1. Forest: build the foundation
Collect Flint and wood, establish a Workbench/Furnace setup, and use the Adventure Guide when a node opens. The Forest is where you learn mining, NPC housing, movement trinkets and dungeon locks.
Your main progression objective is the Forest dungeon/boss chain that eventually gets you the Forest Pickaxe. Current EA footage verifies the Forest Pickaxe as the tool that opens the next deeper material layer.
2. Snow: solve Freezing before brute-forcing the dungeon
The Snow chapter adds an environmental gate: Freezing. Official 0.15 notes say cold water, permafrost and the Snow Dungeon can trigger it. The Frozen Heart grants immunity.
The Snow Boss is made of four pieces. It attacks by using one piece to crush you; that active piece is the weak point. Destroy all pieces to finish the boss. Current footage then shows the Ice Pickaxe enabling the Palladium tier.
3. Desert: Palladium → tower dungeon → Worm
The Desert is new enough that older wiki dungeon lists are incomplete. Official 0.15 notes describe a multi-floor tower dungeon with spawners, collapsing-ceiling mechanics, a dungeon lock/key system and a final summoner.
The Desert Worm spawns outside in the desert after you activate the final summoner. It can fly and splits into three segments at 50% health.
Check the Adventure Guide when the route stalls
Open the Adventure Guide added in 0.15 and check the next node against your current chapter. If the blocker is a key, cold damage or a dungeon mechanism, use the chapter guide above. The weather and fishing features shown in the September progress post are upcoming work, not confirmed additions to 0.15.14.
