Description: You have mastered the art of casting spells at extreme ranges

Prerequisites: Enlarge Spell

You are able to increase the range of any spell that you can cast by 100' by expending an additional spell slot at the time the spell is cast. This feat may be used more than once per casting as long as the additional spell slot is expended for each use. Its effects are cumulative with those of Enlarge Spell, if used.
