I of course don't know MonkeyBomb's take on this, but I would personally say the it would take a substantial "Wound" to actually kill a Werewolf. Beating the crap out of it with a silver Mace would only wound it unless it is a beating that we would normally associate with being lethal.
Nothing "Mythical" or "Mystical" would do much more than annoy it.
That is where the modern Hollywood comes in as they introduced the silver for werewolves
In at least one movie a werewolf is killed bring being struck in the head by a silver handled walking stick
In many traditions including some Early Christian groups silver was a ward against evil as was pure iron (example using iron nails to close a coffin)
