You wouldn't take on whole armies with single or dual Angakok thugs: just beat PD and small batches of freespawn lying around. Fewer provinces = less freespawn and less money.

To take on a whole Rlyeh army, you'd need quite a few Angakoks, but it wouldn't be that hard via bless, items and spells to get each Angakok Quickened, lucky, 20 or more protec, 25 or more MR, reinvigorating, regenerating, 20 Defence. Add AoE weapon, useful shield (vine/eye/charcoal/awe). Then extras depending on the Angakok's magic paths like Soul Vortex, Mistform, Iron/stoneskin, etc.

Set half a dozen such Angakoks loose with a couple of Assartut each on guard commander orders to draw a few attacks (but not so many as to cause a rout if they die). Or just mix a few into a small army.
