KillEnchant

This mod change the level requirement influences in the enchantment table, but without changing the level or lapis lazuli consumption. This mod is pretty much tied to a event provided by NeoForge and its methods.

The higher vanila enchantment level is 30, this score will increase or decrease by a default 6 if you kill/get killed by another player or use the enchant_levelup item, these numbers can be configured in the configs.

You can go up to 110 and down to 1 with KillEnchant (any higher or lower would break the system), I recommend using BeyondEnchant with this mod. Despite beliefs, the 1.21.9-1.6.2 version of BeyondEnchant can be loaded into NeoForge, although some of its features fails to load properly.

Read the wiki for more informations:

“The level requirement influences the quantity, type, and level of enchantments instilled in the item, with a higher experience level generally resulting in more and/or higher-level enchantments. Nevertheless, there is a significant random factor, and even a level 30 enchantment (the maximum) doesn’t guarantee more than one enchantment, or even that enchantments are maximum strength — a level 30 enchantment can still yield Fortune II or Efficiency III alone, for example.” https://minecraft.wiki/w/Enchanting_Table
