What are some spell ideas that would fit this?

At her prime point in her life she becomes a dark, arrogant and sadistic woman.
She lives in more modern world but lives in a mansion and loves dressing in Victorian clothing.
She carries a hollowed out staff with a sword and has both a modern age high tech pistol and flint lock.

She is immortal through dark ritualistic means and I'm wanting possibly a spell or 2 but I want something that's dark, cool, and not TOO crazy.

Any ideas?

Oh, she also has a pet crow and wears a crow mask.
