Farming for Variety

I’ve been farming Nemesis for blueprints, but hit a bit of a wall. But I noticed that I was getting a lot of the more common drops (blue and purples), while not getting some of the Items that I’ve never had drop (there are quite a few).

So yesterday I ran through a bunch of the boss monsters and played longer sessions to get more & different gear. And it worked. But it seems that not all boss loot is equal.

According to https://www.grimtools.com/monsterdb/ , there are 151 Boss Monsters and 10 Nemesis (17 - 7 alt phases). I did a pretty good job of following the campaign bosses up to Barrowholm.

Now, it could just be random luck, I was wondering, is there a good list of bosses that have the best drops? Any suggestions for getting the best variety of (preferably) purples?
