The Battle skill covers all forms of close-quarters armed combat using conventional weapons. For unarmed or unconventionally armed combat, see Brawl. For the ranged weapons counterpart, see Shoot.
Overcome: Since you don’t really use Battle outside of a conflict, it’s not often used to overcome obstacles. You might use it to display your battle prowess in a demonstration, or to participate in some kind of regulated bout or sport fighting, which would allow you to use this skill in a contest.
Create an Advantage: You’ll probably use Battle for most of the advantages you create in a physical conflict. Any number of special moves can be covered with advantages: a targeted strike to stun, a “dirty move,” disarming, and so on. You could even use Battle to assess another fighter’s style, spotting weaknesses in his or her form that you can exploit.
Attack: Battle is all about attacking. You make physical attacks using conventional melee weapons with Battle. Remember, this is for close-in work, so you have to be in the same zone as your opponent.
Defend: You use Battle to defend against any other attack or create an advantage attempt made with Battle or Brawl, as well as pretty much any action where violently interposing yourself could prevent it from happening. You can’t use this skill to defend against Shoot or ranged Brawl attacks unless you have a conventional shield.
