At Home In The Deep

(Drow of the Underdark, page 47, DnD 3.5)

[General]

Your innate power over the darkness extends to your senses.

Prerequisite

Darkness as a spell-like ability, Darkvision

Benefit

You can see through the shadowy illumination created by a darkness spell as if the spell weren't there. This ability doesn't apply to other spells that have the darkness descriptor.
