Harp Of Shattering

This finely crafted masterwork harp fits comfortably in one hand, but it requires two hands to play. The harp has 10 charges. By making a DC 10 Perform (string) check, the bearer can produce the following effects:

• break (1 charge)
• shatter (2 charges)

When the last charge is expended, the harp loses all of its magic but still functions as a masterwork harp.
