Creating a map with the Tear of Ashi.

just like in the thread about creating the tear, find the message from user KioM, where an excellent screenshot is attached. In the editor, right-click on objectives -----> create a new task, and then enter Objective_kind_Defeat_all (highlighted in red in the screenshot).
Then, change instant victory to true (highlighted in green). Now, theoretically, you can win the map in two ways: by finding the tear or by killing everyone.
