A macro, as you can already guess from the name, is a sequence of actions that are automatically performed when certain keys are pressed. For the macro to work correctly, you need to reset the default keyboard settings. It is important to have a sacred sword with you, as it is an integral part of the macro. 
It is also recommended to equip the Great Jug's Arsenal (or other damage-enhancing arsenals) to ensure a sufficient level of damage. Otherwise, the macro may not work properly.
(The 5-second delay after pressing the E key is adjusted depending on the speed of your disk. It is recommended that you change this setting).
