Whether you're a newbie just stepping into the fray or a seasoned veteran, this guide's got everything you need: Buff breakdowns, boss strategies, and team recommendations. S-rank evaluations? We're grabbing them all! 

 

Buff Effects

Shiyu Defense comes with unique Buffs that shape how you fight. Get a grip on these, and you'll be racking up wins—and S-ranks—without breaking a sweat.

Peculiar Bloom: 

• Agent’s CRIT DMG is increased by 20% and Anomaly Proficiency increased by 40 points: Attack and Anomaly agents getting buffed.
• When the Support agent uses [EX Special Attack] or [Aftershock], the team's ATK and Anomaly DMG incresed. It's best to bring a Support unit in your team.

Overall, you can easily sweep all stages with Attack or Anomaly team, especially Anomaly team with the new character Yuzuha. If you have Jane, Yi Xuan and Yuzuha, it makes the run extremely easy.

 

 

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.

 

7th Frontier's Recommended Teams

Phase I Best Team 

Jane Team
Jane Doe	Vivian	Yuzuha
	Burnice	Astra Yao

 

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.

 

Phase I Alternative Teams

Miyabi	Yuzuha		Soukaku
Ellen Joe	Lighter		Atsra Yao
Evelyn

Miyabi Main-DPS team, the team make full use of Miyabi’s CRIT Rate &CRIT DMG increasing to offset the disadvantage of resistance.

Ellen + Lighter+Astro-Yao, the team can make full use of the invincible frame takes on Miasmic Jane’s combo attacks.

Evelyn’s unique combo frequency can deliver a continuous stream of firepower suppression. And she can coordinate with Stun agent to deal huge Daze, make enemies stunned quickly.

 

Phase II Best Team 

Yixuan Team
Yixuan	Pan Yinhu	Ju Fufu
		Atsra Yao
		Trigger

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.

 

Phase II Alternative Teams

Zhu Yuan	Qingyi	Atsra Yao
Yanagi	Vivian	Atsra Yao

Zhuyuan’s brust team: the team is veteran main DPS and the Stun agent deal huge DMG to enemies.

Yanagi+ Vivian, the two Anomaly-type DPS can trigger Miasmic enemies to break shield quickly to enhance the efficiency of passing the 2nd half of 7th frontier.
