Source: Unearthed Arcana
Your eyes are particularly well suited to using darkvision, but they are less well adapted to what others consider normal light.
Benefit: Add 10 feet to the range of your darkvision. Drawback: You take a -1 penalty on Spot checks when in areas of bright light.
Special: You must have darkvision as a racial ability to have this trait.
