This spell creates an invisible, spherical barrier through which sound cannot pass. The barrier remains centred on the wizard, enabling an assault group to move in absolute silence without giving up inter-communication. However, sound cannot pass into the barrier either, making the party deaf for the duration. The material component is a glass globe.
