When the medieval society in question just pulls out a magic ballista and 360 head shots the supernatural threat
Maybe Euron imbued them with magic from the Drowned God, the arms on them did look like tentacles.
But in all seriousness, I understand why the show writers did that, because it's pretty obvious who's going to win the fight for King's Landing if one side has a pair of invincible flying death monsters (even if actually using them on a city full of innocent people would be a horrifically barbaric act.) At this point, I kinda just want to get the last two episodes done and over so I can see if Bron finally gets his castle
There would probably be ways to handle that if they were clever or they could work with how horrifically evil it is to turn it into a phyrric victory or something. I dunno. I don't watch the show.
They've already been working that angle before it's even happened, there's even been a few scenes to show us the horror of death by dragonfire ---
