Shattering Bell (3.5e Equipment)
From D&D Wiki
Shattering Bell: This iridescent glass bell gives a bearer the ability to shatter objects. Once per day, the bearer can say a command word and, once the command word has been spoken, ring the bell. In doing so, the bell replicates the effect of a shatter spell. The bearer decides whether to focus the effect on one object or objects in a radius, as per the spell, with a different command word. This ability can be used once/day.
