Gwani Horn

The Gwani Horn has the same effects as the Horn of Praecor Loth, albeit through to it being much smaller, its powers are also more limited, as it can only smash blocks of ice instead of shattering buildings.

The Gwanis of the Serpent Isle had this Horn for generations, until Vasculio stole it, knowing of its powers. He put the horn into a force field in his base in Skullcrusher, so that his pize wouldn't be stolen by anyone. The Avatar got the Horn in Ultima VII/2, after finally getting the Dispel Field-spell, and used it to free Gwenno's body from an ice block in the Gwani's cemetary, so that she could be resurrected.
