This is the exact opposite of sparkly dust from a passing comet. It seems to whirl backwards like a tiny galaxy. Perhaps if you collected enough of it, it would merge into an astonishingly valuable solid mass!
This item never drops any seeds.

Antimatter Dust is a Night Of The Comet item. It randomly spawns at the world just like Comet Dust but more rarely. This item can't be spliced, but when you have 200 antimatter dust, you can combine them to make a Galactic Starseed.
