I'm trying to rebuild an old character I had. I'm looking for a Pathfinder 1E equivalent of the Outcast Champion from 3.5 Races Of Destiny. It is important that it has diplomacy, and Avenging Strike. I would assume a Paladin archetype might be closer to this but she is Neutral Good so I can only take fighter levels in that regard.
Any reason not to just use the Outcast Champion? Just take 8 levels in literally anything that has a use for Charisma, and put ranks in those two skills it requires.
Feats like Combat Reflexes, Bodyguard, In Harm's Way, Combat Patrol all make sense. Step Up. Follow Up. Step Up & Strike. Probably some Teamwork feats that fit, too.
Swashbuckler Arrow Champion gets Retaliation at level 1:
Retaliation (Ex) When a foe hits the arrow champion with an attack, she can spend 1 panache point to make a retaliatory attack of opportunity against that foe. If the triggering attack is a melee attack, she can retaliate with a melee attack using a light or one-handed piercing melee weapon, provided the creature is within her reach. If the triggering attack is a ranged attack, she can retaliate with a ranged attack using a bow, provided that the creature is within 30 feet of her. This deed’s cost cannot be reduced by any ability or effect that reduces the number of panache points a deed costs.
This deed replaces opportune parry and riposte.
Which isn't exactly what you are looking for, but it's a step in the right direction. I have drawn up a Bladed Brush reach build using Arrow Champion with a Glaive, so I know it can be done.
Anyways, I will keep looking, though...
