I have created a small number of new flaws to use in your chronicles. You will have to determine their value, however, as I often find that the points rewarded to players for specific flaws really should be tailored to the style of the individual chronicle and troupe.

Uktena Flaw
Bane Guard---the Uktena has been stuck watching over one of the tribes
various trapped Banes.  This will take up a good portion of the garou's
time, unless he can arrange some sort of shared responsibility he may
have virtually no time.

Euthanatos flaw
Stuck in the Wheel--the Euthanatos has been marked by her own tradition
as unable to progress very far this life.  She is being carefully watched for the moment when the Freedom Razors determine that her karmic growth potential has come to a stop and then, snikkkkkttt.  Ah well, at least she can look forward to trying to kickstart the wheel.

Uktena flaw
Fear of Crowds (If you really like, you could look up the clinical term)
The Uktena has grown too used to being a lone wolf in the desert, and
has trouble working with a pack.  Subtract two from all social die pools
in any group situation.  The uktena has no trouble dealing with
individuals, however, and often enjoys short term company.

Euthanatos flaw
The Perfect Death--the Euthanatos can only ritually administer the Good
Death in a particular way, due to religious or personal beliefs and past
life karma.  Any other death he administers will somehow not benefit the
soul and surely mark him for extermination by his own tradition.
Examples might include Euthanatos who can only kill via sacrificial
dagger, or only via barehanded attack.
