About this Mod
No delay between hits anymore, just like 1.8!
You can still use the offhand, shields, crossbows, etc… and any other mechanic after 1.8
Multiplayer Compatible!
Axes:
Axes have been nerfed back to their original 1.8 damage (with the exception of netherite axe obviously):
- Wooden Axe: 3
- Golden Axe: 3
- Stone Axe: 4
- Iron Axe: 5
- Diamond Axe: 6
- Netherite Axe: 7
Blocking
You can now block with any sword, just like 1.8!
Blocking reduces any attack damage towards the player by 40% and reduces the knock-back in half
Enabling/disabling the mechanic with a simple command!
Do NOT use /datapack disable without first disabling the 1.8 mechanic!
Enable (is on by default)
/function instant_pvp:enable
Disable
/function instant_pvp:disable
Switching between the two will automatically:
- Change the attack speed of players
- Enable/Disable the blocking ability of swords
- Change the damage dealt by axes.

Instant PvP officially supports datapack, fabric, forge, neoforge for Minecraft 1.21.4, 1.21, 1.20.4. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Instant PvP – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Instant PvP consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
