Vampire and Occult Suggestions

I enjoy the challenge of a Sim choosing to become an occult or becoming one by accident or misadventure. It becomes part of my games lore.

So I have 2 Spellcasters as examples, one I forgot to create as a Spellcaster so she consumed motes and sought the sages to become a Spellcaster before becoming obsessed with power and dark magic, like the motes have corrupted her. My other Spellcaster, Aurora is a wiccan who was created as a Spellcaster and only carries out good magic and never messes about with motes or duelling. She has birds, rabbits and foxes on her lot and sells flowers and homemade remedies and preserves. She doesn't use a wand or a broom or dark magic familiars.

It was quite a fun aspect to the pack when Pandora ate a bad mote, turned to the dark side and started duelling and hexing everyone from the postman to the shop keeper.

It was the same with mermaids, like what happens if I eat this fruit? Yikes...where did this shiny blue tail come from!? Quick, someone chuck me in a paddling pool!

For me it makes my characters a bit more interesting.

I can't speak to Vampires or Werewolves as I'm too squeamish to add those packs. But I can certainly see how that could also be entertaining getting suddenly transformed.
