I am playing at similar pace. Not sure of exact day I killed 1st boss. But likely day 100-115ish. Its day 150 something for me now and have had 2nd base at edge of Black Forest. Just on Meadow side. That base has enough fires/ torches and whatnot that I had my 1st "The forest is moving" event there. About 10th overall maybe, but 1st at new base. That event is much more fun here because that base is much smaller and everything condensing nicely for my arrows.

Only thing I noticed as far as progression, When I first built my 2nd base at edge of BF, Hadn't seen a troll there. That was about turn 120-125. Now there is a troll just across border about every day. Likely everyday if I venture across. Another one just 200 scale meters east of me. Killed one just beyond that. So Trolls are lurking big time in BF now about turn 160 while just 10 days ago nothing. I don't know if the spawn rate for them ramps up at turn 150, or if it started a cycle once I entered BF the 1st time or what,

They do seem content to remain in BF. I lured one across to my base, but once it found no way across moat it went back to its roam area. Had too many trees up still to get shots as it went away.

So I can just ride it out here as I get more XP I guess. More stuff seams to be spawning. Seen a nest not far in the BF that I didn't notice before.

I don't venture far into BF. I can take Troll by itself, but lots of stuff joins in there that isn't in the meadow. Terrain is much rougher also and easy to find a cliff where you can get cornered. I want to lure a troll at a time and complete the Troll armor before I target nests.
