Ion Cube (Below Zero)

Ion Cubes are a type of synthetic crystal created by the The Architects. They can contain massive amounts of energy equivalent to a 'small nuclear detonation' in a stable state. Ion Cubes are used to power certain Architect devices. They can be used to craft Alien Tablets, as well as powerful Ion Batteries and Ion Power Cells. Ion Cubes are also the only power source of the Tether Tool.

Ion Cubes can currently only be found within Sanctuary Zero and next to both Obelisks found in the Arctic Kelp Caves and the Deep Twisty Bridges. A Large Ion Cube Deposit can be found in the Arctic Spires Cache. Like all large resource deposits, it can only be mined with the Prawn Suit Drill Arm.
