Earning six stars unlocks all the rewards, making it easy even for non-hardcore players to complete the game with a full haul. This article provides a comprehensive Fatal Raid guide, including event rules, buffs, boss mechanics breakdowns for each stage, and recommended teams to help you complete the game effortlessly.

Fatal Raid Event Rules

Fatal Raid is a periodic, high-difficulty challenge in Zenless Zone Zero, alternating with the "Shiyu Defense" mode. It refreshes every two weeks, fixed at 4:00 AM (server time) on Fridays.

Key Rules:

Reusing Agents and Bangboos is prohibited—you'll need to be flexible with your lineup.

There are three boss battles, each with three stars.

A full star count is nine, and the required reward is six—you don't have to push yourself too hard to reap all the rewards.

This mode not only tests your understanding of characters and lineups, but also emphasizes combat maneuverability and adaptability.

Buff Analysis

The event offers three different buffs. Choosing the right one can maximize your effectiveness:

1. Blazing Assault

When one or two offensive agents are in your team, your team's damage is increased by 20%/40%.

After a critical hit, Electric damage is increased by 30%; Offensive agents' critical hits also increase their damage by an additional 40% for 5 seconds.

This is ideal for high-critical hit lineups, especially those that rely on Electric bursts.

2. Exquisite Craftsmanship

All agents' damage is increased by 20%, and physical damage is increased by an additional 20%.

When an enemy is inflicted with an Ailment, their Defense is reduced by 10% for 10 seconds. If Confusion is triggered, Defense is further reduced by 25%.

Best suited for teams with abnormal status, allowing abnormal agents like Jane and Vivian to maximize their power.

3. Transformation

Ultimate skill damage increased by 30%.

When using the ultimate skill, the team's attack damage is increased by 15% for 15 seconds.

When enemies are stunned, their stun damage is increased by 35%.

Recommended for teams that rely on ultimate burst and crowd control, requiring high maneuverability.

Stage 1 Boss: Polluter

Boss Information

Weaknesses: Physical, Lightning

Resistance: Ice

Special Mechanic:

Hiting a Polluter with a defensive assist grants the entire team the effect of Judgment.

Shooting down a Polluter with an aerial attack grants additional Judgment stacks.

Each stack of Judgment increases the team's critical damage by 8%, stacking up to 6 stacks.

Attribute abnormality damage reduced by 25%.

The key to combat is to effectively utilize defensive assists and aerial attacks to quickly stack Judgment and increase critical damage.

Recommended Lineup

Due to the Polluter's reduced damage from abnormalities, a pure DPS or Assault team is recommended:

Seed + Soldier 0 Ambi + Trigger (Physical + Electric burst)

Harumasa + Trigger + Butler (Assault core combination)

Nekomata + Lina + Butler (Efficient lineup for beginners)

Note that the Polluter frequently enters invincibility frames, so maximizing your score requires skillful control and timing.

Phase 2 Boss: Miasma Demon

Boss Information

Weaknesses: Aether, Physical

Resistance: Fire

Special Mechanic:

When affected by abnormalities, take an additional 8% damage, stacking up to 6 times.

Activating the Miasma Shield clears all abnormalities and increases shield resistance.

Detonating Miasma Pools is key to scoring, and you must successfully detonate at least 5 without being hit.

Anomaly Agents are crucial in this phase, and effective use of Miasma Pool explosions can quickly boost your performance score.

Recommended lineups

Focus on stacking abnormalities and dealing ether damage:

Jane + Vivian + Yuzuki (Best lineup, efficient abnormality team)

Miyabi + Vivian + Yuzuki (alternative for when Jane is unavailable)

Yanagi + Vivian + Yuzuki (more control-oriented lineup)

Additional options: Alice, Yuzuha, and Misano can provide additional control and burst.

Stage 3 Boss: Miasma Priest

Boss Information

Weakness: Aether

Resistance: Ice

Special Mechanic:

When switching phases, gain +10% abnormal resistance and +30% critical damage received. Maximum stacking: two.

Succeed three consecutive defensive assists to earn high Performance Points.

This player enters a Miasma Shield state, allowing them to move quickly and perform a three-hit combo, all with a gold indicator, making them ideal for counterattacks with defensive assists.

The battle rhythm is centered around defensive assists, requiring mastery of blocking and counterattack timing.

Recommended Lineups

Aether's weakness makes the following combinations perform best:

Yixuan + Seed + Butler (Dual Assault Core, balancing burst and control)

Zhu Yuan + Astra Yao + Qingyi (Powerful Ultimate Team)

Ju Fufu + Pan Yinhu + Bellion (Burst Team with Transformation Buff)

If you lack a core Agent, you can try Evelynn Support Team or No. 11 Fire Team, but these require higher skill levels.

Practical Clearing Tips

Diversify your lineups: Since you can't reuse Agents and Bangboos, prepare at least three main lineups covering physical, aether, and electric attributes.

Flexibly Choose Buffs: Choose buffs based on your team's characteristics. Critical Teams are suitable for Scorching Assault, Abnormal Teams are suitable for Ingenuity, and Ultimate Teams are suitable for Transformation.

Focus on Performance Points: In addition to killing bosses, skillfully utilizing mechanics (such as defensive assists and detonating miasma pools) can earn additional points and quickly reach three stars.

Be familiar with boss moves: especially the Defiler's invincibility frame and the Priest's triple combo. Mastering these patterns will allow you to easily counter them.

Summary

This "Zenless Zone Zero" "Fatal Assault" event isn't extremely difficult. With the right strategy and team composition, you can easily reap all the rewards.

Defiler: A Physical/Electric Burst team focused on critical hit stacks.

Miasma Demon: An Ether/Physical Anomaly team focused on mastering the Miasma Pool mechanic.

Miasma Priest: An Ether Burst team focused on defense, assists, and counters.

The event offers generous rewards, and both veterans and newcomers can easily reach full stars by utilizing the mechanics and recommended lineups. Agents, are you ready for the challenge?
