Description:
'It allows your body to shatter in space.'
On use gives the "Void Core" buff (5 hours), which makes your abstract biome location {for the items like a biome tokens from the other mods} an EVERY. SINGLE. ONE. simultaneously, which is _probably_ good for fishing, i guess?

Materials:
Core of Beach
Core of Sky
Core of Corruption
Core of Crimson
Core of Dungeon
Core of Desert
Core of Underworld
Core of Hallow
Core of Jungle
Core of Snow
Core of Meteorite
3x Dark Fragment
Protip for obtaining most, if not all, of the cores: just summon goblin invasion (i think it'll work with other invasions too, it's just specific that all mobs of invasion walk on feet so they can spawn on floating arenas with multiple rows), build specific arenas if you need to, and then proceed to killing the mobs from invasion (and spam "Vacuum Items" from cheat sheet). 100% drop. Maybe you can even move between biomes to try and get some more cores for 1 invasion.
I think they drops only in hardmode. And please, don't try and farm the meteor heads.
