Sound Bubble - Bard

When this spell is cast, an invisible bubble springs into existence. This can be centered on and mobile with the caster or can be cast on an area. The mobile bubble has a radius of 10 feet, while the area bubble has a radius of 5 feet per caster level. The bubble has only one effect: sound can't pass through it. Thus, sound generated within the bubble can't be heard by those on the outside and vice versa.

Bards often use this spell to enhance the quality and effect of their performances. It is useful when a bard wishes to use one of his talents in a dungeon or other limited setting in which noise is sure to draw unwanted attention.

Besides its entertainment functions, sound bubble is also useful in many situations in which silence is used.

The material component of the spell is a blown egg shell or a soap bubble.
