Hammers

Hammers are tools that are used to break background walls and to create half-blocks and slopes.

Higher-level hammers (e.g. Luminite Hammers) have high damage and can serve as weapons. Some can serve as both Hammers and Axes at the same time, known as Hamaxes. New players do not spawn with a hammer. Some hammers cannot break/destroy all backgrounds. (e.g. Wooden Hammer)

Any hammer may be used to break Shadow Orbs and Crimson Hearts. A Pwnhammer or better is required to destroy Altars, however this is only possible in a world where the Wall of Flesh has been defeated. When attempting to destroy one with a lesser hammer, or prior to defeating the Wall of Flesh, the player will take damage equal to half their current health, and the Altar will remain unharmed.
