The macro "Sheld breaker" for "Minecraft" can be downloaded and used on simple mouse and keyboard. Installing the macro is quick and easy in the Keyran program and increases your skill level in the game, if you follow the instructions!
This macro allows you to break the shield when you press a certain command on the keyboard. I added 3 clicks for reliability, if you don't accidentally get on the shield. If the macro doesn't work, try increasing the delay between clicks.
