Pwnhammer

The Pwnhammer is a hammer that able to break Demon Altars, blessing the world with one of 3 of the new ores; Cobalt Ore, Mythril Ore, and Adamantite Ore (in that exact order). It is dropped by the Wall of Flesh.

Note: The Wall of Flesh must have been defeated on a map for the Demon Altars to be destroyed. Otherwise the player will take damage like they were trying to attack a Demon Altar with any other hammer.

Its appearance resembles the Excalibur, so they are likely to be crafted from the same material/found in the same area/dropped by the same enemy.
