Kensai (magus) and prescient defense

[Drowblade]

The Kensai recieves the canny defense ability, Int bonus to AC upto class level. Then one of the suggested arcana is prescient defense which grant the magus his/her Int bonus to AC against a particular enemy. Would this stack, does the magus then apply his/her Int bonus to AC twice against this one opponent?

Int is not a type of bonus, they are from diffeerent sources, so they stack. Note that canny defense just increases the dex bonus to ac, not ac directly
