I haven't tried this build (fooled around with Machaka a few times, I think my last attempt had W9 actually, which was fun in SP for sure!), but it has some shiny points.
Imprisoned Master Lich
4E/4S/9D/2B
5Dom 3O/H3/G3/Mis2/M1
If you drop 1 scale, you can bump that to 7Dom, which I would probably do, just make it G2 and 7Dom. You can get the same effect if you drop the Blood. However I thought the Blood was interesting, as he can not only forge Dwarven Hammers, but Blood Stones as well. Plus if you are the sort that is inclined to try to build a blood economy nearly from scratch, that can open up a lot of options altogether. Plus the Astral is enough to kick spider MR to more acceptable levels, AND is easily leverage-able
to anything Astral you could want (if you can find enough Pearls).
I know you don't seem to like imprisoning, but in MP it's usually not worth the cost of 2.5 scales if you're already shelling out for major blesses.
If you've never tried D bless with a unit like the spider, you should give it a whirl. AN damage is <3
