MA Ermor advice please

[Aezeal]

I don't need to know all the details, I like to find out stuff myself too, but I don't want to make ALL the basic mistakes either

I've never played an undead race before and I have no idea how ermor (in any age) plays out

I'd like a few pointers in the right direction about pretender build (incl scales etc)

-which blesses would be best for ermor and why
-would you play ermor MA with blessings
-which scales are important and which are not
-are there any scales I should put on the negative to save points?

a few suggestions for pretender builds would be nice. I'm doing a SP to practice for the MP I voluteered for

my current build is
Imprisoned Lich queen
A4D9
income 1 or 2
prod 2
heat 0
luck 3
growth 0
magic 0

dominion 5

I took high prod cus I read the quality units have high resource costs. Even though I'm imprisoned I only have a 9+4 bless because I'm very hesitant to take negative scales

I have no room for higher dominion in the build as it is and I never take a lower dominion than 5 either (like with the scales I like to be a bit save)

the only thing I might think about is drain 2 for 80 extra points which I would invest in higher astral and 1-2 dominion

another option would be death 4 astral 9

is the death blessing better than the astral one
(I usually play "good" races with earth/water/nature blessings so ermor is a whole new experience for me for my first MP too..)
