FAQ
Where can I find Hardwood?
Hardwood comes from larger, darker trees found in the Foothills biome and beyond. The starter island only has regular Wood trees — you need an Iron Axe to harvest Hardwood efficiently.
How do I get Tanned Leather?
Tanned Leather is processed from Rough Hide at a Tannery station (requires Foothills progression). As more players reach mid-game, the exact recipe will be confirmed.
Where can I farm Rum Bottles?
The best source is pirate camps and smuggler stashes. Clear camps, loot all crates, and revisit after they reset. Shipwreck debris on beaches also occasionally contains Rum Bottles.
