Ermor can counter SCs in many ways... Most of them involve battle magic.

MR saving throw spells like Paralyze, soul slay, Enslave Mind and opposition will eventually cause a SC to miss his save... then he's as good as dead.

Against undead SCs Dust to Dust does great damage and is unresistable. Shadow bolt automatically feebleminds people around where it strikes, which can mess SCs up. Another way to fight SCs is via thugs- tough characters geared up for maximum damage rather than survivability.

It might be too late (I don't know what happened in Abysia, no scout coverage there), but it can pay to basicly look through the dominions spell list with a specific purpose in mind (say, countering a King of Elemental Earth) and check which spells (even summons) can work for that goal.
