Kyn,
I have added comments and the spacing looks good. The only thing I had no real insight on was the levelable tag. You told me it was islevelable = true; so I added that on the Random slayer weapons. I did not know where to add it. This is something I will need help/guidance on since Evolution runs on a custom levelable system.
Also look at the Book Binder reward. I tested it and it works, the question is: Will it be allowed? If not I can change up that section and make a different reward.
