Fire leaps and dances at your command, brightening or dimming.
Affect Normal Fire is a 3rd-level ritual.[PH2:212]
You gain mastery over nonmagical fire. For the ritual’s duration, or until you take an extended rest, you can manipulate nonmagical flames within 10 squares of you as a minor action. You can make a fire that normally provides dim light produce an equal amount of bright light, or you can double the radius of bright light a fire produces. Alternatively, you can diminish a fire’s light, reducing its area of bright light to an equal amount of dim light, or reducing its area of dim light to darkness. Reducing a fire’s light to produce no light does not extinguish the flame. You can extinguish 1 square of nonmagical fire as a minor action.
