So it has now been three years since I last logged onto thehelper.net.
At the time I was using the wc3 world editor.
I'm just wondering how different the SC2 map editor is compared to the wc3 one and how hard it will be for me to adapt (extremely rusty)
If this is for all spells this will not be easy. You will need a system that detects damage from your spells. Therefore every single spell you make will have to be triggered to this system and if you already have spells you'll have to redo all of them.
And the above posters won't work.
