Fightin’ Shade (3.5e Maneuver)

You don’t need arrows to blot out the sun, you simply say the right words...

You create a cloud of shadowy illumination out to a 30-foot radius around yourself. All creatures in the area, including you, gain concealment (20% miss chance). Even creatures that can normally see in such conditions (such as with darkvision or low-light vision) have the miss chance in an area shrouded in magical darkness.

Normal lights (torches, candles, lanterns, and so forth) are incapable of brightening the area, as are light spells of level 3 or lower. Higher level light spells are not affected by darkness.

Lastly, while everyone else within this area of darkness also gains concealment, you ignore the concealment they gain from the darkness you create. However, you must still roll for miss chance from any other effects that give them concealment.
