Shadow Armor gets you Mage Armor at-will.
I’m still considering replacing one of the classes with rogue or just adding rogue (one level at level one, and eventually 3-5 total rogue levels).
The build needs divine magic (or magic I can flavor that way easily), radiant damage, efficacy while using weapons that aren’t immediately recognizable as weapons (ie daggers, preferably dual wielding), and using supernatural abilities and magic to accomplish what a rogue/ranger would do largely by physical skill and prowess.
And of course, be made a using classes I actually like to play lol.
I’d love to make it as a monk, but I see no way to do it without a custom monk subclass or a houserule to use wisdom for the Paladin, or maybe a more divine Ranger subclass. And even with one of those, I’d need either great stat rolls or to ignore the multiclass stat requirements to do monk-paladin.
And honestly Paladin provides so much of what makes a good “agent of divine wrath against supernatural evil” that it’s hard to ignore.
Anyway, the current build is probably ditching GFB but keeping true strike (my dm will let me use Dex instead of cha for that so it’s a good magic longbow attack option). I’ll keep Pact of the Blade because making one weapon deal radiant damage is part of the basic concept and it’s an easy way to do that.
So Warlock, pact of the Blade, Armor of Shadows, and I’ll choose a utility invocation like pact of the tome or maybe lessons of the ancients, or part of the chain with a sphinx (flavored as a small coatl guy) familiar.
Paladin, TWF, dagger and possibly short sword mastery even though I intend to use Shadowblade a decent amount so a second melee mastery isn’t going to come up a ton. Might use Shortbow rather than longbow and grab mastery with that.
Spells: divine favor, wrathful smite, compelled duel, armor of Agythis, Shadowblade (homebrewed to radiant damage), and all the Vengeance Paladin and Archfey Warlock spells.
Skills: Stealth, Investigation, Religion, deception, insight, athletics, persuasion, and a musical instrument just because. (Skilled, changeling, warlock, paladin).
Feats: Not actually that impressed by dual wielder, but gonna grab skill expert for expertise in Stealth and to grab maybe sleight of hand, later I’ll grab speedy or skulker.
I’ll make another post later with how I’d do this using monk and ranger and maybe even explore monk-paladin in spite of the obstacles there.
