Recently i noticed something really weird.
When i change my mace to a fist or one hand axe it increase my spell hit chance by 2%.
It seems to affect only the spell hit chance and seems to work with all specs.

Is this a bug or some ability that i am not aware of?

P.S. im a orc so it might has to do with the orc racial. However the orc racial should grant only +1% expertice when using axe and fist...
