Concept- the fae aren’t weak to iron anymore
They used to be, but now goddamn everything is iron or an iron alloy, so they just got used to it. Like a vaccine but for magic. Now, when your monster hunters meet them and pull out a cold iron horseshoe, the fairies just grab it out their hands and beat them up with it.
It turns out the most useful member of your team is the puppy who is someone’s familiar that has been carrying around a plastic chew toy for the last six months and all fae after the party see this little dog lolloping toward them and go, “ahh fuck this, he’s still got the spicy rubber metal.”
