Frontline challenges are daily challenges found in the Duty Roulette which pit teams of players fighting under the banner of each Grand Company in training exercises that test the strategic planning and combat prowess of each participant.
Frontline is a PvP challenge in which players are randomly assigned to a Grand Company and battle for territorial dominance. Each team consists of 24 players in an Alliance, allowing for 72 total combatants on a single map. Players must not only work hard as individuals, but must also work together as a team in order to prevail.
Each alliance is divided into three full parties of eight players, and each frontline match lats for a maximum of 20 minutes.
If a player is defeated, they will be returned to the landing platform of their Grand Company, and will be allowed to rejoin the fight after 5 seconds. When leaving their landing, players will temporarily receive the Invulnerable buff, preventing any and all damage for a set amount of time, or until moving far enough away from their landing.
Each player is allowed to ride any mount during Frontline campaigns. However, if a player takes a certain amount of damage, they will receive the Limp debuff, drastically slowing their movement.
KDA (Knockout, Defeat, Assist) is the scoring system used in Frontline matches. If a player deals the finishing blow, they receive a Knockout, and 10 points to their Battle High gauge. If they themselves are defeated, they receive a Defeat, and lose half their Battle High Gauge. If they help knock down an opponent, they receive an Assist, and gain 5 points to their Battle High Gauge.
As players gain Knockouts or Assists, their Battle High gauge slowly fills. For every 20 points in the gauge, players gain a stack of Battle High, increasing their damage dealt and HP restored via healing actions. The maximum stack a player can have is Battle High V, greatly increasing how much damage they deal and how much they heal. For every Defeat, a player loses half their Battle High gauge.
