Zenless Zone Zero Endless Tower Floor 1-25 Guide

Zenless Zone Zero Endless Tower Floor 1-25 Guide: Introduction

The Endless Tower in Zenless Zone Zero is one of the most grueling combat challenges the game has to offer, designed to test players’ endurance, strategic thinking, and mastery of combat mechanics. This high-intensity mode pushes Agents to their limits with wave after wave of increasingly difficult enemies, requiring precise execution and careful resource management to survive. Among its most intense variations is Endless Tower: The Last Stand, a limited-time version of the challenge that raises the stakes with unique battle conditions and exclusive rewards. Only the most prepared and skilled players will be able to overcome its relentless trials.

To gain access to the Simulated Battle Trial and take on this formidable challenge, players must first complete the “The Midnight Pursuit” mission and reach Inter-Knot Level 36.

With each floor cleared, the difficulty intensifies, demanding quick reflexes, precise dodging, and effective skill rotations to survive.

Success in the Endless Tower isn’t just about brute force—it requires a deep understanding of each Agent’s abilities, synergy between team members, and mastery of elemental interactions. Players must also consider their resource usage carefully, as mismanaging skills, dodges, or cooldowns can mean the difference between victory and failure. As a limited-time mode, Endless Tower: The Last Stand offers exclusive event rewards that can significantly boost a player’s progression, making it a key activity for those looking to enhance their teams and gear.

Whether you’re aiming to climb the rankings, earn valuable upgrade materials, or simply test your combat prowess, this guide will provide all the essential details to help you conquer the Endless Tower. From team-building tips to survival strategies, we’ll break down everything you need to know to maximize your performance and claim the best rewards before the event ends. Prepare yourself—the fight ahead is not for the faint of heart.

Endless Tower: The Last Stand Duration

The Endless Tower: The Last Stand is a time-limited challenge mode in Zenless Zone Zero, available for a little over 42 days following its initial release on January 22, 2025. Unlike the standard Endless Tower, which serves as a long-term test of endurance, The Last Stand introduces new mechanics, increased difficulty, and exclusive rewards that are only accessible during its event period. Players aiming to take on this challenge must strategize carefully, optimize their Agent teams, and push their limits before the event concludes. Since this mode is not a permanent fixture, those who want to reap its rewards should participate while it’s available, as it may not return in the same form in future updates.

Gameplay

In Battle Trial: The Last Stand, you take on the role of a Proxy, deploying your chosen Agents and Bangboos to clear multiple floors within the Simulated Battle Trial. This high-stakes mode tests both endurance and strategy, as your Agents’ Health carries over between floors. Unlike standard battles, where health may regenerate after each encounter, here it remains depleted unless a specific Battle Environment buff provides healing. The only way to fully restore your team’s health is by completing an entire phase, which consists of multiple floors.

Before starting each floor, you must carefully select a team of Agents and Bangboos that will remain fixed for a set of 10 floors. While you won’t be able to swap them out mid-phase, you can still adjust your strategy and formation using the characters you’ve already chosen. This makes team composition critical—understanding your Agents’ strengths, weaknesses, and synergy is essential to making it through each challenge. Since floors introduce different enemies and mechanics, assessing the enemy lineup before each battle will help you plan your approach and ensure that your team is optimized for success.

One of the defining mechanics of The Last Stand is the Battle Environment system. Before each battle, you will have the option to select an environment that provides buffs to your Agents, enhancing their abilities in various ways. However, these environments often come with trade-offs, introducing additional challenges that can affect your performance. Some environments may grant increased attack power at the cost of defense, while others may enhance energy regeneration but reduce healing effectiveness. Choosing the right Battle Environment for your playstyle and team composition is crucial for overcoming the increasingly difficult encounters as you progress through the tower.

With its punishing difficulty, The Last Stand is designed to push players to their limits, rewarding those who can strategically manage resources, optimize team synergy, and adapt to changing combat conditions. Mastering this mode requires careful planning, precise execution, and a deep understanding of the game’s mechanics. Whether you’re aiming to climb the rankings or earn valuable upgrade materials, approaching each floor with a well-thought-out strategy will be the key to conquering this ultimate combat challenge.

Floors 1-5

In the initial phase of Battle Trial: The Last Stand, enemies exhibit a Fire weakness while possessing Electric resistance. This means that using Fire-based Agents will maximize damage output, while Electric attacks will be less effective. Understanding enemy resistances and weaknesses is crucial to clearing floors efficiently and conserving resources for later battles.

