Well, the Powerhouse seems to have made a big leap between the Intermediate and Advanced round.
Some of the player's long term investments finally paid off in a class that really benefits from impressive physical scores.
Thanks to the Occupation choice of mobster, Endurance Training was an improved feat for this character, granting a +2 Con (and the player could select the feat even though it's a Tank feat).
The player backed this up by selecting Strength Training as a normal feat for +1 Str, then using his free ability increase at 8th level to raise his Str to 18.
Sneaky and slick.
And the character is still a terror at close range.
