A dozen tips for new players:

1. Do the daily+weekly "Battle Pass" quests for rewards, by typing this in the chat: /bp
2. The Overworld has global PvP disabled, keep inventory is on, but players can enable PvP on their own lands if they want; Also, you can't interact with stuff inside someone's lands, therefore claim your lands to easily protect your stuff
3. You can claim 3 chunks for free with /claim and additional claims cost 6000 sats
4. The custom settings for your lands are under /lands
5. There are no ores in the Overworld, but you can go to /mines for coal, iron, gold, diamonds, and sometimes lapis, plus renewable resources like vegetation and others
6. You can buy stuff from the Auction House: /ah
7. To sell stuff in /ah, select a slot in your hotbar and:

• sell all with /ah sell price
• sell a specific quantity with /ah sell price quantity

8. There is mob spawning in the Overworld, but they're not as many as you'd expect in normal gameplay (therefore mob farms are not as efficient)
9. All saplings are available in the mines' courtyard (renewable trees) - make sure you bring Fortune for those rare saplings
10. Use the map, Luke!
11. By using the map, you can see land names. You can teleport to them with /l spawn landname and return home with /home
12. You can also ban players from teleporting to your lands, with /ban playername
