Break Denyer
Minecraft Java mod. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgeThis mod will prevent non-op players from breaking and placing blocks on server. This allows servers to be made in survival/adventure mode, but not have the risk of the players going around breaking all of the glass blocks, but still being able to kill mobs, craft weapons, etc.
