Hello guys, I have a 8th level Kensai-like PFS charactor Diviner 1/ Magus 7(Hexcrafter),worship in Desna. My tactic is to use a combo: Diviner's Prescience Ability + Emissary Familiar's Bit of Luck ability + high crit range obsidian kanata + Disposable Weapon UC feat, to draw a blade and auto-crit (80%+ chances) any foes with a optimized shocking grasp (in most of the cases, instant kill a boss without proper defensive ability). I use Headband of Favor's Fortune to prolong the duration of Bit of Luck to 2 rounds so I'm likely to made 2 consecutive critical shocking grasp in a single combat.
My tactic works well until now, but since each PFS scenario contains 4~5 encounter and my familiar only have 1/day bit of luck, if things becomes difficult and I need (my familiar) to use Bit of Luck before the BOSS fight, the final BOSS fight becomes hard to me. So I want to have a additional use of Bit of Luck (used by my Emissary familiar so it would not waste my action).
Here comes my solution and questions:
QUESTION 1:
My solution is to dip another level into Beast-bonded Witch and take a Improved Familiar (Lyrakien) with my 7 level magus, use the witch's Transfer Feats ability to grant the Lyrakien (Emissary Familiar archtype) Believer's Boon ACG Feat for 1 use of bit of luck per day. Since an emissary already have one use of bit of luck per day, could the familiar have two use of bit of luck with the Feat (one use from feat and one use from familiar archtype)?
QUESTION 2:(SOLVED)
In this case, I have a Lyrakien of master level 7 and a ordinary witch familiar with master level 1 . In PFS, only one "combattant animal" is allowed for each charactor. When I choose the Lyrakien as the combattant companion, can I get benefice from the 1-level familiar from my witch level? (like +4 initiative with a rabbit)
QUESTION 3:
When determine the Hex ability of a hexcrafter/witch, did those level stack? is the effect of a Fortune Hex from a hexcrafter 7/ witch 1 count as a 8-level witch?
Thanks for your answers!

Can you explain the math on this? I get ~51% chance.
Katana -> Crit range = 18-20
Improved Crit Katana -> Crit Range = 16-20 = 0.3 chance
Bit of luck -> Roll twice.
Chance of *not* critting = 0.7 * 0.7 = 0.49
Chance of critting = 1 - 0.49 = 0.51 = 51%
I mean, it is still nice and all...

Not crit = 0.7 * 0.7 * 0.7 = 0.343 = 34.3%
Crit = 1 - 0.343 = 0.657 = 65.7%
Still not quite 80%+, but getting there.

Ah, we both missed rolls.
Bit of luck is "any time you roll a d20" So it affects the to hit roll *and* the precience
Not a crit = 0.7 ^ 4 = 0.24
Crit = 76%

Since my wizard spells are almost useless, I use them to memorize lucky number, sure casting (V only) and the school slot for true strike (V only).
I often use wand of fallback strategy (when the party is not in danger) as pre-kickdoor-buff, or 2nd round buff.
Since bit of luck says that all the roll 20s can be rolled twice, and +1 keen obsidian katana made from arcane pool and do not need a crit confirm roll to autocrit on a crit threat, on each roll, I have a 30% chance to do crit damage.
In ideal situation:(I have fallback strategy on me)
Step 1 - Before my round, familiar use bit of luck on me.
Step 2 - At the beginning of my turn, I roll twice for the Prescience dice twice, and if their is a roll between 15-20 (51% chance), I'll use it as attack roll. If not (49% chance), I choose neither those result (or use the higher one to overcome SR),then...
Step 3 - Cast Shocking Grasp, move if necessary toward enemy and draw sword (I often cast at distance to avoid concentration checks), swift action to use arcane pool if necessary, then deliver as free action.
Step 4 - Roll attack roll twice and 51% chance to crit. 49% chance not crit, that means 49%x49%=24% chance not crit. If this 24% happens, then...
Step 5 - Use fallback strategy spell effect to reroll. This reroll can also be rolled twice, so 51% chance crit, 49%x24%= nearly 12% chance not crit. 88% chance crit. But for the 12%...
Step Bonus - Remember that we have a lucky number (always 1~14 if using a wand)? and we rolled 4 times in the round. 18% chance to have the lucky number and 51%x18%(x12%=1%) chance to crit.
In this case, the critical chance is about 89%. If GM allow multiple use sof prescience at "the begining of turn" (treat the begining of turn as a phase, not a time point), even higher.
*********************
And infact...
If the Prescience of Step 2 fails, I can just cast vanish or something and wait for another round. I have headband of fortune's favor, so bit of luck last 2 round. And only one optimized grasp is enough to beat most of enemy.
*********************
And...
Once in a PFS scenario boss fight, I rolled 1,1 on prescience, and 1,4 on attack roll. Not having fallback strategy effect nor touching luck number. Cursed by the Dice God.
*********************
And !!!!!
Can anybody tell me if I can get the 2nd use of bit of luck through Transfer Feats - Believer's Boon?
