The vampire events refer to the base game characters as "brother", "sister", and "broken one" respectively.

Ironclad, for example, returns this: "Navigating an unlit street, you come across several hooded figures in the midst of some dark ritual. As you approach, they turn to you in eerie unison. The tallest among them bares fanged teeth and extends a long, pale hand towards you. NL ~\"Join~ ~us~ ~brother,~ ~and~ ~feel~ ~the~ ~warmth~ ~of~ ~the~ ~Spire.\"~"

@Override
public ArrayList<String> getStartingDeck() {}, public ArrayList<String> getStartingRelics() {}

Functions the same as before, but methods are no longer static.

@Override
public CharSelectInfo getLoadout() {}

Method is no longer static, and should call "this" instead of your class enum for its 8th parameter.

Inside main mod class: BaseMod.addCharacter has new parameters. Now needs an instance of the class you're adding, the card color enum, the file path to character button, file path to character portrait, and your custom class enum. Example:

BaseMod.addCharacter(
    new MyCustomCharacter(CardCrawlGame.playerName),
    MyCardColorEnum.CHARACTER_COLOR,
    PATH_TO_CHAR_BUTTON,
    PATH_TO_CHAR_PORTRAIT,
    MyCharacterEnum.CHARACTER_CLASS
);
