So I love the Commander Zaheed sword, but I find it is too weak, so I wanted to modify it.
I changed some stuff around including abilities and changed the icon and animation file to OP infront of it since I named the sword OPzaheedsword. (Also where do I put the file itself?)

I will post the code of which I entered. Please check if this will work. I also will post a screenshot!
