Pwnhammer

The Pwnhammer is a Hardmode hammer that is able to destroy Demon Altars, blessing the world with one of the three 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.

The first destroyed Demon Altar blesses the world with Cobalt Ore, the second with Mythril Ore, and third with Adamantite Ore. Subsequent destroyed Altars repeats this process, generating more Cobalt, then more Mythril, then more Adamantite. You can only destroy demon alters in worlds that you have already beat the Wall of Flesh in.

Trivia

 * The name is a reference to Super Mario Bros. X, a game Redigit has previously worked on.
 * The Pwnhammer is the only hammer in the game that can't be crafted (This includes Hamdraxes & Hamaxes).
 * The Pwnhammer & the Hamdrax are the only two tools capable of destroying a demon altar.
 * 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.
