Lucare's Uncertainty

"An interesting furnace with an upgrader beam in front of it. Uncertainty in the beam can make the ore negatively impact the furnace itself."

Lucare's Uncertainty is a limited time furnace that was obtainable from rebirthing during the duration of the Alien Invasion Event.

Trivia

 * This item has been heavily fixed by Guest, as the math.random function didn't like negative values, so he ended up doing a normal math.random function, and multiplied it by -1 to get the negative amounts.
 * The upgrader itself is insanely powerful, as the beam can reach conveyors if placed on the side.
 * This furnace was the first modded item inside of boxes.
