EA Ulm advice wanted

[Covenant]

PvK, what sort of blesses are worth stacking on their sacreds? And what function to the Warrior Smiths have? I usually just made as many standard Warriors as possible (10/10 is as cheap as Ulm gets, really). When I was playing against AI's, a F10 bless on the Steel Warriors was good at slicing right through Glamour, but I felt it may have been overkill.
