Soul Gate's critters are not lifeless, either, so life drain works nicely. (Which is why Soul Gate is in my opinion much worse than Ashen Empire. Alongside of course SG having less hp in the horde and less damage potential.) In fact, they aren't mindless either, so fear and awe should work against them, too.

Also, in theory a dude with high attack and a magic weapon should repel the dipossessed spirits to death when they swarm him, right? Could be considered, in case you don't happen to have fireshield available.
