2.4 Arrives: ZZZ’s New Agents, W-Engines, Regions, and Events Deliver End-of-Year Bonanza!

The long-awaited Zenless Zone Zero 2.4 “On the Precipice of the Abyss” update is now live, and it’s easily one of the game’s most ambitious releases to date. HoYoverse is giving players not only two new S-Rank agents, a web of high-stakes events, and a major story chapter—but also 600 Polychrome in compensation for the rollout and bug fixes. Here’s a deep dive into everything this massive patch delivers.

💎 Free Stuff First: 600 Polychrome Compensation

Before you even talk meta or banners, Version 2.4 hands you 600 Polychrome just for being around:

• Server Update Compensation – 300 Polychrome

• Issue Fix Compensation – 300 Polychrome

👉 Requirements for both:

• Reach Inter-Knot Lv. 4 before 2025/11/26 06:00 (UTC+8).

The update mails arrive after maintenance, last 30 days, and:

• General update comp is claimable until 2.4 ends (2025/12/30 06:00)

• Issue fix comp must be claimed before 2025/12/26 23:59 (UTC+8)

So yes, log in. Don’t let 600 Polychrome rot in your inbox.

🧨 New S-Rank Agents — Why Dialyn & Banyue Matter

🔩 Dialyn (Physical • Stun) — The “Turn My Chain into an Ultimate” Monster

Dialyn is built to break bosses open:

• Specializes in Stun: increases enemy Daze duration and Stun DMG Multiplier.

• Under specific conditions, when she opens a Chain Attack window with certain skills, the next character’s Chain Attack upgrades directly to an Ultimate.

• In practice: she sets the table, your carry walks in and slams a free nuke.

Banner:

• Available on the “Voice of the Once-Spoken” Signal Search.

Perfect for players who love tempo control and gigantic synchronized bursts.

🔥 Banyue (Fire • Rupture) — Combo-Heavy Fire Main DPS

Banyue is your new Fire Rupture blender:

• Strings together different Basic attack chains that flow into EX Specials, letting you swap routes depending on the situation.

• Designed to dish out massive, continuous Fire DMG, not just short bursts.

• Great for burning through long boss HP bars and Rupture-friendly content.

Banner:

• Available on the “Through Night’s Inferno” Signal Search.

If you want a flashy, aggressive Fire carry, this is the banner to watch.

🔧 New S-Rank W-Engines & Bangboo

W-Engines

• Yesterday Calls (Stun) – S-Rank, supports stun-focused kits like Dialyn.

  • Banner: “Dissonant Sonata” Signal Search.

• Wrathful Vajra (Rupture) – S-Rank, tailored for Rupture DPS like Banyue.

  • Banner: “Dazzling Choir” Signal Search.

Meta translation: if you’re pulling Dialyn or Banyue and want them at full power, you’re looking at these W-Engines too.

Bangboo

• S-Rank Birkblick – via “An Outstanding Partner” Signal Search.

• A-Rank Bild N. Boolok – via the “En-Nah’ Chess Saga” event.

More Bangboo = more passive buffs, more silly robot noises, more ways to optimize endgame runs.

📘 Story: Season 2 Steps Onto the Edge

Season 2 Chapter 5 — “On the Precipice of the Abyss”

• Permanent main story chapter after 2.4.

• Requirement: clear Season 2 Chapter 4 “Memories of Dreams Bygone.”

• You can also pre-view Season 2 via Advance Screening once you unlock Notorious Hunt in Season 1 Chapter 2 – Intermission.

Expect heavier themes, new bosses, and more of that “New Eridu is not okay” energy.

Trust & Quality Time (Banyue & Dialyn)

• New Trust and Quality Time events for both new S-Ranks.

• Permanently available after 2.4.

• Requirements: own the Agent + complete their required story nodes (check Workbench → Partner Archive).

If you pull them, don’t forget to farm their stories — it’s free lore and free resources.

🐞 Bug Fix Snapshot

The patch quietly nukes a ton of annoyances:

• Agents: animation weirdness on Seed, Kama’s entrance positions, Alice stair-walking with Sea of Thyme, Lucia’s leg accessories, random model glitches, strange turning angles in city scenes.

• Enemies: audio problems fixed for specific mobs.

• Systems: wrong Agent list sorting, “new” indicators not clearing, incorrect icon displays.

• Gameplay: Hollow Zero kill tally bug, Tsukishiro Yanagi damage bug with Moonblade gear, Reckless Bangboo spawn issue.

• World/Other: NPC visual issues, text typos, and language polishing across missions and UI.

Nothing flashy, but all the little paper cuts that make the game feel off? Many of those are gone.

TL;DR — What You Should Actually Do in 2.4

1. Log in and grab 600 Polychrome.

2. Decide: Dialyn, Banyue, or both? Plan your pulls (and maybe their W-Engines).

3. Clear up to Season 2 Chapter 4 so you can jump into Chapter 5 and new zones.

4. Mark the double reward windows (Area Patrol & Combat Simulation) on your calendar.

5. Run the “En-Nah” Chess Saga and Neo Golden Mecha events for their unique rewards and areas.

6. If you’re an endgame enjoyer, prep stun comps, Fire/Ice DPS, and Bangboo setups for Shiyu Defense, Deadly Assault, and Hollow Zero.
