RL-themed subclasses that feel real

[TheArcaneWeirdo]

3e Ravenloft products hand out setting-specific prestige classes like candy. It's one of the things that shock me most as a 5e homebrewer reading through older material - I was taught that an entire new class is a big deal that takes two years to make and has to be playtested a gazillion times.
Anyway, the thing I love about those classes - even if I can't escape the fear they'd turn out to be unbalanced or samey under scrutiny - is that they're things that would have a role in the setting. They fill a niche in the story. They could fit in to another setting, of course, but they feel tied.
5e Ravenloft subclasses are kinda '-class name- but spooky'. They aren't necessarily bad, but I can't escape the feeling they could be more inspired.

So this thread is where we drop ideas for 5e subclasses that are richer in flavour.

Here are some ideas I had:

[*]Paladin - Oath of Listening.
You've sworn to remember those who had been forgotten and listen to those who have been ignored. Your aura lets you and the people around you see into the ethereal, gives restless spirits a sense of calm, and... I need to figure it out.
Yes, it's a paladin medium. Not an obvious choice. But here me out - this isn't another dark and edgy paladin subverting the class. This is a goody-two-shoes paladin, who sees helping the undead find peace (whether by moving on to the afterlife or by accepting their current situation) as their holy duty. They might be a Mordentish follower of Ezra who got really hard into the 'even the legioneers of the night can be redeemed' thing, or a caliban who'd seen enough of humanity's prejudices to learn that anyone, regardless of creature type, deserves a chance to have their voice heard. Or, for a different take, a knight of The Eternal Order determined to appease the dead simply to protect the living from them.
But Oath of Listening isn't just about communicating with ghosts -
Your oath is to listen, to both the living and the dead. It encourages you to be interested in the characters around you - both PCs and NPCs. It pushes you to be the Face of the Party (Rather than hindering you at that like more lawful oaths). Maybe your support abilities are more mental than physical, allowing you to remove stress points or facilitate recovering from horror effects by helping your friends process their experiences.

[*]Ranger - Mist Crosser Conclave
For most people. the mists mark the border of the known world.
What's out there? Probably nothing good. Better stay inside.
Not for you, though.
You grew up wandering this foggy, confusing in-between space, and you understand it better than anyone.
Maybe you're half-vistani, and learned some tricks from your kin despite not having their full powers. Or you lost your way in the mists and had to survive there for weeks before finding your way into a domain - and found that you're no longer the same person who left, and feel more at home back in that dreadful place. Perhaps you nearly died from exhaustion after trying to cross a closed border, but was stabalized and returned to the land of the living with a new understanding of the mystique.
Abilities-wise, you have the mists as a favoured terrain, and you become even better at navigating them as you level up. Some fog related spells, of course, and maybe the ability to cause your enemy 'brain fog'? The capstone ability, of course, is the ability to exit and enter the demiplane of dread as you wish - but would you want to leave forever the place most of your abilities are tied to?
(This subclass would be very, very setting specific, but I have a feeling it would still be the least situational ranger build ever: The Mists might be unique to Ravenloft, but inside it, they're ever-present!)
While Mist Crossers seem uncanny and untrustworthy to the superstitious, they serve an important role in society as traders and explorers - especially in Islands of Terror who must cross the mists to have any connection to the wider world.

[*]Artificer - Dreadcrafter Specialist
AKA The subclass Van Richten would hate me for making.
It's centered around the idea of dread construct creators. You have a pet dread golem that gets stronger but also more autonomous and rebellious as you level up, until it inevitably turns into an independent NPC that might or might not be a sociopathic monster hellbent on killing you - depending on how well you educated it. Your spellcasting ability modifier isn't intelligence, but your negative wisdom modifier, to reflect how your power comes not from careful studying but from your being just delusional enough for reality to bend to your will. It's basically the subclass for players who come to the table to be abused by the DM, who love the angst of roleplaying a character's slow descent into madness and obssession - but also roleplaying what's basically a very weird familly relationship.
I have another topic about that one, but thought it deserves a mention.
