Human Fighter, Level 3 (2h greatsword)
If you're rolling and get an 18, use your +2(human) on that and make it STR.

20 STR = +5 mod

You will have 5 feats at level 3.

Weapon Focus
Power Attack
Furious Focus
Cleave
Quick Draw

Furious focus will cancel out your Power Attack penalties to hit at low levels, so you can always use max Power Attack AND Cleave right afterwards because you only have one attack. Unfortunately the Cleave will receive the negative to hit from your Power Attack because Furious Focus only works on your first attack.

To hit:
+5 STR
+3 Level
+1 Weapon Focus
Total = +9

Use Power Attack at a -9. While using a 2h weapon like a Greatsword, you will get +27 Damage.

2d6(Greatsword) averages at 7 damage.

7(2d6 average) + 7(STR Mod using 2 hands on a 2h weapon) + 27(Power Attack maxed)
Total = 41 Damage on average.

Now, the Furious Focus will cancel out your -9 to hit from Power Attack.

So in all, at level 3, you have a single attack at +9 to hit and an average damage of 41. Then a Cleave.

I'm not 100% sure on this, but I see nothing in the books telling me it wouldn't work. Please let me know if you find anything contradicting this.
