>>One other katana question - why does it require both two hand and one handed weapons to wield one handed? Is there any inherent bonus or benefit to a katana training that other weapons don't have?<<
I suspect that this dates back to when katanas were released, and they were considered something "special"; the Artkati alone know why. I mean, they do feeble damage compared to a claidh. But you had to go on a special quest back then just to get a 0x katana. Nowadays they are a dime a dozen. In the last 6 months I have found at least four magical metal katanas on critters, ranging from ora to vaalorn. I can't even sell them. Considering that you can use a spear or a trident one or two handed just by training in polearms and using the "grip" command, it doesn't make all that much sense logically either.

"Oh, that's the projection of a hypothetical offspring from a union between Sauron and Cruella de Ville; we use that as a baseline for determining character alignment."
