The Harp of Building "This massive harp is carved from a metal never before seen on Scarn, resembling a greenish bronze more than anything else. The presence of the Harp confounds lodestones & causes compasses to spin. The strings are composed of silvery mithral, & each note played on them is accompanied by a flash of prismatic light."
Note: Requires Attunement by a Bard. Anyone else attempting Attunement is struck as if by Prismatic Spray(DC: 18). All structures created by the harp have a noticeably Elzan design, regardless of the wielder's wishes. Stone Walls created by the Harp are rose colored with glinting flakes of quartz notable within. The Harp weighs 800lbs.
Spells: The Harp may cast the following spells each once per day.
Stone Shape, Hold Stone, Move Earth, Fabricate, Wall of Stone, & Prismatic Wall
The Harp is also useful with respect to building. Once a week, a wielder may make a DC 18 Perform check, allowing its strings can be strummed so as to produce chords that magically construct buildings, mines, tunnels, ditches, etc. The effect produced in 30 minutes of playing is equal to the work of 100 humans laboring for 3 days. Each half hour after the first, a character playing must make a Perform check, with the difficulty increasing by +2. If it fails, she must stop and cannot play the Harp again for this purpose until a week has passed.
