Astral Ore is a Hardmode ore that generates in the Astral Infection after the Wall of Flesh or Astrum Aureus have been defeated. When the Astral Infection meteor lands and the biome is generated, all existing ore within the infected area is converted into Astral Ore.
Astral Ore requires a pickaxe with a pickaxe power of 210% or greater to mine. However, Astrum Deus must be defeated in order to obtain Astral Ore when mining them. Additionally, after Astrum Deus' defeat, Astral Slimes will begin to drop Astral Ore.
Similarly to how Meteorite inflicts Burning, Astral Ore inflicts the Astral Infection debuff on contact.

Notes
- Astral Ore is immune to explosives even after Astrum Deus has been defeated.
- Astral Ore prevents Meteorites from falling nearby.
- Only the initial astral meteorite impact will convert existing ore into Astral Ore, and subsequent meteor drops, Star Struck Water, and Astral Solution will not convert Pre-Hardmode ores into Astral Ore.
