Even if you were wearing full plate, the helmet is the weak point, right? You can't really spread the force out that much, so the brains splat or the neck snaps if hit right with a blunt object.
About the adamantine casings proposed, can dwarves actually attain temperatures necessary to melt adamantine in their forges? Making thin sheets to cover an existing lead hammer's head might be more easily done.
Along the same lines, will item modifiers like menacing with spikes ever affect the damage of a weapon? It might be cool in the future if a warrior became fond of a copper sword and refused to fight with any other weapon, but you could send it back to the forge to add spikes to the pommel to upgrade the sword a little. It would probably create a micromanaging nightmare though.
While I was on wikipedia looking at war hammer stuff I came across this page about surface or case hardening.
Does anyone know more about this?
For those that don't want to look through the page:
What does case hardening do?
Case hardening involves packing the low-carbon iron within a substance high in carbon, then heating this pack to encourage carbon migration into the surface of the iron. This formes a thin surface layer of higher carbon steel, with the carbon content gradually decreasing deeper from the surface. The resulting product combines much of the toughness of a low-carbon steel core, with the hardness and wear resistance of the outer high-carbon steel.
How was it done historically?
The traditional method of applying the carbon to the surface of the iron involved packing the iron in a mixture of ground
bone and
charcoal, or a combination of
leather,
hooves,
salt and
urine, all inside a well-sealed box. This carburizing package is then heated to a high temperature, but still under the melting point of the iron, and left at that temperature for a length of time. The longer the package is held at the high temperature, the deeper the carbon will diffuse into the surface. Different depths of hardening is desirable for different purposes: sharp tools need deep hardening to allow grinding and resharpening without exposing the soft core, while machine parts like gears might need only shallow hardening for increased wear resistance.
Seems pretty dwarven, and I believe its the right tech era, 14th-15th century, or late medieval. It would also work well in an item upgrade system, in this case upgrading iron items.
