Hammers

Hammers are tools that are used to break background walls and to create half-blocks and slopes. Higher-level hammers (e.g. the Pestilent Pummeler) have high damage and can serve as weapons. Some can serve as both hammers and axes at the same time, known as hamaxes.

Any hammer may be used to break Shadow Orb s and Crimson Heart s. 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.

Types
There are currently 17 different hammers available in Spirit, 12 of which are Hardmode-exclusive.
