Using Werewolf Totem Perks
To use perks like being able to call on werewolves you will need the Totems of Hircine. You can get the Totems by doing quests for Aela the Huntress at the Companion's. There are 3 in total and each will allow you to activate a perk. You can only activate one of them at a time though. The Totem of The Hunt gives you the ability to see enemies in a similar way to that of Detect Life. The Totem of Brotherhood will allow you to summon either Ice Wolves or Werewolves depending on which perk you have. The Totem of Fear will increase your howl's ability to scare higher level creatures or characters. You only need to howl (RB) to use whichever perk corresponds with the totem you've selected.