Battle Environments & Their Effects

Each Battle Environment introduces unique buffs and debuffs, influencing combat strategy. Players must carefully select an environment that complements their team composition:

Elysium on Edge: Triggering a Dodge Counter grants 1 Assist Point, but incoming damage is increased by 15%.

Fluid Soul: Grants an additional dodge chance, allowing more evasion opportunities, but Assist Follow-Ups deal 25% less Daze.

Unceasing Clash: Using an Ultimate grants Agents 20 Energy, enabling faster skill rotations.

Recommended Characters & Bangboos

To effectively clear the first five floors, selecting the right DPS, Stun, and Support units is essential. Below are the best choices:

Best DPS: Soldier 11, Miyabi, Jane, Burnice, Piper

Best Stun: Lycaon, Koleda, Caesar, Lighter

Best Support: Astra, Nicole, Soukaku, Lucy, Seth

Best Bangboos: Cryboo, Rocketboo, Red Moccus, Baddieboo, Knightboo

Sample Team Compositions

Balancing damage, crowd control, and survivability is key. Here are some sample teams optimized for the first set of floors:

Caesar, Burnice, Jane, Red Moccus – Balanced team with strong DPS and Stun.

Burnice, Astra, Miyabi, Knightboo – Sustain-heavy composition with strong Fire damage.

Lighter, Lucy, Soldier 11, Rocketboo – Prioritizes Dodge Counters and energy regeneration.

Floor Breakdown & Enemy Waves

Each floor presents increasing difficulty, requiring players to adapt their tactics:

Floor 1: Corrupted Bandit – Vicious Striker ×4, Corrupted Bandit – Greedy Ranger ×2

Floor 2: Hoplitai – Energized ×6

Floor 3: Hati – Energized ×3

Floor 4: Corrupted Bandit – Frenzied Maniac ×3

Floor 5: Notorious – Pompey ×1

How to Beat Floors 1-5

Floor 1: Eliminate the Greedy Rangers first, as they deal ranged damage. Then, group the melee units together and use AoE skills to clear them efficiently.

Floor 2: The Hoplitai are numerous but weak to AoE attacks. Use crowd-control skills and area-based damage to defeat them quickly.

Floors 3 & 4: Dodge Counters and Perfect Assists are vital against Elite enemies like Hati and Frenzied Maniacs. Time your dodges carefully to avoid heavy damage.

Floor 5 (Pompey – Notorious Boss): Pompey can be challenging due to its Disorder mechanic. Use Perfect Assists to mitigate damage and inflict Attribute Anomalies to trigger Disorder, significantly boosting your damage output.

Beware of Self-Destructing Enemies: Some normal enemies will attempt to self-destruct upon defeat. Make sure to dodge at the right moment to avoid unnecessary damage.

By carefully selecting the right Agents, managing resources efficiently, and adapting strategies for each floor, players can successfully clear this phase of The Last Stand and progress toward greater challenges.

Floors 6-10

As players progress through Battle Trial: The Last Stand, Floors 6-10 introduce new enemy resistances and weaknesses, requiring an adjusted strategy to efficiently clear each stage. Physical and Fire damage are highly effective in Floors 6-8, while Electric damage becomes essential for Floors 9-10. Meanwhile, Ice resistance is prevalent on Floors 6-9, with Fire resistance appearing on Floor 10, making careful team composition a crucial factor for success.

Battle Environments & Effects

Selecting the right Battle Environment can significantly impact performance. Each option provides unique advantages while introducing potential drawbacks:

Cleaving the Way: Boosts Assist Follow-Up Daze by 150%, making it ideal for stun-heavy teams. However, taking damage results in a 5% loss of Decibels.

Ravenous Gaze: Grants a 5% HP recovery on Perfect Dodge, improving survivability, but increases damage taken by 15%.

Beyond Decibels: Increases Decibel Generation Rate by 35%, accelerating energy gain for frequent skill use.

Recommended Characters & Bangboos

To effectively navigate these floors, assembling a team with strong DPS, Stun, and Support capabilities is vital. Below are the best choices for each role:

Caesar, Burnice, Jane, Red Moccus – Balanced team with strong Fire and Physical damage.

Burnice, Astra, Yanagi, Baddieboo – Fire-focused team with sustain and control.

Lighter, Lucy, Soldier 11, Rocketboo – Dodge-reliant build with strong assist synergy.

