Sudden Still

(Miniatures Handbook, page 28, DnD 3.5)

[Metamagic]

Once per day you can cast a spell without gestures without special preparation.

Benefit

Once per day, you may apply the Still 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 Still Spell feat normally, if you have it.
