Darkness Domain

As a melee touch attack, you can cause a creature's vision to be fraught with shadows and darkness. The creature touched treats all other creatures as if they had concealment, suffering a 20% miss chance on all attack rolls. This effect lasts for a number of rounds equal to 1/2 your cleric level (minimum 1). You can use this ability a number of times per day equal to 3 + your Wisdom modifier.

At 8th level, your vision is not impaired by lighting conditions, even in absolute darkness and magic darkness. You can use this ability for a number of rounds per day equal to 1/2 your cleric level. These rounds do not need to be consecutive.
