Void item (purple)
Your special skill (R) gets one more use. Turns your Fuel Cells into this. Each extra one, another use.

Stacking: Each copy adds the same, no cap.
Watch out: It also lowers the special cooldown (the game does not say so).
It is the void version of Fuel Cell: pick it up and every copy of that item turns into this one.
