What it does

The enchantments are the mod's main content, and the author chose them to explore a few combat ideas, some of them borrowed from other sources. The current build adds three enchantments and the author describes the mod as a hobby project. Items and blocks are noted as possible future additions, but none are part of the current release.

FPS Killer raises a weapon's damage based on the player's frame rate. The settings are adjustable: the mod can make higher FPS raise damage or lower FPS raise damage, and the maximum bonus and the effect of each frame can be changed. These values are read from the config file, and the config can also be edited in game. Mercy Curse makes an attack that would exceed the target's remaining health leave the target at one health point, and the attack that finishes the target is then ignored, so a target cannot be killed on the next hit.

Linweiyun is released under the Creative Commons Attribution Non Commercial 4.0 license, which is not open source. Source code, an issue tracker and a wiki are public. It runs on the client and the server, so both need it. The latest NeoForge file is 0.0.7 for 1.21.1, dated 2025-08-02.

Key features

  1. FPS Killer enchantment

  3. Newton's Third Law enchantment

    Makes the attacker take damage equal to the target's before armor is applied, and can knock the target's weapon or equipment loose.

  4. Editable configuration

    The values for the enchantments can be changed in the config file or inside the game.
