You can increase the range of your spells.
BENEFIT
You can alter a spell with a range of close, medium, or long to increase its range by 100%. An enlarged spell with a range of close now has a range of 50 ft. + 5 ft./level, while medium-range spells have a range of 200 ft. + 20 ft./level and long-range spells have a range of 800 ft. + 80 ft./level. Spells whose ranges are not defined by distance or spells whose ranges are not close, medium, or long, do not benefit from this feat.
MP Increase: +1 (an enlarged spell costs 1 additional MP more than the actual MP cost of the spell.)
