In-game description
"Katana +1 To enchant a katana is no simple process. Unlike conventional weapons, the katana is already a near-perfect fighting sword. To improve it usually requires a sacrifice, perhaps a dying samurai might beg a Wu Jen to infuse his fighting spirit into the spirit of the katana. The wielder of an enchanted katana, such as this one, must respect the customs of Kara-Tur and of the samurai who once carried this blade into battle. Not doing so could drastically change one's luck for the worse."
