Field Attacks (フィールドアタック,Fiirudo Atakku?) is a new game function to the Trails Series. Starting in Zero no Kiseki, they were called Attack Encounters (アタックエンカウント,Atakku Enkaunto?). It allows your lead character in your party to attack. If you manage to hit enemies from behind, the attack will faint them long enough to engage in battle and giving your party the full advantage (noticed by the circling bird icon in cartoons).
Your party can always takes action first depending how high each character's statuses are (LVL, high speed, etc.)
If the Enemy Advantage, this first point becomes the opposite with the enemies surrounding your party in a circle.
All attacks become critical if possible
The enemies are considered "small-fry" if the level between your party and enemies becomes a huge difference. Any field attack attempted is capable of destroying them, thus skipping battle while collecting sepith.
