At this point you should be able to mine tin and copper with the antler pickaxe, and grab a few surtling cores from the burial chambers to make a charcoal kiln/smelter to smelt that copper and tin, and finally make bronze bars. Aside from making bronze gear you can also make bronze nails which will allow you to make a Karve, which will serve you way better than a raft.

For trolls you may want to make Fire arrows, they use fairly common materials, and you will need them for the second boss anyway.

Be sure to stock up on decent food! At your game progress I'd suggest cooked meat/neck tails/queens jam.
