Well, the great Tien Chi resurgence to dislodge the Pangaean oppressor is going well, but our sister Ulm is being invaded by not one but two masses of nasty undead. One army has a Saurolich and about ten Marshmasters summoning hordes of skeletons. The other army has almsot 600 Ermorian undead.

Does anyone have any advice on how to resist such an onslaught?

Counts with skull staffs casting wither bones would work well if you have the research (and the casters and items). Solar rays from members of the third tier and astral random fortune tellers. Dust to dust from revenants and death random fortune tellers. And of course plain old priests.
