For it to work, it is necessary to have obsidian in the first slot of the hotbar and crystal in the second slot of the hotbar, otherwise the macro will not function. The macro is executed very quickly, in about 100 milliseconds. The recommended mouse sensitivity in the game is 100%, and the scroll speed should be set to 1.00. The macro is activated by pressing the V key. Update: The working speed of the macro has been increased, as well as the number of errors has been reduced.
