Player Characters as Lycanthropes
A character who becomes a lycanthrope retains his or her statistics except as specified by lycanthrope type.
Character gains a strength of 15 if his or her score isn't already higher.
There are several references to non-transformed changes in the text around lycanthropy such as:
A werewolf is a savage predator. In its humanoid form a werewolf has heightened senses, a fiery temper, and a tendency to eat rare meat.
As well as in the description of the curse of lycanthropy on page 206
In its natural humanoid form, a creature cursed by lycanthropy appears as its normal self. Over time, however, many lycanthropes acquire features suggestive of their animal form.
