I'm writing a story in which main character is a necromancer and I need a weakness for her. I was thinking that the necromancer powers took over and make her evil but I don't know, ideas? Btw necromancers can raise people from the dead.

Ooo interesting question!

I like John's answer, very clever. Something like this would go down well.

Introducing a "fatal flaw" to your character always adds a bit more depth.

Maybe another suggestion would be "for every life that the necromancer restores, it must extinguish another in order to maintain the cosmic parity between the world of the living and that of the dead..."

This story sounds very interesting! , maybe everytime she revives someone , she gets flashbacks of how the person has died , and this sometimes really scares her because maybe she finds a girl who was murdered and she revives her and goes through how the girl has died and she puts the pieces together , or she may have a limited revival number and everytime she revives someone a number imprinted on her hand goes down , and then she will die , but then she is in a world of the plague or something like the apocalypse and many of her friends fall really ill and she tries to save them but she knows it is limited ? , these are my ideas but I love the sound of your idea :)

Water Or A Poison.

Really cool premise, if not that every time she revives someone, someone else has to die then maybe ...maybe she feels how they died, the physical pain.
