Magic Boomerang

The Magic Boomerang appears in  Ultima VII.

Description
During the Gargoyle War, the gargoyles realized that their normal boomerangs weren't powerful enough to do any real damage. Thus, they developed the magic boomerang, which is more precise and can even fly through walls.

History
Although, these weapons were not introduced to the battlefield, after the Avatar ended the war, by the time of the Fellowship, the weapon had been nearly forgotten, with even the gargoyles themselves having lost interest in it. Only a few magic boomerangs still exist.

Ultima VII

 * Terfin, One is still in possession of the gargoyles.

Trivia

 * Despite its rarity, the magic boomerang isn't especially powerful. It actually is weaker than the standard boomerang.
