I'm in iron age too (this is my 2d run up to iron).
As I'm a chicken chit, I'm very afraid of the plains, in which I've not set foot yet.
I've seen that most evil souls in the plains are week to spirit damage, obtainedwith the Frostner hammer (club damage). So I've specialized in clubs, masses and now I just Frostner.
Note that Frostner uses lots of stamina.
