Just built a WF Fighter with the Adamantine body as I know my AC will be fairly poor but figured I could make use of the DR and even bump it further through some extra feats I'll likely have. It doesn't seem to show up in the combat log as actually applying though.

I've never had a WF with the Adamantine body before, is this normal?
I'd hope they don't start equipping the Cultists with Adamantine weapons starting at level 1