Harumasa, Rina, Yanagi, Agent Gulliver – Electric-oriented setup for later floors.

Floor Breakdown & Enemy Waves

Each floor features unique enemies with distinct behaviors, requiring adaptability:

Floor 6: Ionized – Doppelganger – Pulchra ×1, Hollow Thug – Rustler ×3

Floor 7: Ionized – Doppelganger – Bellum ×1, Hollow Thug – Looter ×3

Floor 8: Ionized – Doppelganger – Pulchra ×1, Ionized – Doppelganger – Mors ×1

Floor 9: Lumberjack ×1

Floor 10: Autonomous Assault Unit – Typhon Destroyer ×1

How to Beat Floors 6-10

Floor 6-8 (Doppelganger & Hollow Thugs): Start by eliminating weaker enemies first to reduce incoming attacks. Doppelgangers can be dangerous, so use stun mechanics and burst damage to minimize their offensive potential.

Floor 9 (Lumberjack Mini-Boss): This enemy hits hard and can chain attacks, making Perfect Dodges and counterattacks essential. Staggering it with Shock-inflicting skills will interrupt its patterns.

Floor 10 (Typhon Destroyer – Boss Fight): This Autonomous Assault Unit is heavily resistant to Fire and can unleash devastating attacks. Inflicting Shock will momentarily disable its offensive capabilities, providing a critical window for damage. Focus on avoiding its AoE assaults, and time Assist Attacks to maximize burst potential.

By adapting to the shifting enemy weaknesses, utilizing effective Battle Environments, and assembling an optimized team, players can successfully clear Floors 6-10 and continue their climb in The Last Stand.

Floors 11-15

As players advance into Floors 11-15 of Battle Trial: The Last Stand, enemy weaknesses shift, requiring a strategic approach to maximize damage output. Ether and Ice are the key damage types for this stage, making it essential to build a team that can take advantage of these weaknesses. Unlike previous floors, there are no elemental resistances, allowing greater flexibility in attack choices.

Battle Environments & Effects

Selecting the right Battle Environment is crucial for optimizing performance. Each environment provides unique buffs while introducing potential drawbacks:

Measured Pace: Grants 1 Assist Point on Dodge Counter, improving assist-based strategies, but increases Dodge cooldown by 0.5s.

Sharp Twirls: Triggers Vital View on a successful Perfect Dodge, enhancing reaction-based gameplay. However, Assist Follow-Ups inflict 25% less Daze, reducing stun potential.

Lethal Move: Increases Ultimate Damage by 30%, making it ideal for teams reliant on burst damage from Ultimates.

Recommended Characters & Bangboos

To handle the increasing difficulty of these floors, teams should focus on high burst damage, stun capabilities, and sustained support. The following Agents and Bangboos are the best choices for this stage:

Best DPS: Soldier 11, Miyabi, Ellen, Zhu Yuan, Jane, Burnice, Yanagi, Harumasa, Piper

Best Stun: Lycaon, Koleda, Qingyi, Caesar, Lighter, Anby

Floor 12: Fossor ×6, Sordidus ×6

Floor 13: Thanatos ×3

Floor 14: Metro Goblin ×3

Floor 15: Notorious – Marionette ×1

How to Beat Floors 11-15

Floor 11-12 (Multiple Enemies & Infested Units): Use AoE attacks to clear out grouped enemies efficiently. Melee units can overwhelm if left unchecked, so eliminating them first is key.

Floor 13-14 (Elite Enemies): These floors introduce tougher enemies that require Dodge Counters and Perfect Assists to mitigate damage and create openings for attacks. Managing enemy patterns is crucial to avoid unnecessary damage.

Floor 15 (Notorious – Marionette Boss Fight): Marionette summons clones, which must be eliminated quickly to weaken the primary target. Keep moving and use burst damage to prevent getting overwhelmed.

By adapting to enemy weaknesses, choosing the right Battle Environment, and assembling an optimized team, players can successfully conquer Floors 11-15 and push further into The Last Stand challenge.

Floors 16-20

As players push through Floors 16-20 of Battle Trial: The Last Stand, they will face increasingly formidable enemies with shifting elemental weaknesses. Fire damage is essential for Floors 16-18, while Physical and Fire are most effective on Floor 19. On Floor 20, Ether and Ice become the best choices. Additionally, Electric resistance on Floors 17-18 and Ice resistance on Floor 19 means players should avoid relying on those elements. With no resistances on Floor 20, flexibility in damage types is available for the final encounter.

