If there are people throwing around curses, there should be people who can get rid of them. Or maybe charms that can counter them, I don't know. It seems like an actual good luck charm should be able to counter bad luck if we're assuming all of these things actually work.

[Davesprite is, at this point, ignoring the occasional bear paws at his tail in favour of considering this idea. It'd be pretty shit if they had working curses here, but not working charms.]
