Your spells go farther than normal.
You can alter a spell with a range of touch, close, or medium to increase its range to a higher range category, using the following order: touch, close, medium, and long. Spells modified by this feat that require melee touch attacks instead require ranged touch attacks. Spells with a fixed range have their range doubled, for the cost of 1 MP. Spells with a range of personal do not benefit from this feat.
MP Increase: Special. A reach spell costs 1 additional MP more than the actual MP cost of the spell for each increase in range category. For example, a spell with a range of touch increased to long costs 3 additional MP.
