Use this action to perform your characters' favoured attack. For example, Jack is equipped with a long knife, so his preferred combat is with the knife. Harriet is trained in hand-to-hand combat and attacks with her fists. Horatio, uses his pistol. Charlotte throws her explosive mixtures. And Enrico uses his garrote. If you are using a weapon with which you are not familiar, the Narrator should apply a penalty to your combat effectiveness.
Combat is also used to dodge incoming attacks. Depending on who is attacking you, there will be a different threshold to dodge the attack. The Narrator has this information. The Players will need to figure it out from context.
