Plugin Shieldstunfix

Shieldstunfix, restore tactical shield combat

Shieldstunfix is a lightweight Paper plugin for Minecraft Java servers running 1.21.x. It restores the vanilla shield stun behavior affected by Paper, addressing bug MC 268147 and removing the unintended immunity window that can follow a shield disable.

With this fix active, an axe can disable a raised shield and the next attack can connect as expected, restoring knockback, timing, and counterplay to PvP. The plugin requires no commands or configuration, keeping the experience simple and focused. At BoxToPlay, we recommend it for server owners who want more responsive, skill based shield combat without changing other gameplay mechanics.
