Notes
While not providing any stats by itself, this ring provides significant stat boosts when worn with other Alien Gear, reaching its full potential with an Alien Weapon and a Protection Matrix. Its effect is unpredictable, but can still help a lot if it triggers.

The Corrosion Core provides a variety of mixed stats leaning towards offense, with the Core at full power arguably being most comparable to a Crown with 20 less HP, 2 less ATT/DEX, and 9 more SPD. It’s quite effective on most classes because of these balanced stats, with the added chance of throwing significantly damaging poisons being a welcome bonus.

During the Alien Invasion event of MotMG 2019, it could also be obtained by trading in 3 stacks of 25 Forax Fragments and a stack of 25 Metal Scrap at the Tinkerer. During the later Alien Invasion 2 event, it could be obtained by trading 2 stacks of 20 Universal Fragments at the Tinkerer.

Trivia
This item, alongside the other Alien Cores, drops in orange bags despite having a BagType value of 6 in the XML, which would normally assign items to white bags. However, the ST status of the item automatically assigns it to orange bags and overwrites the BagType parameter.
