From my experience attack procs are very underwhelming, not enough aoe for fast clear. In fauztinville they are extra weak, because neons are immune and they block a lot of projectile based spells, before they die. If you wanna approach every single little pack of necrobots, after rest of enemies dies, and melee them one by one, via spell procs, thats gonna be just slow.
As I mentioned earlier, give pala sssu holy lance, and it basically creates mr painless effect, or necro shaad scythe, whole screen of punishers, where they carry enough damage to quickly 1 shot necrobot. I guess we should be happy such item exists, because not every build has this luxury.
Fauzt is a good farming spot, and a challenge, to figure out build that can clear it.
