Source War of Immortals
Many undead and supernatural predators have the ability to blend unseen among the general population, preying on mortals completely unaware of their presence. Vindicators are skilled warriors who use keen analytical talents and a smattering of divine magic to seek out such monstrous prey and pronounce judgment upon them. Evil religions, whose vindicators are more likely to be referred to as “inquisitors,” occasionally train their agents to seek out heretics within their own ranks, a fact that contributes heavily to the attitudes of fear and mistrust many vindicators find themselves faced with in the course of their duties.

Vindicator 1st

You have been specially trained to use guile and magic to reveal hidden threats. You must select Vindicator Dedication as your 2nd-level class feat.
Prerequisites: You must be a ranger.
Vindicator Adjustments: You must choose a deity to be a follower of, and you gain your deity's sanctification. You are trained in Religion instead of Nature.
You are trained in your deity's favored weapon.
If your deity's favored weapon is a simple weapon or unarmed attack with a damage die smaller than d6, you gain the Deadly Simplicity feat. If your deity's favored weapon is an advanced weapon, your proficiency with it is equal to your proficiency with martial weapons.
You must choose the vindication edge for your hunter's edge.
You learn warden spells as divine spells instead of primal spells, and your spellcasting attribute is Wisdom. When you gain domain spells via the Domain Initiate or Advanced Domain feats, they are warden spells for the purposes of all your vindicator feats and abilities.

Vindication Edge

Your specialized training gives you a unique edge that allows you to more effectively bring the tools of your faith to bear against the monsters that lurk in the night or hide among the faithful.
You gain a +1 status bonus to your spell attack rolls against your hunted prey, and they take a –1 status penalty to their saving throws against divine spells you cast. You gain the vindicator's mark warden spell.

Trackless Journey

Vindicators can choose to gain the benefits of this class feature in either urban or natural terrain, chosen at the time the class feature is gained.

Additional Feats

Source Player Core
Some archetypes include a list of “Additional Feats” that appear in other sources. The list includes each feat's level, which might be different than normal when gained from the archetype. You can take the feat as an archetype feat of that level, meaning it counts toward the number of feats required by the archetype's dedication feat. When selected this way, a feat that normally has a class's trait (such as the fighter trait) doesn't have that class trait.
