McDoom Enchantables

Weapons from McDoom can receive the usual enchantments, such as Mending and Unbreaking, which normally do not apply to them. The mod works by blacklisting the durability-based enchantments that would otherwise affect the weapons' ammo tracking, so the gun system keeps functioning as designed.

The author explains that McDoom uses durability to count ammo, and that enchantments tied to durability can manipulate that count, so the mod excludes them. The author notes that the mod bypasses the restriction through a mixin, and that it exists to enchant McDoom guns while leaving the ammo rules intact.

The mod requires McDoom to work. Files are published for Fabric only, for 1.17 and 1.17.1, and the code is licensed under CC0 1.0 Universal, so it is open source. Both the server and each player must run it, since it is client and server.
