Quad Int to damage?

[ArchWein]

I was playing around with an Int to damage build (for lvl 10) and stumbled across something. Does this actually work?

MoMS Monk 2/Hexcrafter Magus 8
Hexcrafter lvl 4 hex is Prehensile Hair that says:

Effect: The witch can instantly cause her hair (or even her eyebrows) to grow up to 10 feet long or to shrink to its normal length, and can manipulate her hair as if it were a limb with a Strength score equal to her Intelligence score. Her hair has reach 10 feet, and she can use it as a secondary natural attack that deals 1d3 points of damage (1d2 for a Small witch). Her hair can manipulate objects (but not weapons) as dexterously as a human hand.

Feats include:

Dragon Style, Dragon Ferocity
Kirin Style, Kirin Strike
Feral Combat Training (Hair)
Combat Style Master

Starts combat in Kirin Style stance
First/Surprise round:
Action - grow hair
Swift - identify foe
Free - activate Dragon Style

If I understand it correctly the hair's Strength bonus is equal the Magus's Int, adds double that to damage on first attack (Dragon Ferocity) and can add twice Int as a swift (Kirin Strike)

Is this correect?

don't forget that the hair is a 'a secondary natural attack' and creatures that have only one natural attack (even if it's secondary) treat it as primary for bab and also get it's str at 1.5 time for damage.

so normal hair in a user with no other nat attacks would be (1d3 + 1.5x int bonus) for damage, before anything else.

from the monster universal rules , natural attacks section:

"If a creature has only one natural attack, it is always made using the creature’s full base attack bonus and adds 1-1/2 times the creature’s Strength bonus to damage rolls. "

So, base hair attack would be something like 1d3+7 damage. That's 5+(0.5*5 round down) = 7. Now, Dragon Ferocity will increase that to 1d3+10 (because it changes the 1.5 int to 2 times int).

Now! Kirin style adds damage to the attack as a swift action, after you hit, you can add damage equal to twice your int.

So ultimately I believe you're correct, but it's limited to once per round.

So while you do ultimately get to add your int modifier 4 times, it's through a very weird combination of abilities that can only be used once per round.

Generally though, you can't add the same ability modifier multiple times to something. However, I think the specifics of this case make it viable.

By raw, Dragon Style doesn't work with natural attacks, only unarmed strikes.

That's why they have Feral Combat Training
