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.

Each altar runs on its own rotation of ore spawning. 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 ores received per altar are randomly determined upon world generation, similarly 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. You can only destroy altars in worlds in which you have already beaten the Wall of Flesh.

In version 1.1, the Pwnhammer was the second best hammer in the game, coming just shy of the abilities of the Hamdrax. In 1.2, the Hammush was introduced - a mushroom-themed, more powerful alternative to the Pwnhammer, if one has sufficient coins. However, the Hamdrax was changed to remove its hammer function and consequently renamed to merely the Drax, and a new hamaxe was added, namely The Axe. If one can acquire The Axe, it is vastly superior to both the Pwnhammer and the Hammush. It is the only hammer that can destroy a demon altar.

Trivia

 * The name is a reference to Super Mario Bros. X, a game Redigit has previously worked on.
 * The Pwnhammer & the Drax used to be the only two tools capable of destroying a demon altar despite the fact that the latter does not have the former as a crafting ingredient.
 * If a player attempts to destroy a Demon Altar with the Pwnhammer before the Wall of Flesh has been destroyed, it will behave like a normal hammer; the player will lose half of their current health.
