Hey, Proxies! A fresh round of the "Deadly Assault" event is here, and I've got your back with a full guide and the best team setups to tackle it. Nine stars? We're grabbing them all!
From July 11 to July 25, Zenless Zone Zero is hosting the latest Deadly Assault event, and I'm here to break it down for you. This event isn't too brutal overall—you can get all the film rewards as long as you get six stars in the three levels. 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. Let's jump right in!
What We Have
Deadly Assault Rules
Deadly Assault is one of Zenless Zone Zero's tougher challenge modes, running from June 13 to June 27. It refreshes every two weeks on Fridays at 04:00 (server time), alternating with the Shiyu Defense event. Here's the catch: you can't use duplicate agents or Bangboos in your lineups. The event features three stages, with a total of nine stars up for grabs. Snagging six stars is enough to claim all the Polychrome rewards, so don't stress if you can't max it out.
To give you an edge, the event offers three buff effects to choose from: Meditation, Illusory Surge and Rapid Aid. These buffs can seriously amp up your team's performance—it's all about picking the right one for your playstyle. Let's break them down next, along with strategies for each stage.

Stage 1 Boss Analysis & Team Recommendations
Boss: Miasma Priest
Weaknesses: Ether Resistance: Ice
Current Intel:
- When the Miasma Priest switches phase, their Anomaly Buildup RES increases by 10% and CRIT DMG taken increases by 30%.
- This effect can stack up to 2 times and is cleared when Miasma Shield breaks.
Strategy:
This boss is tailored for 2.0 characters such as Yixuan, who has an easier time breaking through the Miasma Shields. If you do not have her, you can use any other Ether Agent.
There are two key mechanics to watch out for:
Consecutive Yellow Attacks: During these sequences, simply spam character switches for Parry Assists. They don't consume Support Points, earn you Operation Score, and can force the enemy into a Staggered State, increasing the damage it takes.
Miasma Shield: The boss will activate a Miasma Shield, greatly reducing damage taken and becoming immune to Imbalance. Regular attacks will chip away at the shield, but Parry Assists, Perfect Dodges, Counterattacks, and Ultimate Skills are much more effective. So don't panic—red glow means dodge, yellow glow means parry, and feel free to switch to a support unit and unleash their Ultimate to break the shield faster.
Team Recommendations
The enemy gains increased Anomaly Resistance and Ice Resistance after each phase transition, effectively shutting out Anomaly comps like Miyabi teams. With its Ether Weakness, it's recommended to run a Yi Xuan Team or Zhu Yuan Team.
If you don't have Yi Xuan or Zhu Yuan, consider using a Chase Team, Ellen, or even a 11 Soldier Fire Team as alternatives.

Stage 2 Boss Analysis & Team Recommendations
Boss: Corrupted Overlord - Pompey
Weaknesses: Fire Resistance: Electric
Current Intel:
- Boss enemies gain 1 stack of Battle-Hardened every 10s, increasing their DMG dealt by 20% and stacking up to 3 times.
- When inflicting Attribute Anomaly, removes 1 stack of Battle-Hardened and increases their DMG taken by 15% for 20s.
Practical Rotation (Ben-Bernice Chaos Combo Example):
- Engagement Start: Caesar Hold ATK to group enemies → Bernice applies Pyro Attribute Anomaly → Ben enters field to trigger Chaos Burst.
- Amplification Control: When Pompey gains 2-3 Corrosive Amplification stacks, immediately reapply Anomaly to maintain Vulnerability debuff uptime.
- Golden Triple Kick: After Perfect Dodge, instantly switch to Ben to inflict Stagger, then execute Chain Attack.
- Stagger Window: Unleash all Ultimate skills within the 5-second Stagger phase to maximize damage output.
Team Recommendations
For this stage's Operation Score objective: Focus on Perfect Dodge. Evelyn and Jane can engage normally.
Corrupted Overlord – Pompey exhibits extremely high attack frequency. Maintain precise rhythm – mistiming may result in combo lockdown.
No Fire attribute agents? Non-Electric teams (e.g. Ice squads) can still force through.

Stage 3 Boss Analysis & Team Recommendations
Boss: Boss: Notorious - Dead End Butcher
Weaknesses: Ice & Ether
Current Intel:
- DMG dealt to boss enemies by Attribute Anomaly is increased by 50%.
- While Notorious - Dead End Butcher is in Ether Enhanced state, the DMG it takes is reduced by 15%, and the Daze value dealt by Agents to it is reduced by 30%.
- Triggering Disorder on Notorious - Dead End Butcher immediately forces it to exit the Ether Enhanced State.
Phase Breakdown:
Opening (0-10s): Aggressive Stagger Rush: Commit all skills immediately – no resource saving required.
Deadlock Mode (10-90s): "Blue Light" Energy Projectile: Execute Perfect Dodge or switch to Caesar to tank with Super Armor (prevents interruption).
- Ice Team:
→ Miyabi Charged Slash + Lycaon Heavy ATK for shield break
→ Maintain Anomaly uptime
→ Shave off 1 Corrosive Amplification stack via Ice Anomaly every 12s - Ether Team:
→ Qingyi Break → Nicole Gather → Zhu Yuan Burst
→ Use Disorder chains to remove stacks
Stagger Burst Window: When Stagger bar ≤30%: Save all Ultimates. During 5s Stagger phase: Unload Chain Attack > Ultimate Skill for max DPS
Cycle: Repeat "Stack Removal → Stagger → Burst" until elimination.

Agent Substitution Guide (Roster Limitations)
• Main DPS Replacement: No Miyabi? → Use Ellen (Ice teams) or No. 11 (Ether teams).
• Breaker Role Gap: No Lycaon? → Substitute Lighter, Koleda, or Qingyi.
• Support Alternative: Lacking Soukaku? → Select Caesar, Lucy, or Nicole.
Core Viability Rule:
Any squad containing at least one Ice/Ether DPS + one Anomaly/Breaker agent with aligned support buffs can achieve full rewards.
Conclusion
This concludes our tactical briefing! Enemies this phase exhibit predominant Ether vulnerability, with Stages 1 and 3 featuring Ether-weak targets. Additionally, Stage 2 carries Fire weakness while Stage 3 introduces supplementary Ice vulnerability. Electric and Physical attributes remain unviable in the current combat environment.
For Proxies with limited agent investment or roster depth, we recommend prioritizing a 6-star total clearance by either securing 3-star completions in two select stages or achieving 2+ stars consistently across all three engagements.
