She's a Paladin, I'm pretty sure of it. "Paladin of Zariel", but probably Oathbreaker now technically, but I suspect Vengeance is what she's going to be. Saying that, if she was a Paladin, that means she his lying, as nobody become a Paladin unwillingly
How does an Oathbreaker Paladin function in dialogue? I'd imagine a regular Paladin has to say things in line with their Oath but once you break it are you just a regular character in terms of mechanics?
The only way to leave Oathbreaking is by atoning (which means showing you are repentant and doing quest to regain favor).
If a Paladin break his Oath, he should become an Oathbreaker, but I'm not sure if that's going to be in the game. Devotion is easy to track via dialogues, but Vengeance is not.
The problem with Karlach is that Oathbreaker doesn't really fit what we know of her mechanically. Vengeance would fit better.
