During Hircine's Hunt, you'll fight many packs of very strong werewolves, unless you are one yourself. Silver weapons are extra effective as they do double physical damage and fire-based effects are less likely to be resisted.
As strong as they are individually, they become lethal in packs, so some form of crowd control is recommended ( Paralyze or Calm Humanoid).
Werewolves are humanoids that have great strength, speed and endurance.
