I tried this mod tonight but when I cast the Slowfall spell, nothing seems to happen. My character raises his arm like he's casting, but there is no effect and I get a sound like I don't have enough magicka (but I do). I still gain Alteration skill experience though, but the slowfall effect doesn't work.
Anyone have any experience with this? Without this spell, I don't even need this mod, since Supreme Magicka adds Jump and Levitate.
Thanks.
