You can increase the area of your powers.
Benefit: To use this feat, you must expend your psionic focus. You can alter a burst, emanation, line, or spread-shaped power to increase its area. (Psi-powers that do not have an area of one of these four sorts are not affected by this feat.) Any numeric measurements of the psi-power’s area increase by 100%. Using this feat increases the PP cost by 3 levels.
