Is this by any chance CBM?
If so you have a far easier solution.

Recruit your best unit: your boulder throwers. Under CBM the boulders are area of effect.

By the way - as agartha you really *love* goblins, hoburgs, swarms, dispossed spirits: Anything that is size 1.

two of them, in the same square as your agarthans will bleed off attacks and boost the survivability of your agarthans.

Just make sure the agarthans are *in front* of the smaller creatures so the smaller creatures will move through.
