ILMUSU'S ENCHANTMENTS
This mod adds more enchantments to Minecraft. It also includes a new mechanic, called Demonic Enchanting, for making enchanting a little bit more interesting without twisting the game too much (and can be disabled through the configuration file).
All the information about mechanics and enchantments can be found here: IlMusuEnchantments Wiki
The main configuration file for the mod is located at:
[minecraft_folder]/config/musuen/mod.properties
It is possible to disable and modify the min and max levels of every enchantment singularly with a configuration file located at the following path:
