Martial arts
The Martial Arts skill is a new skill introduced in The Sims 3 World Adventures. The Athletic skill is not the only factor that determines a Sims chance to be victorious in a fight, as the training a Sim receives in martial arts is a new factor and seems to play a major role in fights. The skill level also determines how likely a Sim is of defeating a mummy in a fight, as a low level may cause a Sim to be afflicted with the mummy's curse, that will cause the death of the Sim after a set time.
