Quickly Belladonna sent her blood dagger flying at him, trying to reach for her bottle in case that wouldn't work. She was scared that if she tried to use her magic - one that she had now discovered only worked on wood - she might pass out right here and that would just be plain stupid. A small cut would be enough for her blood dagger to drain him, she knew that.
Unfortunately, her blood dagger had no effect on him and it fell to the floor.
By Ignas, what?!
Well that was alright, she was already undoing the cap of her bottle.
But he grabbed her hands with those hands that had burnt the thieves and turned them into ashes.
Surprisingly, they had no effect on her either.
They both stared at each other in confusion.
