The Echo Shield is a defensive weapon used by Toa Sonitous. The Shield is semi-sentient, and when Sonitous wills it to, it can reflect the sound waves around it and focus them at a specific target at a determinable pitch and velocity. Effectively, it reflects any sounds in the surrounding environment and channels them onto a specific target.

Unlike most Toa tools, the shield does not seem capable of channeling Sonitous' elemental power of Sonics.
