So I have a pretty well decked out team, found all the other 2 specialty item for the other 5 classes (truth be told the 2nd druid item took forever), but i seem to have difficulty finding the second assassin item? I have the robe and during a going round at level 10 i usualIy find one or 2, but not the other item. start to suspect that I am dumb and already found it just didnt realize? Is it the combat gloves? Or one of the kick@ss swords?

I start to get frustrated and a bit bored and would love to find out if I am looking for a non-existing item or not. The last 3 times i beat this game my characters were around level 50 (but it was years ago so dont remember the items), this time i decided to get all the speciality items first.
But now everybody is already between lvl 100-200, 2000+ health points, we beat the grim reaper more times than i care to admit, we dove so much in lakes, my team just looks at a monster they perish, yet i fail to get the last item (or a second rod of catastrophe. What is the deal with that? Can you only have one of it per game? )
I d be grateful for any pointers or just a simple yes or no - should i keep looking for the assassin item?
Thanks!
