Haven't encountered a super bless strat in MP yet, so just throwing out some ideas.

What about Mind burn + Communion? Thau lvl 2 should be able to dish this out if you can recruit astral mages. So Ermor, pythium and C'tis should be able to paralyze and kill expensive sacred units with MR below 13...

Nature mages gets Vine arrows at Evoc lvl 2. does 14+ damage and entangles the enemy.

For low strenght enemies (Mictlan?) Conjuration 1 gives tangle vines.

Thaumaturgy lvl 2, Bonds of fire. Requires F1.
Alteration lvl 2, Earth meld. Req E2
Alteration lvl 1, False fetters, Req A2

Combine this with some long range attacks like archers, or artillery mages to actually kill off the Blessed troops.

So basically Blood and death are the paths with problems if you cannot get lvl 2 mages of a certain path to spamm the above spells. In theory that is....
