You can increase the area affected by your spells.
Benefit
You can alter a burst, emanation, line, or spread shaped spell to increase its area. Any numeric measurements of the spell’s area increase by 100%.
Spells that do not have an area of one of these four sorts are not affected by this feat.
Level Increase: +3 (A widened spell uses up a spell slot three levels higher than the spell’s actual level.)
