Experimental Advanced Item Generator
My fork of @Versss Rotmg Muti-Tool, this program will do all the hard work for in adding custom items to server clients.
All you have to do is give it a input swf, and a 8x8px sprite of the item to add.

Note:
This is literally 100% untested, and made at 5am yesterday. Please don't look at my awful coding. That being said, this /should/ theoretically work. I just haven't actually tested it by playing with a modified client, but it does edit the sprites and everything.
