"The Ore Supernova grants a massive upgrade to all dropped ores when activated. Ores can only be upgraded by it once."
The Ore Supernova is a Slipstream-tier Ore Pulsar variation where instead of removing ore, it upgrades them by multiplying their value by 10x, then adding $1k. The item also has an extremely lengthy reload speed, taking just over a full minute to become active once again, you can easily bypass this drawback by picking up the item and placing it down again. As the description states, the Ore Supernova only upgrades ore once. It also replaces the Destroy all ores button with Upgrade all ores. Prior to the 2017 Easter Event, the multiplier was x5.
