The Jacksoning Combat Tweaks
by mpfaff
The Jacksoning Combat Tweaks changes how hits register on Fabric servers, removing damage invincibility frames and altering knockback timing for players and mobs.
What it does
Combat behavior on the server changes once the mod is installed: damage invincibility frames are removed, and players receive knockback invincibility frames for a set time during which they cannot be knocked back. Certain items carry the combat tweaks and can bypass the knockback cooldown and invincibility frames, which allows very rapid combos. Other mobs also receive invincibility frames, so their combos can continue without interruption. The mod requires Fabric API, and it bundles Polymer. Files are published for Fabric 1.21.4 only, with 0.1.0 as the latest file, and the environment is server-side only, so players join without installing it.
