I have to agree with Legolas and VillainX and many many many many many others. If the game can be designed that there is a physical weapon (sword) and a magical weapon (staff) and only mages can equip staff and all other characters can only equip a sword. Then the sanctification can be designed to only give magic attack to mages and physical attack only to every other class.

Another option would be to just remove physical,skill and magical attack as a sanctification bonus completely
Theres plenty of other random bonuses that can be added and all the rest make every character stronger
