Custom Sword

The custom sword is a sword made with such care as to be perfectly balanced. For the warrior armed with this weapon, this makes it much easier to land a blow. It does not do any more damage than a normal sword would, but its superior balance makes it a fine choice over a blade of average construction.

Location
It is difficult to find these swords in the time of  Ultima VII, as they are not sold. The only sure location is inside the dungeon Deceit, behind a locked door.

Like a normal sword, the custom sword has an effectiveness rating of "6" according to Vetron's Guide to Weapons and Armour.

Trivia

 * Trainers often use these swords.
