Trading is unlocked by building the trading post in the crafting menu. It allows you to trade with other players as long as they are on the same server.

The trading post costs 100 gold bars and you have to be crafting level 100 to build it.

UPDATE: If you created an account after DECEMBER 5th, 2019, you have to have bought blood crystals to use the trading feature. You can still use the player market Edit

Trading Edit

Trading is done by tapping on the trading post in your house menu. To trade, you have to find a player willing to trade. The mobile chat might help in this instance. Just ask if anyone wants the item you are willing to sell and name your server.

You can trade most in game objects. There are a few that cannot be traded:


-Blood crystals (except purchased ones)

-Crystals from opened geodes.


-Tools (w/ or w/out gems socketed) ???

If you have an item and don't know what it does, don't sell it! Instead, check the link below:

UPDATED 25-11-2019 . Feel free to edit if it is wrong. Values may not be exact.



You can sell stuff for blood crystals.

You can only buy things with purchased blood crystals. Edit

Every item has a min price, depending on the item. The max price for any item is 2,000,000 BC.

You may sell up to 3 items at a time.

As of right now, you may only sell items in your equipment tab.

However, you get an error when you try to sell bird feed or a rusty sword.


Trading Discord Edit

To trade with other players you need to be able to communicate with them

An official discord has been set up to facilitate trading free to use it or share with others

Fun Fact: If you try to trade with yourself, it will ask you "why?"
