Okay, so after reading over this thread for the last couple of days, I have come up with a slightly different build. I wouldn't say that he is better, but he has a couple of amusing mechanics.
Cotton Kleer Warpriest of Cayden Calien
Half-orc Oracle 1/Warpriest 3/Weapon Master Fighter 7
Str 16+2(racial)
Dex 15+2(level 4 and 8)
Con 12
Int 10
Wis 14
Cha 7
Oracle 1- Throw Anything, Stone Mystery(Rock Thrower), Tongues Curse
Warpriest 1- Focus Weapon(Rock)
Warpriest 2- Point Blank Shot
Warpriest 3- Precise Shot, Rapid Shot
Fighter 1- Weapon Specialization(Rock), QuickDraw
Fighter 2- Deadly Aim
Fighter 3- Snap Shot
Fighter 4- Combat Reflexes
Fighter 5- Improved Critical(Rock)
Fighter 6- Improved Snap Shot
Fighter 7- Toughness or Farshot
Traits- Fate's Favored and Reactionary
Blessings- Liberation, Travel, or Good
Alternate Racial Trait- Sacred Tattoo
I took Throw Anything to avoid having to deal with proficiency issues, since it negates them for anything that you could possibly want to throw.
The Warpriest levels allow for swift action casting of Divine Favor a few times a day and a free weapon focus and a bonus feat.
Then obviously fighter the rest of the way. I really like this build at higher levels for the Snap Shot feats, allowing me to throw rocks at people provoking AOOs anywhere within 20' at level 10. I am able to qualify for these feats with the Warpriest caveat that allow him to use his level as his BaB when qualifying for feats.
