From here on out, the only difference between hardcore and normal Wurm is the lack of weapons while you are building your own set of tools and weapons (and armor and whatever else you decide to build). Being able to defend yourself is an undeniable advantage, but tools are far more important to you at this point. Especially an [[anvil]], a [[pickaxe]], a [[hatchet]], and a [[carving knife]].
Since the anvil must be made first, you need to make a [[mallet]]. This tool is only necessary to make the anvil to begin with, and once the anvil is made, its importance diminishes. Fortunately, it is easy to make.
The hatchet and carving knife seem to me to be the most important tools to make. You do need to replace the crude pickaxe with a better one as soon as you can, though. You also need to locate an iron vein to get better quality ore. Iron rocks are always low QL. Also, until you make a [[stone chisel]] and find some [[clay]], you will need to smelt your ore in a [[campfire]]. This is much slower than using a [[forge]], but until you have made some basic iron tools, it's all you have.
This should be enough to get you going. Good luck in the lands of Wurm!
