Indeed the Zombie trait isn't as good as it seems to be.
I have my battlemage invested in geomancer. Only those ooze spells can be the sort of healing so far, or you craft some poison stuff.
Yes you will welcome poison damage and standing on oozes, but the healing is way too slow. Even a minor restoration from Jahal heals two times faster per turn. And don't forget if someone attacks you with fire all the ooze around you will explode and you take huge fire damage like any others.
