What i do:
- Get to campfire asap to get rested buff
- First "base" in a derelict shed to craft stuff or sleep night if needed, no hoarding except flint and hides. (you need at least two stacks of flint, which is only found on meadow shores)
- Kill first boss with no real base. Stack him on the stones.
- Go black forest and make first base somewhere close to tin, cooper and boars (from runestone).

Its not bad making first base early but you unlock many interesting building pieces AFTER getting to bronze (next biome after first boss), so i would advise not going all out too early.

Also dont build too close to black forest if you dont want to be flooded with enemies whenever a tree falls.
