Enlarge Spell

Enlarge Spell [Metamagic]]]

You can cast spells farther than normal.

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 50ft. +5ft./level, while medium-range spells have a range or 200ft. +20ft./level and long-range spells have a range 800ft +80ft./level. An enlarged spell uses up a spell slot one level higher than the spell's actual level.
Spells whose rangers are not defined by distance, as well as spells whose ranges are not close, medium, or long, do not have increased ranges.
