Widen Power

You can alter a burst, emanation, or spread power to increase its area. Powers that do not have an area of one of these three sorts are not affected by this feat. Any numeric measurements of the power’s area increase by one-half. For example, a widened whitefire power (which normally produces a 20-foot-radius spread) now fills a 30-foot-radius spread. A widened power costs a number of power points equal to its standard cost +6.

You can increase the area of your powers.
