To use this macro, you need to bind two keys: W to activate the Astral ability and Space to activate the Meteor Hammer ability. First of all, make sure that your character has four levels in the Astral ability.

To use the macro correctly, place the mouse cursor on the enemy. Then press and hold the key that the macro is bound to. It is important to keep holding the key while performing the Astral and moving the cursor to the area of action of the Meteor Hammer after the Astral.
Make sure that you use quickcasts (quick application of abilities without the need to select a target) and enable the «Stop abilities with a separate key» function in the settings.
However, keep in mind that this macro will be useless if the enemy has items that provide resistance to effects such as Sange and Kaya or Sange and Yasha. In such cases, the macro will not work.
The delay between performing the Astral and activating the Meteor Hammer was set up perfectly so that the enemy could not escape the camp. Keep this in mind when using a macro.
