It was about a girl who could transform those who wronged her into wax figures. Then she’d summon a character (I believe it was a knight) to kill the wax figure with a sword.
I remember her doing that to avoid suffering from others mistreating her.
It was shown on TV in the 80s, but it could have been older than that.
It is not a group of people or the main character (the girl) fighting to survive. She was doing the killing. Also, not Wax Museum or House of Wax.
