I used to be a minor, now I kill people
Okay, this makes use of the Sohei's Ki Frenzy, the Weapon Master's Increased Multiplier and Ki Crit, and the handy dandy x4 multiplier of the heavy pick.
Level: Sohei 1 / Ranger 1 / Fighter 4 / Weapon Master 10
Relevant Stats: Str 32 (18 base, +4 lvl, +6 belt, +2 tome, +2 Frenzy)

Strategy: Use i2wf and Ki Frenzy to get 6 attacks. When you have a 16-20/x5 weapon, this kills.
Okay: Attack +15 base, +11 str, +2 focus/sup. focus, +1 magic, total +29. with full attack, +23/+23/+23/+17/+17/+14. Damage for the 1st, 2nd, 4th, and 6th attacks is 1d6+1d6+1d6+11+1+2, for a total of 3d6+14. The other attacks are at 3d6+9. Critical of 20, feat extend range by 1, feat extend range by 1, ability extend range by 2 for 16-20. Multiplier of x4, ability increase by +1, x5. Now, here is the average damage including chance to miss due to opponent's AC, and chance of getting a critical. This is the average damage for one round of just swinging the pix against AC . . .

30: 370.95
33: 337.18
36: 303.41
39: 269.64
