures the ability to sense heat sources.]] Creatures with thermalsight see a slight glow around heat sources. This exists even without a light source. Thermalsight is accurate enough to determine exact position within its listed area. This ability makes invisibility and concealment (even magical darkness) irrelevant to the creature (though it still can’t see ethereal creatures and must have line of effect to a creature or object to discern that creature or object). The creature usually does not need to make Spot check to notice creatures within range of its thermalsight ability.

[[Summary::Thermalsight gives creatures the ability to sense heat sources visually.]] Creatures with thermalsight see infrared radiation as a deeper rich red color, and in darkness infrared light often continues to radiate even when visual light has failed. Thermalsight is poor resolution, allowing shapes to be made out but not exact details, colors, or textures.
  
Unless noted otherwise, thermalsight is continuous, and the creature need do nothing to use it. Some forms of thermalsight, however, must be triggered as a free action. If so, this is noted in the creature’s description. If a creature must trigger its thermalsight ability, the creature gains the benefits of thermalsight only during its turn.

*Thermalsight shows heat not just life forms. Thus when in a hot environment or when all surrounding objects are hot, there is a -2 penalty to Spot checks.

Thermalsight[edit]

Thermalsight gives creatures the ability to sense heat sources visually. Creatures with thermalsight see infrared radiation as a deeper rich red color, and in darkness infrared light often continues to radiate even when visual light has failed. Thermalsight is poor resolution, allowing shapes to be made out but not exact details, colors, or textures.

For the most part it provides no benefit in normal lighting other than allowing the user to determine approximately how hot a creature or object in their line of sight is. In darkness, creatures continue to see objects in comparison to the background temperature. Objects hotter than the background temperature glow as if under faerie fire allowing their position to be pinpointed. Invisible creatures still give off body heat. Very hot objects can even "illuminate" the area as a torch. Many undead and constructs do not give off heat and are room temperature, and thus cannot be seen.

Going from room temperature to extreme heat suddenly provokes light sensitivity or light blindness as if it were a bright light.

Infrared light passes through objects gases, including fogs and clouds, but is stopped by 3 inches of stone, 1 inch of common metal, a thin sheet of lead, glass, or water, or 1 foot of wood or dirt. Magical darkness and blindness also prevent thermalsight as it is still visual based.
