Actually, I have made this work manually (without UI, and set variables by cmd) after researching the main.map released last year.
This is just a gift from Webzen, they left it in their main. You also can see it directly in the GOD's release main source.
The core of all magics is EditObject() function and its depending var EditFlag.
I've just made a quick port to Season 16. Maybe I'll soon release the SOURCE after testing and fixing bugs.
Anyway, I think MuEditor is easier to use + much better than an in-game editor. So just for fun ^.^
