Widen Spell

You can increase the area of your spells.

You can alter a burst, emanation, line, cone, or spread shaped spell to increase its area. Any numeric measurements of the spell’s area increase 100% (doubled). For example, a Fireball spell (which normally produces a 20 foot radius spread) that is widened now fills a 40 foot radius spread. Spells that do not fill an area of any kind are not affected.

An widened spell adjusts a spell by three levels.
