  • If the condition for getting Fallen Stars or Astral Ore from the Extractinator is not met but the player succeeds in rolling either of those items, the vanilla loot table is used instead.
  • If the condition for the tier 2 and 3 Hardmode ores are not met, the highest unlocked tier is extracted instead.
  • Unlike Silt and Slush, Novae Slag is not affected by gravity.
  • Although both Silt and Slush can get converted into Novae Slag, purifying Novae Slag will only turn it into Silt.
