Ok,with the Knowledge is Power feat, I think my Knowledge-based fighter archetype is ready to roll.

 

Knowledgeable Fighter

You’ve studied in class, listened to the bards, or learned on your own, but in either case, you see the true power of knowledge and how you can hurt others with it.

 

Knowledgeable Fighter (EX)

Gain the Knowledge is Power feat (https://throatpunchgames.com/2014/11/01/daily-punch-10-28-14-knowledge-is-power-fighter-archetype-for-pathfinder/) at first level as your bonus feat.  You must take this as your bonus feat.  Also, all knowledge skills are now class skills for you.  Replaces Bonus 1st Level Feat

 

On the Job Training (EX)

Increase the number of skill ranks you gain each level by 1.  Chose an additional knowledge skill.  You are now trained in that skill.  This replaces Bravery.  Gain this ability again whenever you would have an increase in the bravery skill and cumulative.

 

Lessons Learned (EX)

Choose either Armor Training or Weapon Training.  When you would gain a this ability, gain a +1 to all knowledge skills you are trained in instead.  This replaces weapon training or armor training. Gain this ability again whenever you would have an increase in the ability you choose to replace.  This ability is cumulative.

 

Knowledge Mastery (EX)

When you would gain either the Weapon Mastery or Armor Mastery, based on the choice you made for your Lessons Learned class feature, you instead gain this feature.  When you would gain a bonus from your Knowledge is Power feat to either attack, defense, or saves, now gain a bonus to attack, defense, and saves equal to the total bonus before the bonus would split instead.  This replaces Weapon Mastery or Armor Mastery.
