Rebuild Stream is a build that uses Gale Thrust as its special attack, with the core strategy being to increase the accumulation speed of Courage, thus allowing for more frequent use of Gale Thrust. How good the Star Trace Resonance Rebuild Stream is isn't entirely clear just from this point, because while focusing on the core, players need to maintain a high-level sharpness state by triggering the consumption of Courage to refresh skill cooldowns, thereby increasing the frequency of Spiral Thrust.

In terms of skill combinations, essential skills for the Rebuild Stream include Wind Grace, which accelerates Courage accumulation and boosts strength, and Spiral Thrust, which enhances core damage ability. Spiral Thrust has a higher priority than Gale Thrust and deals more damage. Additionally, it requires skills like Break Pursuit, which enhances large-area damage and Courage accumulation, where more enemies hit result in more Courage gained, and Courage Wind Ring, which provides sustained damage and off-hand skill effects. Be mindful of maintaining Courage and try to extend the duration of Courage Wind Ring.
For equipment choices in the Rebuild Stream, you can choose to enhance survivability with Wind Protection, which is better against enemies with high attack frequency. The main attributes for cultivating this build include base attributes such as Strength, which increases the physical attack and defense power of Azure Knight, and advanced attributes like Haste to boost attack speed and casting speed, as well as Mastery to enhance the damage increase effect provided by each layer of Sharpness. For recommended Resonance Power combinations, you can choose ultimate skills that boost Haste and Mastery within a short time, such as Lion's Pounce and Ultimate Skills, Electromagnetic Bomb. If there are other needs, choose based on the characteristics of each Resonance Power.

For recommended specialized skills, it is strongly suggested to carry Wind Grace, which has the effect of recovering Courage and increasing damage. Spiral Thrust is the core skill that consumes Courage for output, while Break Pursuit recovers Courage by attacking multiple enemies, and Courage Wind Ring continuously consumes Courage to cause area damage. Under the effect of Talent Wind Dance Lightness, when full Sharpness at 4 layers is achieved, it can recover 11 points of Courage per second, and this value will be higher under the Haste attribute bonus. Courage Wind Ring consumes 16 points of Courage per second, meaning that without consuming other Courage, it can last close to 30 seconds with a net increase of 5 or fewer points of Courage per second.
Therefore, theoretically, through some energy recovery methods, we can infinitely extend the effect of Courage Wind Ring. As Courage is consumed, the damage of the Wind Ring doubles, causing damage equivalent to a major skill per second. After releasing Courage Wind Ring, Spiral Thrust, and Break Pursuit, you can use Gale Thrust once without cost and recover 10 points of Courage, which is achieved through the Chase the Wind talent. Meanwhile, Gale Thrust and Courage Wind Ring have a chance to trigger normal attack derivatives upon dealing damage, thereby recovering 10 points of Courage, which is the effect of the Wild Eye talent.

Additionally, the tearing effect caused by Gale Thrust has a chance to recover 5 points of Courage per damage instance, which is the effect of the Residual Heart talent. Break Pursuit also recovers Courage based on the number of enemies hit, while Wind Grace can instantly recover 70 points of Courage, and the ultimate skill Breaking Wind can recover 150 points of Courage. Therefore, when Courage is high, you can activate Courage Wind Ring and then try to use Gale Thrust to maintain full Sharpness. Since Break Pursuit has a short cooldown and can recover energy, try to activate Wind Grace after consuming 200 points of Courage, then release Spiral Thrust to maximize damage. If Gale Thrust triggers Wind Spiral, you can release Spiral Thrust earlier.
The ultimate skill Breaking Wind comes with a 50% Haste effect and can recover Courage and Sharpness. You can choose to sacrifice sustainability to deal high burst damage or release it when Courage is low to maintain the Courage Wind Ring for steady continuous output. In situations with many enemies, since the Courage recovery effect of Break Pursuit is significantly increased, the tearing effect will also spread to all enemies, increasing the Courage recovery rate, allowing for more frequent Courage consumption and faster skill rotation. Courage Wind Ring itself is an AOE skill, so in cases with many enemies, the Rebuild Stream becomes even more terrifying.

That concludes the introduction of the Star Trace Resonance Rebuild Stream. Therefore, the Rebuild Stream is a class with relatively stable output. Although it doesn't have ultra-high burst damage, it can maintain a high damage level most of the time. Players can follow the above combinations when using it.
