Occasionally used by ogres and giants to deal with numerous diminutive foes, the Thunderwave Ring provides a medium of dealing with them simultaneously. A single aquamarine central stone encircled by ripples of silver, this simple yet effective ring is used for troublesome situations. When in danger, its wearer activates the ring by simultaneously touching the stone and saying "goodbye" in the Giant language casting Thunderwave from the magical ring. The rings traditionally carry 1-3 charges. 

Notes: Wearing the ring while touching the central stone and reciting "strength above all" in giant attunes this simple device.
