In the published module Curse of Strahd, Strahd (p. 240) can
turn into a wolf using his Shapechanger trait.
However, when he does this,
he loses access to his Unarmed Strike and Bite attacks and his Multiattack, since they are specified as "Vampire Form Only" or "Bat or Vampire Form Only".
However, it seems ridiculous to me that he would be unable to attack when doing so, I mean it's still
a wolf with fangs and claws.
My question, therefore, is this:
turns into a wolf,
what attacks does he have, what is his to-hit bonus, and how much damage does he deal?
