The Lava Spill Refiner is the first obtainable card upgrader in the game. It has a 20% chance of being pulled from any Galactic Supreme Pack opening. It is one of few Normal mode items that can cross over into Extreme mode, and its low power consumption of 8.5kU allows for its use almost instantly.
This upgrader will only work on cards that come directly from depots. Attempting to "spill" a manually dropped card will not double it. The same also goes for alloys that come out of Alloy Factories, since they can use only for Tier 1 cards.
This upgrader may have been based on an old bug where Resource Cards could be upgraded.
