Nins innovation

The initial version introduces 19 affixes and 15 enchantments. The affix values and enchantment acquisition methods can be customized through the configuration files. Additionally, you can use the mod’s built-in /truenins command to apply affixes to items.

In fact, these 19 affixes work by checking an item’s tag — the tag name is the affix name. I’ve listed them all in a book, which you can obtain using /give.
You can use these affixes and enchantments to enhance your gear or customize your modpack. More will be added over time.
