Murksight (Su)

Effect The witch can see through natural fog, mist, and rain without penalty, ignoring any concealment bonuses gained from such effects. If the effect is created by magic, the witch can see up to 15 feet without penalty, with normal penalties and effects applying beyond that distance. This ability functions underwater as well, allowing the witch to see in murky water as though it were clear. This does not allow the witch to see anything she could not see otherwise, such as an invisible creature.
