Sorry, I was drunk yesterday and it seems I misread your posts and snapped.
The random staff with many + skills is indeed very helpful in order to progress further. That will both increase the life of your minions and the damage output/gain of your totems.
This step is already meant as a "leap". You don't have to shrine craft a staff that way after all. The minions life isn't very important for fauzt. You can just recast them. And since you have to summon skeletal flayers all around you anyway in order to dodge Necrobots piercing attacks, lacking minion life isn't that much of a problem. So getting a rare or magic staff with many + skills is indeed one of the steps that helps you progress a lot until you finally can farm a Ghal rune.
As for baal: He's really tricky. I couldn't kill him at this point, not even with a complete respec. But that's not a problem either. The only charm you'll be missing out on is the Bull Prince Rodeo charm. And that one only gives some stats. Luckily we can kill Baal in terror at least, even if it may takes a couple of minutes. However, killing Baal in dest isn't worth the effort tbh.
