The Fantastic Platinum Lunar Cell is a VERY overpowered item. It uses the power of the moon which only reflects the sunlight and so it should work better at night than at day!!??.. okay just thinking too much!

This fantastic cell produces 1T energy at night. It's only obtainable through Supreme Packs at an extremely rare rate (around 2% chance).

There is a Progression and a solar variant of this cell, the Platinum Concentrator Solar Cell, with the same 1T energy production. Using both of these cells will allow you to have at least 1T energy at all times.
