In my homebrew campaign, a knight of a secret order named Bathin ordered the creation of two magical items for him.
Bathin's magic sword: a bastard sword that does 2d6(1d12), and can shoot out a web on the command phrase "bind their lies!", like the M-U/E spell web. It can "cast" the web out of the tip of the blade, or the pommel. The web can be shot out once per day.
Bathin's magic helm: when a person wears this helm, they feel a prickling sensation coming from the direction of any metal weapons in a 10' area, except those on the wearer of the helm, and anyone touching the helm
