[ Shaking himself out a little, Derek tries to push down his anger towards Lycaon and his wolves. They're predators, but they don't have to be killers. They should be using their abilities to protect those that need it.

He looks at Scott, takes in his expression, before inclining his head in a nod. ]

Silver is the only metal that can actively harm a werewolf. Otherwise we'll heal, or outright resist injury. I don't know about Stygian Iron, but I haven't exactly been willing to try it out personally and we don't really have a surplus of weapons lying around. If you can't get your hands on anything with silver, then you're going to need to coat your weapons in some kind of poison-- wolfsbane, especially, but mistletoe and wolf lichen are also effective. Those are your top three choices.
