Frequently Asked Questions

How do you learn an item in the Transmutation Table?

Place the item into the burning matrix slot of the Transmutation Table to convert it into energy value and permanently record its blueprint for future transmutation.

How do Energy Collectors generate passive energy?

Energy Collectors generate energy over time when exposed to sunlight or bright light, routing accumulated power into adjacent relays and condensers.

What does the Energy Condenser do?

Place a target item into the condenser lock slot, and the machine will consume incoming energy to continuously duplicate identical copies of that item.

How do you craft Dark Matter?

Combine eight units of Aeternalis Fuel with a diamond block on a crafting table to synthesize a piece of Dark Matter.

What is the function of the Dark Matter Pedestal?

Placing alchemical accessories atop a Dark Matter Pedestal activates continuous area-of-effect abilities across nearby chunks, such as magnetic item collection.
