I am creating a character that should follow all the Pathfinder Society's rules. The character will not go to level 20 ( I think 14-16 will be his cap ).
Currently I have this overall picture:
Race: Dwarf (Darkvision; Weapon Familiarity; Defensive Training; Unstoppable; Relentless ; Industrious Urbanit; Rock Stepper)
Class: Inquisitor (Sanctified Slayer) 1
Stats: STR 16; DEX 12; CON 16; INT 8; WIS 16; CHA 8;
Traits: Fate's Favored. Magical Knack(Inquisitor)
Feats: Toughness(bonus from alternate racial trait), Lightning Reflexes (can still be changed, I simply didn't find anything fitting - everything I wanted required BAB +1)
A wandering dwarven inquisitor of Abadar, god of civilization, pursuing the profession of merchant and using Travel domain to strike fear into brigands who prey on the people using the roads. Using the racial trait Relentless, as well as an additional speed granted by Travel domain, I want to build a charger who tramples the opposition with a two-handed weapon. And the ones who remain standing shall quake in fear.
This inquisitor needs a quickest way to get Heavy Armor and martial weapons, so I am planning to dip Fighter on level 2. I have considered vanilla and all archetypes, and narrowed it down to Lore Warden, Siegebreaker and Unbreakable. Siegebreaker seems to give me the best overrun-centered options and doesn't trade out weapon or armor.
For an Inquisitor, I am trading out Judgements for some Slayer abilities with an archetypes. Getting a Sneak Attack for a heavily armored character is counter-intuitive, but I think it could work with just flanking. Gaining Greater Overrun would allow for free attacks versus enemies I overrun, ways to add sneak attack dies to that could be cool.
Gaining a couple of slayer talents could also be good, and I am considering Slowing Strike, grabbing a feat from Ranger's Two-Handed Weapon combat style(the 6th and 10th level ones become available), and Bleeding Attack or Surprise Attack from rogue talents. Just Weapon Training or Combat Trick could be gained there as well.
The Intimidate bonus from Stern Gaze on Inquisitor is nice and flavorful, so I was looking for ways to weaponize that as well through Dazzling Display or Bludgeoner + Enforcer + Intimidating Prowess. But intimidate goes after the tankiness in priority.
The order of taking the feats and slayer talents is of yet unclear (except Power Attack on 3, of course), and I think I can afford one more level of dip somewhere.
What should I do to optimize the effectiveness of this build at each level?
