When making my New Sacred Fist Warpriest I had a few issues that i needed some clarification on.
First was that taking my starting feats I was unable to select Pummeling Style, despite having the monk ability Flurry of Blows and Improved Unarmed Strike.
From my understanding on the official rules this is all that is required http://paizo.com/pathfinderRPG/prd/advancedClassGuide/feats.html#pummeling-style
The second issue was that in the character sheet portion the Unarmed strike damage was not scaling as a monks does despite using the same formula
Unarmed Strike: At 1st level, a sacred fist gains Improved Unarmed Strike as a bonus feat. He uses his warpriest level as his monk level for determining the amount of damage dealt with an unarmed strike. This ability replaces focus weapon.
So not sure if these are bugs or what not. I tested by making a level 1 monk and it can take pummeling style at level 1, so not sure why sacred fist cannot.
I have made the character in the latest Version of pcgen (6.06.00 RC1)
