Defence against Werewolves?
I'm in the middle of writing a fan-fic where Remus becomes a werewolf. He didn't use the wolfsbane potion at this time so he's feral and aggresive to humans.
My question is, What spells could/would be used against a werewolf? We don't want to kill Remus because he's pretty awesome but what spells could be used? I know there's Stupefy and Immobulus but is there anything specifically for Werewolves?
I'd be extremely grateful for any ideas.
P:S also the wizard casting the spells is an adult so they should have a wide armoury of spells.
