Darkvision (Extraordinary ability)
Darkvision is the extraordinary ability to see with no light source at all, out to a range specified for the creature.
Darkvision is black-and-white only (colors cannot be discerned). It does not allow characters to see anything that they could not see otherwise – invisible objects are still invisible, and illusions are still visible as what they seem to be. Likewise, darkvision subjects a creature to gaze attacks normally. The presence of light does not spoil darkvision.
