It doesn't work. The only thing that works is that the spell casts when the casting time is, the animation goes off, and the hit from magic/physical attacks causing the animation works properly as well. I don't care what someone says who is rank twenty minus. It doesn't work. People who claim it has a minimal effect need to remove all of their mnd and use shell and see what it "does" and then let it wear off and see what it does. The only thing they see is the calculation being random, which it is for a few varying degrees.
