Not sure if this was intentional and i could not find another post about it(but im a noob when it comes to looking for older posts even with a search!)
But the effect mind and body, it overrides Hastening of Salik. Which is fine i suppose the haste on the wep is awesome as it is, but i found this out:
My chaotic gloves cast Augment, which wont override Hastening of Salik as its a less powerful spell, but it stacks with the donator effect.
So im not sure which one is the bug...
Hope this helps!
