Astral Ore

"The seal of the stars has been broken!"

Astral Ore is a Hardmode ore which generates in the world after defeating the Wall of Flesh or Astrum Aureus, converting many blocks around it into the Astral Infection. A Picksaw or a pickaxe of a higher power can mine it, but only if the Astrum Deus boss is defeated. Additionally, after Astrum Deus' defeat, Astral Slimes will begin to drop Astral Ore.

Similarly to how Hellstone inflicts Burning, Astral Ore inflicts the Astral Infection debuff on contact. Up to 60-70 bars can be mined from one astral meteorite.
