This mod adds 31 new enchantments to the game. Most are available through standard enchanting, though some require more complicated methods of obtaining them (information in spoilers).

Accumulating can only be obtained as a rare reward from fletcher villagers after succeeding in a raid.

Obscuring can only be obtained as a rare drop from killing endermen with a pumpkin on your head. This increases with looting.

Pork chopper can only be obtained as a rare drop from killing piglin brutes. This increases with looting.

Precision can only be obtained by combining two enchanted books only containing multishot and marksman.

The mod allows for modification of vanilla Minecraft behavior through a config.

Shields are able to be enchanted at enchanting tables, as opposed to solely through enchanted books, by default. This can be disabled.
This mod's crossbow enchantments work on bows and bow enchantments work on crossbows, but they are not obtainable via enchanting by default. This can be enabled.
Piercing can be obtained on bows via enchanting and work on arrows, but this behavior is disabled by default. It can be enabled.
Power, punch, and flame can be obtained on crossbows via enchanting and work on arrows, but this behavior is disabled by default. It can be enabled.
Arrow damage is determined by arrow velocity. The draw enchantment increases arrow velocity, increasing arrow damage. Draw arrow damage is reduced to account for the increased velocity by default. This can be disabled.
The sniper enchantment's zoom is relative to the player's FOV scale by default. This can be disabled to have a consistent zoom, no matter the FOV scale.

This mod has a wiki!
