Palladium Ore

Palladium Ore is a new Hardmode Ore that was introduced in the 1.2 patch.

Hardmode Ores are generated upon destroying a Demon Altar or Crimson Altar with a Pwnhammer. They are immune to all types of explosions.

Palladium is the replacement for Cobalt.

Palladium requires Molten Pickaxe to mine.

Palladium is stronger than Cobalt, even though they are both replacements for each other.
