Echoes of War are challenges that will open after completing specific Trailblaze or Trailblaze Continuance Missions. During these challenges, the player will relive the experience of fighting Bosses encountered in the story.
Echoes of War are similar to Bosses, having powerful attacks and two or three phases.
Players who defeat the Echo of War are rewarded generously, with the main reward being a unique Trace Material that is required to unlock Bonus Abilities and upgrade level 8 and higher Traces. Other rewards include Relics (of which two sets, most commonly Musketeer of Wild Wheat or Thief of Shooting Meteor), Lucent Afterglow and various free 4-star, easily obtainable Light Cones (which can also be bought with Lucent Afterglow) and Credits.
Players can complete Echoes of War three times a week, and the same Echo of War can be challenged multiple times. 
Trailblaze Power ×30 is required to start an Echo of War and obtain its rewards. It is possible to start an Echo of War after all three challenges per week were exhausted, but the player will not receive rewards. Reward availability is refreshed upon Weekly Reset. Certain Achievements require accomplishment of certain objectives in Echoes of War, but they do not require Echo of War rewards to be available.
