It works on white walkers, so why not Dracula’s minions?
Unfortunately, the Redditor who picked up on this easter egg didn’t have any lengthy and heavily cited arguments for either side.
One has to wonder, if Trevor Belmont were to use Longclaw, would the Valyrian steel cut through hell’s demons without putting salt on the blade?
Then again, Belmont is more of a whip and other-sword kind of guy, so maybe he’s better served with his own consecrated weapons than any rare metals of Valyria.
