Crafted myself a grappling hook and went on an iron and fossil collection rampage
I love the way music merges with climbing and watching the landscapes, truly immersive. I would do that for hours!
Then I went to a cave which have been spotted by one of the players (he gave me a location marker). Went about hundred blocks underground, found myself some resources, then noticed there was a light far away - I went to that light, used my grappling hook and BAM! I'm now on a beautiful cold lake
On my road home I found a cliff wall with TONS of coal and tech fragments. Gotta dig 'em some day Or you can ask me for coordinates to help me dig it and split the treasure
