Monk (Unchained) and Psychic with Self Perfection Discipline

[Thatcher Iliff]

If I multi-class in both Monk (Unchained) and Psychic (Taking the self perfection discipline), do I get to add my wisdom bonus to AC twice? Hero Lab calculates it twice, but I'm not quite sure what the ruling on that would be. Would they stack because they are from two different classes and because they are two different abilities? One adds additional AC as you level, while the other only adds the wisdom. I would appreciate official rules text citation on why this would or would not be true. Thanks!

When unarmored and unencumbered, the monk adds his Wisdom bonus (if any) to his AC and CMD. In addition, a monk gains a +1 bonus to AC and CMD at 4th level. This bonus increases by 1 for every four monk levels thereafter, up to a maximum of +5 at 20th level.

These bonuses to AC apply even against touch attacks or when the monk is flat-footed. He loses these bonuses when he is immobilized or helpless, when he wears any armor, when he carries a shield, or when he carries a medium or heavy load.

I had a guy in a recent game play this combo and at lvl 2 with mage armor and reduce person was effectively AC:30

Is this legal?

[Chess Pwn]

no, you can't have wis to ac twice. there's a FAQ for that.

Do you have a link? The argument made was that as an unassigned buff type (divine, moral, etc) that they stack.

This was tried with the monk/sacred fist stacking and why they are careful to not apply a specific bonus unless they want it to stack. For example look at a Nature Oracle with Nature's Whisper (Cha instead of Dex to AC) and Osyluth's Guile (adds Cha mod to AC as a dodge bonus) which is one example of stacking Cha to AC twice. Unless the language includes some type of bonus, the bonuses won't stack.

Another one I have seen is White Haired Witch (Int to grapple) plus Magus Arcane Accuracy (Insight bonus to hit equal to your Int mod)

That actually works. The faq stops untyped ability scores from stacking. An insight bonus would stack.

I know, I was saying that the one example quoted doesn't work, here are some that do.
