Puny is easy to deal with if your Hero Sim does not have to fight for their profession. It is hard for the Monarch, Spy, Blacksmith and Knight to have this flaw, because they have Responsibilities involving fighting, hunting etc. For the Sims with the Jacoban Priest, Peteran Priest, Bard, Merchant, Physician or Wizard profession, it will not be much of a problem, because they do not have many activities that involve physical exertion.
