Salvation Spell causes game to lag to the point that it is unresponsive and I have to force shut it down.

Salvation enchantment casting causes game to lag to the point that it is unresponsive and I have to force shut it down through task manager. I haven't had the chance to check if it only does it with my Mystic Sword though or any casting of salvation, but it does do it every time I cast it with my Mystic Sword.
