I just got done playing a Warforged Juggernaut character in an Eberron campaign and I loved it.
My only complaint about the Juggernaut was the medium BAB progression.
My tactic was to bull rush opponents and impale them on my enchanted armor spikes, then grapple them and cause more spike damage.
Has anybody else played with a Juggernaut? What were your thoughts?
I wonder if Paizo will introduce a warforged type of creature in the upcoming bestiary.
Aside form weapon focus feat and such I don't know what might help you, aside from magic.
Updating Warforged would be easy enough. I'd drop one of the stat penalties, myself, and leave it at that. Paizo could probably update Living Construct without getting in trouble, assuming it needs it. I was thinking that some of the Barbarian rage powers were a nod at converting Shifters on the sly.
