Giant werebears are the most powerful of all lycanthropes.
They never are found in other then full-grown state.
Werebears alone are 50% likely to be in company with 1-6 brown bears.
They are able to summon 1-6 brown bears in 2-12 turns if any such creatures are within one mile of the werebear. <if uncommon, 20% chance? etc. etc.>
Their human form is typically large, hirsute, and of solitary temperament.
These creatures heal their wounds at three times the normal rate and are not subject to disease.
They can cure disease in another creature in 1-4 weeks if they so desire.

<note that bears will employ grappling attacks: DMG.73>

DMG: Werebears are the most powerful form of lycanthrope.
As with most lycanthropes, they will eventually flee to the woods.
Once a werebear engages in combat with a creature of an evil alignment it will fight until it or its opponent is dead.
Seventy-five percent of the time, if a monster with an evil alignment is encountered, the werebear will attack immediately.
