Cursed Anvil Enchanting

The mod gives curse enchantments a purpose in anvil work. On a default iron anvil, enchanting asks for more experience, and a higher enchantment level raises the chance that a curse is added. The anvil changes colour from orange toward black and darker orange as that chance grows, so a player can judge the risk visually before committing. A netherite anvil asks for less experience and removes the chance of a curse, but it is unbreakable, and its use causes more fall damage. It is balanced as expensive to craft, with three netherite blocks per anvil.

The mod is meant for modpacks and progression built around the anvil. The author describes it as a way to make the anvil both overpowered and balanced, and the configuration file lets server owners change how the mechanic works, including the colours and the enchantment cost text. On iron anvils, several enchantments such as mending and infinity can be set to always carry a curse, and the author recommends pairing it with Majrusz's Enchantments, which adds new curses.
