As you can see, I've locally defined everything instead of using a body template, which seems to work fine. However, in combat, punches from a dwarf tend to treat my creature's skin like, well, regular skin, despite having physical properties of steel and the tissue being defined as granite. I'm looking to make the skin actually tough, like a stone, so that weaker attacks such as punches and weapon attacks from weak materials such as copper just glance away.
I noticed an answer to a similar question at the top of this page. Do I just need to increase the thickness of the skin or should I change the inorganic material from granite to something stronger to get the desired effect?
EDIT: Nevermind, I found out that I should be referencing the stone skin material rather than an inorganic stone material. Whoops!
