Forgot to mention, the facing on my Spirit Hosts may be a bit misleading. Dunno why it shows them as pointing forward even though I turned them to face the sides. If you zoom in you can see their true facing.
Bah made my first obvious mistake, forgot to turn my treeman slightly, so he could cast treesinging on the Vargheists. It with blood forest rules could have made some damage. Still getting used to magic line of sight, in the good old days there was no such limitation to the spell.
