Enlarge Spell [Metamagic]
Benefit: An enlarged spell has its range doubled. Spells whose ranges are not defined by distance do not have their ranges increased. A spell whose area or effect is determined by its range has the dimensions of its area or effect increased proportionally. An enlarged spell uses up a spell slot one level higher than the spells actual level.
