Sudden Widen

(Miniatures Handbook, page 28, DnD 3.5)

[Metamagic]

Once per day you can increase the area of a spell without special preparation.

Benefit

Once per day, you may apply the Widen Spell feat to any spell you cast, without increasing the level of the spell or specially preparing it ahead of time. You may still use the Widen Spell feat normally, if you have it.
