Pwnhammer

The Pwnhammer is a Hardmode hammer that is able to destroy Demon Altars and Crimson Altars, blessing the world with one of the six Hardmode ores. It is always dropped by the Wall of Flesh. The Pwnhammer has a sparkle effect when used, giving off a good deal of light even in total darkness. Altars can only be destroyed in Hardmode worlds, ie. worlds where the Wall of Flesh has been defeated.

Each Altar spawns new amounts of Hardmode ores. The first destroyed Demon or Crimson Altar blesses the world with Cobalt or Palladium Ore, the second with Mythril or Orichalcum Ore, and third with Adamantite or Titanium Ore. The Ore option chosen for each Altar is randomly determined upon world generation, similar to the naturally-spawning ores. Subsequent destroyed Altars repeats this process, generating more Cobalt or Palladium, then more Mythril or Orichalium, then more Adamantite or Titanium.

Trivia

 * The name is a reference to Super Mario Bros. X, a game Redigit has previously worked on.