Battle Environments & Effects

Choosing the right Battle Environment can help overcome difficult encounters:

Martyr’s Gambit: Boosts Assist Follow-Up Daze by 150%, making it great for stun strategies. However, DMG taken increases by 15%, so careful dodging is necessary.

Fluid Soul: Grants an extra dodge chance, improving survivability, but reduces Assist Follow-Up Daze by 25%, slightly weakening stun-based teams.

Glazed Form: Triggering an Ultimate grants a shield equal to 15% of Max HP, improving durability during burst phases.

Recommended Characters & Bangboos

Having the right team composition ensures smoother progression through these floors. The following Agents and Bangboos are recommended for their effectiveness in Fire, Physical, Ether, and Ice damage, as well as stun and support capabilities:

Floor 17: Hati – Energized ×3

Floor 18: Corrupted Bandit – Frenzied Maniac ×2, Corrupted Bandit – Wicked Wraith ×1

Floor 19: Ionized – Doppelganger – Pulchra ×1, Ionized – Doppelganger – Mors ×1, Ionized – Doppelganger – Bellum ×1

Floor 20: Notorious – Dead End Butcher ×1

How to Beat Floors 16-20

Floors 16-18 (Multiple Enemies & Elites):

Use Fire DPS to clear Ahriman and Hati quickly.

In Floors 17 and 18, Dodge Counters and Perfect Assists are key against nimble Elite enemies.

Floor 19 (Doppelgangers):

Interrupt Doppelgangers’ attacks using Stun to prevent them from overwhelming your team.

Avoid Ice DPS due to enemy resistance.

Floor 20 (Notorious – Dead End Butcher Boss Fight):

Dead End Butcher’s Ether Explosions deal significant AoE damage—dodge frequently and use long-range or quick burst damage strategies.

Ether and Ice damage will be the most effective for this fight.

By adapting to enemy weaknesses, selecting an appropriate Battle Environment, and forming a well-rounded team, players can successfully conquer Floors 16-20 and progress further in The Last Stand.

Floors 21-25

As players progress to Floors 21-25 in Battle Trial: The Last Stand, they will encounter enemies primarily weak to Physical and Ether damage, while Ice damage is ineffective. Choosing Agents and Bangboos that capitalize on these weaknesses will help clear these floors efficiently.

Battle Environments & Effects

Selecting the right Battle Environment can influence the flow of battle:

Cleaving the Way: Assist Follow-Ups inflict 150% more Daze, making it highly effective for stun-heavy teams. However, taking damage reduces Decibels by 5%, so careful play is needed to maintain energy.

Charged Nerves: Perfect Dodge triggers Vital View, enhancing survivability, but enemies gain Ambush, making them more aggressive.

Shifting the Terra: Ultimate damage is increased by 30%, ideal for teams that rely on high-burst damage ultimates.

Recommended Characters & Bangboos

The following Agents and Bangboos provide the best synergy for this set of floors:

Best DPS: Miyabi, Zhu Yuan, Jane, Burnice, Yanagi, Harumasa

Best Stun: Qingyi, Caesar, Anby

Best Support: Rina, Astra, Nicole, Soukaku, Lucy, Seth

Floor Breakdown & Enemy Waves

Each floor introduces different enemy types, requiring a varied approach:

Floor 21: Fossor ×3, Sordidus ×6

Floor 22: Ionized – Dullahan ×3

Floor 23: Ionized – Thanatos ×3

Floor 24: Ionized – Farbauti ×3

Floor 25: Ionized – Doppelganger – Jane ×1

How to Beat Floors 21-25

Floor 21 (Multiple Enemies): Use AoE attacks to handle the Sordidus swarms while keeping distance from Fossor’s attacks.

Floors 22-24 (Elite Ionized Enemies): Prioritize eliminating one target at a time to minimize incoming damage. Dodge Counters and Stun abilities will help control the battlefield.

Floor 25 (Doppelganger Boss Fight): Doppelganger Jane mirrors attack patterns from the original, making Dodge Counters and Perfect Assists crucial for avoiding her powerful moves.

Maintain high HP before Floor 24, as the battles intensify and healing opportunities are limited.

By carefully selecting Agents and Bangboos, adapting to enemy weaknesses, and utilizing the right Battle Environment, players can overcome Floors 21-25 and advance further into The Last Stand.
