Flux Analyzer

The Flux Analyzer is a machine that can fix broken magical pathways in magical items, re-aligns them to work again as intended. Basically, it repairs broken magical items. This makes it quite useful and wanted, since only one is known to actually exist on the Serpent Isle.

The mage Gustacio of Moonshade owned the Flux Analyzer, until it was stolen from him by Vasculio, as he later told the Avatar in Ultima VII/2. The Avatar needed it to fix the Black Sword, so that it would be useful again and trap the Banes inside the Ether Gem. The Avatar finally found the machine in Skullcrusher, Vasculio's hideout, and used it to repair the Black Sword.

After that done, it lost its usefulness.
