Big Bertha

"" "A relic from the Progressive Era, Big Bertha promises a whooping x12 for any ore through it. Bertha doesn't like repeat customers."

Overview
Big Bertha is a Reborn Tier item that was added in the Secret Update. It was one of three (was supposed to be four) secret reborn items added during this update. An Ore Cannon is required for the ore to be upgraded, since the upgrader itself is higher up. Once upgraded, it will add x12 the ore's value to the ore's value. Ore can only be upgraded once by it because it "doesn't like repeat customers".

This can considered about as powerful as the Lightning Bolt Refiner because it randomly adds 100-700% two times (1400% max in total).

Newtonium Mine is the only dropper in Miner's Haven that is long and tall enough so that ores can be upgraded by Big Bertha straight from the dropper.
