Wolf Form - one or two damage?
It doesn't matter.

The section in the first page of the Rules Reference from FFG itself, titled Golden Rules says


  This Rules Reference is the definitive source of rules 
  information. If something in the Rules Reference 
  contradicts the Learn to Play booklet, this document takes 
  precedence.
  
  If the rules text of a card or game component contradicts 
  information from the Rules Reference, the component-
  specific rules text takes precedence.


Thus a hierarchy of correctness is established, so that the "most correct" statement is whatever the card itself says.

The card says two damage. Dracula takes two damage. End of story.
