Are there any archetypes that let you play a CG paladin?

[Alzrius]

A little while ago, one of my players asked me about potentially playing a paladin character with a Chaotic Good alignment (they didn't like what they felt was the restrictive nature of being Lawful Good). After we got the ubiquitous "just play a warpriest," "I don't want to play a warpriest!" back-and-forth out of the way, I told him I'd look to see if there was an option for a CG paladin archetype somewhere.

And so far, I've come up with nothing. I was already pretty sure that Paizo never made a CG paladin option (I've seen various third-hand assertions saying that was because James Jacobs wasn't a fan of the concept), but I'm surprised at how hard of a time I'm having finding one among third-party options. So far the only one I've seen is the free one on the Kobold Press website, and I'm not a fan of it (the aura of retribution feature potentially deals out more damage than a protected creature might take from an attack, and doesn't mention what type of damage it returns, which can be awkward if you're hit by an attack that does multiple types of damage at once, e.g. a +2 flaming dagger).

My other thought was to just turn the paladin of freedom, from 3.5's Unearthed Arcana, into an archetype (it pretty much is already), but there's a problem there too: the effect of the paladin of freedom's aura of resolve is something that the Pathfinder paladin gets anyway (i.e. aura of righteousness). The level they get it at is wildly different, but it's still enough to make it mechanically awkward. Plus "aura of resolve" is a name that the PF paladin already uses anyway.

So my question to the community is: have you come across a well-made paladin archetype that allows for a Chaotic Good alignment somewhere? If so, please let me know!

The closest thing to a chaotic good paladin I can think of would be a champion of the faith warpriest. It’s not exactly a paladin but it is pretty close. You don’t get full BAB but you do get better spells casting. You also get some bonus combat feats which can help boost your combat ability. You also get swift action casting of buffs so you are actually pretty good in combat.

As GM you could simply house rule the alignment restriction and create your own code of conduct. Then just file off the lawful spells and replace them with the chaotic spells on the list.

Pathfinder Second Edition has a CG version of the paladin right in the Core Rulebook: The liberator, officially called a "cause" of the champion class.

The closest official thing in PF might be the chaos knight. Don't get too excited because of the name, it still requires LG and is lower powered than the basic paladin. It builds some connection to the maelstrom though.

A more radical change is the vindictive bastard - which requires falling first. Despite the name, it can be of any alignment.

At the end, you might be best off with a homebrew archetype.

I published the Purifier paladin archetype in Path of the Wilds. It can be any good alignment and is focused on using holy fire to burn out evil. Not sure if that's something your player would be interested in (I don't mind posting it here if so; haven't added it to d20pfsrd yet).

As for porting the 3.5e Paladin of Freedom, I've given one of my players a basic conversion before:

Alternate Alignment: Paladins can become “paladins of freedom”, being Chaotic Good instead and focusing on freedom over law. In such a case, you gain the following modifications to the class.
Spells: Remove the following spells: protection from chaos (1st), arrow of law (2nd), protection from chaos (communal) (2nd), archon’s aura (3rd), discern lies (3rd), magic circle against chaos (3rd), dispel chaos (4th)
Spells: Add the following spells: protection from law (1st), shard of chaos (2nd), protection from law (communal) (2nd), magic circle against law (3rd), dispel law (4th), freedom of movement (4th)
Divine Bond (Su): Replace the ability to grant your weapon axiomatic with anarchic.
Code of Conduct: A paladin of freedom must be of chaotic good alignment and loses all class abilities if he ever willingly commits an evil act. Additionally, a paladin of freedom's code requires that he respect individual liberty, help those in need (provided they do not use the help for evil ends), and punish those who threaten or curtail personal liberty.
Associates: While he may adventure with characters of any good or neutral alignment, a paladin of freedom will never knowingly associate with evil characters (except on some sort of undercover mission), nor will he continue an association with someone who consistently offends his moral code. A paladin of freedom may accept only henchmen, followers, or cohorts who are chaotic good.

Vindictive Bastard is a great paladin archetype. It's lowkey still very good.

The Gray Paladin is another option that is Paizo. Can't be CG but you can be Neutral Good or Lawful Neutral.

For 3pp options, Spheres of Power/Might has 5 paladin archetypes who would qualify.
