Thanks for the tips, much appreciated. Not 100% how to format this better but to go down the list of clarifications/further questions:
1. Can I swap classes (make a new character, presumably) and play on the same world? I can't help but be a bit attached as I have some boars, chickens, and bighorn sheep in pens and was working on animal husbandry. The lower health is definitely a struggle though so perhaps I will swap and start a new world. The only thing I don't love is making arrows but I suppose I can just make them out of copper to avoid having to do too much arrow knapping.
2. I think this is the key that I am missing. If caves are prohibitively dangerous until better equipped I will simply avoid them until later. I had somewhat suspected this was the issue but am a bit sad to hear I was correct. Not to get too into the weeds but I do think this is a bit of an odd design choice but I can respect the vision of the developers, I suppose. Thank you for the tips on mining, I'll give it a try and see if my high readings lead me to some successful tin gathering.
3. This makes sense and I had anecdotally noticed more spawns on high rift activity days. Good to know I wasn't hallucinating.
4. On this, if I had opted instead of making a full set of tin bronze chainmail (I am wearing head, chest, and legs) to make a bronze anvil in that case could I have "skipped" up to iron without spending much time on tin/bronze age? Just curious, the ship has sailed as I don't think I have enough tin left from that lucky early node to make an anvil now but I definitely had the option early on, considered it and opted for the armor assuming it would pay dividends to be equipped well enough to mine my own tin. In hindsight, perhaps not the optimal choice as if VS is anything like the real world the difficulty with iron should (broadly speaking) be forging it rather than finding it.
