little lost on damage multipliers, please help..

[morkendi]

I am playing a psychic warrior. At 9th lvl. I have free la of 2. I took halfgiant and feral. My feats are as follows with account for 2 flaws. Strength is 28 with all magic items. Weapon is large great axe +3. Feral gives me pounce.

Power attack
Combat reflexes
Cleave
Imp bull rush
Leep attack
Imp sunder
Shock trooper
Great cleave
Combat brute
Link power

Trying to get a formula i can write down on paper. I think i am doing it wrong.
3d6 +16 base before expansion. +12 if i put 6 in on power attack. ×3 for leap attack? Combat brute can make it ×6 instead?

[Tohsaka Rin]

Leap Attack isn't a multiplier, per se. According to errata, it just doubles Power Attack.

Which would've been great to know years ago, as I would've killed Kurtulmak. Dammit.

[morkendi]

So a 6 power attack with 2handed weapon is doubled for 24 and combat brute wich says ×3 would ad 36 more for total of +60 to die roll and bonuses?

[Tohsaka Rin]

No.

6 Power Attack
2handed weapon (x2)
Combat Brute (changes x2 to x3 instead)

Total 18

THEN Leap Attack doubles.

Total 36

And with pounce from feral template i get full attack and with shock trooper, i can assign the -6 to ac instead right?

Also, i normaly charge and full attack. Then manifest hustle to back off and let things come to me for 3 AoO. Do i get the bonus damage for the AoOs?

Also any suggestions for future feats? I know the next will be expand knowledge for psychic reformation. I see extend power, but no persist. I will probably go slayer if I dont see any feats to increase damage.
