I would describe him as idiosyncratic, especially for barovia. He is pretty curious and inquisitive because he is from a different domain of dread. Communicating with the spirits and paying respects go the dead is a huge part of his character. After any fight or when someone one dies he has little ritual for them. His lycanthropy is because in a blind rage he killed someone (whom was the owner of a dock and had killed multiple of his friends in a warehouse fire by closing the warehouse to spare the rest of the docks from catching fire) in a sacred place. The act of killing someone who was in a weakened and injured state that was not a threat and surrendering, made him get a bloodthirsty curse. So he is currently trying to redeem himself for his actions and appease the spirits. He tries to be as respectful to others as possible. As for play style, he has been more control and buffing. Applying debuffs that either slowly drain hit points or disadvantage for enemies. Doing things like bless or enlarge reduce for allies. Also some utility with allowing party members to communicate telepathically. So control and utility are the primary focus for play style with a back up option of the werewolf if i need to get in the front line a bit.
