Summary0001110: impact yield and impact fracture the same for all metals, unbalances combat
DescriptionAs the summary says, impact_yield and impact_fracture are the same (1080000, stainless steel) for all metals. This means non-steel armor protects too good, and nonsteel weapons are too strong.


For details on the impact this has, see here:

Additional InformationMy own information is purely based on the raws, this forum post and observations during gameplay. I did not do any tests that included changing those values myself.

I did a bit of research on what these values should be, and determined that for metals compressive strength ~= tensile strength. I copy/pasted the shear yield and fracture values into the impact yield and fracture tags, and arena mode showed this to be far more reasonable.

There have been a couple of threads discussing proper raw values, most notably these:

While I'm infodumping, there's a useful thread with test results from arena. It describes several other material and combat related issues:

I've updated all the metals so that they have Dwarfoloid's suggested values, and I've made compression/impact a fixed multiple of the tensile strength (because it was generally higher for iron, and there's very little data available).
