Silent Spell

Silent Spell (Metamagic)
You can cast your spells without making any sound.
Benefit: A silent spell can be cast with no verbal components. Spells without verbal components are not affected. A silent spell uses up a spell slot one level higher than the spell’s actual level.

(CL 5): You may prepare or use Silent Spell once per day without using a higher spell slot.
