ok for the mana forgive me i mean your magic points. The werewolf get "no" special ability. his ability just become stronger.

You can deal 2x more damage (+100%), you can now feed on the animals/creatures, the totem of fear will work on highter creatures, you can summon up to 2 werewolf with a howl, you gain +100 health and +100 stamina, you recover twice as much health when feeding.

You may found all this information on this page Werewolf just under the skill tree.
