So, this zombie boss is not working for a variety of other reasons outlined in other threads.
What I’ve decided to do is just keep things simple. All units in 3 hex area become get 2 buffs. They are Immune to Pin, Push and Pulls (Move compulsions) and gain +X extra strength.
I will let Blighted Pea have a think about what the +x should be but I have it set at 5 for my testing.
I think That should be scary enough!
