Hello everyone, for some this may be a simple thing but... Does anyone know how to copy this skill Rain of Arrows v1.01
Because I tried but I got an error, which in the end my map almost does not open, since in this world of JASS it is something difficult for me (I get dizzy).

Your help is appreciated.

Are you copying the "Libs" and "Spell" folders over one by one and saving in between? What I did was make a new folder, drag the two folders into the new one, copy that into an empty map and save. That caused no problems.

But those 2 plus the ability did you copy?, Nothing else?
