Using FastBreak to break some dirt blocks with bare hands in Wurst 7.15.3.
In-game description“Allows you to break blocks faster.
Tip: This works with Nuker.”

FastBreak is a Minecraft hack that allows the user to break blocks faster than normal. It works by sending a “block broken” packet to the server before the block has actually been broken.


Activation chance

Activation chance
In-game description“Only FastBreaks some of the blocks you break with the given chance, which makes it harder for anti-cheat plugins to detect.

This setting does nothing if Legit mode is enabled.”
Default value100%

The “Activation chance” slider randomly disables FastBreak for some blocks, if it's set to a value lower than 100%.

This works great for bypassing anti-cheat plugins, because they can't really tell the difference between FastBreak and a laggy connection. A few blocks being broken too early can happen in both cases, so these plugins only suspect FastBreak usage if they see a lot of blocks being broken too early in succession. Randomly disabling FastBreak for some of the blocks breaks up the pattern, which leaves these anti-cheat plugins clueless.

A value of around 50% seems to bypass the Vulcan anti-cheat plugin quite reliably, while still providing a much faster mining speed than Legit mode. Though it's possible that even higher values will work, too.

Legit mode

Legit mode
In-game description“Only removes the delay between breaking blocks, without speeding up the breaking process itself.

This is much slower, but great at bypassing anti-cheat plugins. Use this if regular FastBreak is not working and the Activation chance slider doesn't help.”
Default valuenot checked

The “Legit mode” checkbox disables the speed-up effect of FastBreak, but still removes the small delay between breaking blocks. This is useful as a last resort for servers with very strict anti-cheats where nothing else seems to work.
