You are lucky indeed.My experience was strange--I found multiple Excalibers, Avengers, etc. but my Monk never got his coveted Z-bo. I'm convinced that the speed of my PC did something odd to the random number generator such that it *always* skipped over it. And I fought untold numbers of Demons/Pit Fiends looking for the #$%#$^ thing.
Anyway, if you are interested in importing this stuff to Wiz7, the above weapons will import at the rate of one per character. The Tora Maedate (along with Glass Slippers, Cape of Hi-Zen, and a few other rarities) doesn't exist at all in Wiz7, so unless you're hell-bent on importing a character with >18 vitality, don't worry too much about it.
