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.
Level Increase: +1 (a silent spell uses up a spell slot one level higher than the spell’s actual level.)
Special: Bard spells cannot be enhanced by this feat.
