7th Frontier's Boss Analysis
Phase I Boss: Miasmic - Jane
Weakness: Physical | Resistance: Ether
The enemy on the 1st half of the 7th frontier is Miasmic - Jane. Her attack speed is extremely fast and she is very concealed, making it not easy to dodge. Fortunately, she will stop moving for a short time after she finishes her attacks, , allowing us to launch an attack.
Phase II Boss: Miasmic - Thracian
Weakness: Ether | Resistance: Electric
On the 2nd half of the 7th frontier, the enemy is the Miasmic - Thracian, who will charge himself and enhance his own attacks.
You can use more perfect dodges or guards instead of perfect parries, so its charge buildup will slower.

Facing the Miasmic - Jane 's combo, Jane became the best solution thanks to her exceptionally long invincibility frames during dodges. The new support agents Yuzuha, has fully unleashed the potential of this team.
The EX special Atttack of Yuzuha triggers a 20% increase in the team's ATK, perfectly matching the environmental buff. Meanwhile, Vivian’s Abloom mechanic further amplifies Jane’s CRIT DMG, allowing her to unleash single-round bursts exceeding one million damage.
The three agents forms a perfect action combo: Jane uses her dodge to avoid damage and deal counter-hits → Vivian stack Anomaly to enemies → Yuzuha strengthened the entire team → Jane triggered Passion state to kill enemy.

Even without benefiting from the Peculiar Bloom effect triggered by the support slot, Yi Xuan remains the top pick for the 7th Frontier’s second half thanks to her unique guard mechanic and exceptional part-breaking capabilities.
The Thracian’s attack telegraph is easy to spot, allowing Yi Xuan to chain perfect assists and quickly build up the Decibel Rating. Off-field Pan Yinhu steadily generates Ether, while Ju-FuFu boosts the team’s stun efficiency.
Yi Xuan’s Ultimate, Qingming Skyshade, is the finishing touch—dealing true damage that penetrates defenses against dazed bosses, bypassing even the thickest shields.
