Winter Mining Special Strategy
Winter is the best time to rush the mines — since you can't plant outdoors, you can spend all day in the mines:
Recommended winter schedule:
6:00 Wake up, harvest greenhouse
6:30 Head straight to the mines
6:30-13:00 Descend (bring food + bombs)
13:00-17:00 Collect ore + geodes
17:00-18:00 Gather obsidian near mine entrance
18:00-19:00 Go home and sell goods
19:00-22:00 Smelt ore + processing
Winter mining goal: Reach floor 120 before the end of your first winter, unlocking the Obsidian Edge + all elevators.
