Widen Spell (Metamagic)
This material is Open Game Content, and is licensed for public use under the terms of the Open Game License v1.0a.
Benefit: You can alter a burst, emanation, line, or spread shaped spell to increase its area. Any numeric measurements of the spell’s area increase by 100%. A widened spell uses up a spell slot three levels higher than the spell’s actual level.
Spells that do not have an area of one of these four sorts are not affect.
