3. Immune to weaponry.
No matter with what you hit a werewolf, no weapon would cause any harm to the beast. Until it’s a silver bullet, or an object made out of silver perhaps. That is all we know according to the legends of all time. So if you ever come in contact with one try a silver bullet rather than a normal one. This is to be kept in mind if you have a strong believe in the existence of such a creature. You might be one of those in the United States who in the year 1999 got insurance policies just in case they turned into werewolves themselves. But many full moon-nights came and went by and none got claimed.
