Edratman and other folks,
I thought the comment was 'definitive' so I didn't try keeping all of my items 4 or less. I just did the #randomequip but it seems it's either strongly biased to gems or falls back to them if item doesn't work. With lots of trial commands I got one or two items in about 70 total possibilities. But I ended up with a few hundred gems.
Anyway I got full Dom3 in mail so on to patching!
