A sweet one-night D&D adventure in which 1st-level characters wake up naked in Castle Ravenloft

Vampires aren’t real

If a player receives a spell from a dark gift in Curse of Strahd and survives the saving throw to become evil…

In two weeks I begin running Curse of Strahd, any words of advice?

CoS the Holy Symbol of Ravenkind requires attunement, would a Celestial Warlock or Divine Soul Sorcerer would fit?
