Wall of Sound - Bard

The wall of sound spell brings forth an immobile, shimmering curtain of violently disturbed air. The wall is made up of a number of 10 by 10-foot sections equal to the caster's level. These sections can be arranged as desired as long as the resulting wall all lies in one plane (that is, it must be flat) that stands up vertically.

One side of the wall, selected by the caster, produces a voluminous roar that completely disrupts all communication, command words, verbal spell components, and any other form of organized sound within 30 feet. In addition, those within 10 feet are deafened for 1d4 turns if they fail a saving throw vs. spell. On the other side of the wall, a loud roar can be heard, but communication is possible by shouting, and verbal components and command words function normally.

Anyone passing through the wall must make a successful saving throw vs. spell or suffer 1d6 points of damage and be permanently deafened. Deafened creatures suffer a -1 penalty to surprise rolls, a +1 penalty to their initiative rolls, and they are 20% likely to miscast spells with a verbal component.

A silence 15' radius spell cast by a higher-level caster specifically for this purpose will dispel the wall; the wall otherwise destroys all silence spells that come into contact with it.

The material component is a piece of slate and a finger nail clipping.
