Very well documented, but I got a question. What exactly do you change if you want the damage modified? In my case, I want each sin to deal 50 instead of 100.
5/5, just as an FYI.
*EDIT*
Nevermind, I guess I'm just blind. Problem solved. ;P
*EDIT 2*
Only complaint that I have is that GUI spells are a beotch to import as there's ALWAYS something that gets changed when importing to your own map. You should switch over to vJASS. >;D
