Given my knowledge of folklore, a witch/ninja/vampire/werewolf would have the powers of:

Animal transformation
Hypnosis
Wallcrawling
Telepathy
Rejuvination through blood consumption
Shadow movement
Animal control
Walking through walls
Flight
Enchanting
Cursing
Immortality
Invisibility
Potion making
Walking on water
Immunity to fire
Smoke transformation
Enhancement by moonlight
Zombie creation
Demon summoning
Body possession
Superhuman strength
Passing on powers by letting them drink your blood
Manipulation of all five elements
Accelerated healing
Flying
Teleportation
Healing others without aid
And turning people into frogs

But that’s it, you don’t want her to be too overpowered.
