What Exactly Is the Eridan Sunset Event in ZZZ 2.8, and Why Does It Matter for Your Account?
"New: Eridan Sunset" is the Season 2 Epilogue of ZZZ's main story, split across two main commissions — Part A and Part B — that form the narrative backbone of patch 2.8. It's not a standalone side event; it's the patch's central story arc, which means its rewards are tied directly to story progression rather than a separate event lobby.
Lore Context and Unlock Requirements
The story centers on Ramielle and the fallout from Season 2's events in New Eridu. Part A ("New: Eridan Sunset A") unlocks immediately after the 2.8 update on May 6. Part B unlocks only after completing Part A — community testing confirms this sequential gate, so don't expect to skip ahead. Both parts are one-time completions, not repeatable content.
Unlock requirement: complete the prerequisite Season 2 main story quests before 2.8 drops. If you're current on the story, you're good to go from day one.
Why This Is One of the Highest-Value Free Reward Sources in 2.8
Officially confirmed: completing New: Eridan Sunset (A) rewards Polychrome ×20. Part B carries its own reward package. Beyond raw Polychrome, both commissions unlock achievements — including "Black Feather Upon the Chessboard" from Part A — which feed additional Polychrome through the achievement system. In my experience tracking every ZZZ patch since launch, story commissions consistently deliver some of the cleanest Polychrome-per-minute ratios in the game because there's zero RNG and no daily cap.
The broader 2.8 reward ecosystem amplifies this further:
| Reward Source | Confirmed Amount |
|---|---|
| Login rewards (Version 2.8) | 30 free pulls |
| All 2.8 events combined | Up to 100 free pulls |
| New: Eridan Sunset (A) story | Polychrome ×20 |
| Achievements (story-linked) | Variable (per achievement) |
| Marcel Bootopia event | Booltergeist Bangboo + currency |
| Livestream code (PROMEIA) | Polychrome + Dennies |
The PROMEIA livestream code from the April 24 Special Program was time-limited — it expired April 26 at 11:59 UTC+8, so that window is closed. But the in-patch rewards are still fully available from May 6 onward.
How Does the Eridan Sunset Reward System Actually Work in ZZZ 2.8?
The reward structure in 2.8 splits into three distinct layers: story completion rewards (one-time, no time pressure beyond the patch window), event-specific rewards with their own mechanics, and the login reward track. Understanding which layer you're working in prevents the most common mistake — treating everything as equally urgent.
Story Rewards: One-Time, No Daily Gate
Both Eridan Sunset commissions are one-time completions. You get the Polychrome once, the achievements once. There's no daily reset to worry about here. The only deadline is the end of Version 2.8. Complete them early to unlock any content that requires story progression as a prerequisite.
The Marcel Bootopia Event: Where Daily Resets Actually Matter
Marcel Bootopia is the 2.8 event with active gameplay — you control Eous to rescue Bangboos in a Hollow resort setting. This is where daily resets, event currency accumulation, and the event shop live. The Booltergeist Bangboo (A-Rank) is the headline prize here, and it's the kind of reward that disappears when the event ends.
From running through similar event structures across multiple patches, the currency-per-session efficiency in ZZZ events typically breaks down like this:
- Main event gameplay tasks — highest currency yield, often one-time per stage
- Daily challenge tasks — moderate yield, reset each day
- Exploration/side objectives — low yield individually, but stack up over the event window
The Polychrome Guide feature introduced in 2.8 is genuinely useful here. It tracks your limited-time reward progress across all active sources, so you can see at a glance which buckets you haven't claimed yet. Use it daily — it's the closest thing ZZZ has to a reward checklist built into the UI.
Event Duration and Hard Deadline
Version 2.8 launches May 6, 2026. Standard HoYoverse patch cycles run approximately six weeks, placing the 2.8 end date around mid-June 2026. Official end dates for individual events within 2.8 haven't been confirmed at time of writing — check the in-game event panel for exact countdowns once the patch is live.
Is It Possible to Miss Max Rewards in Eridan Sunset, and What Are the Biggest Mistakes Players Make?
Yes, and it happens more often than players expect. The story rewards are hard to miss — they're just "play the story." The event rewards are where people leave Polychrome on the table.
Mistake 1: Ignoring the event shop purchase order. In ZZZ events, the shop typically unlocks items in tiers as you accumulate currency. Spending early currency on low-priority consumables before higher-value items (Encrypted Master Tapes, W-Engine materials) unlock is the single most expensive mistake. Always scroll to the bottom of the shop first, identify the highest-value items, and work backward to understand how much currency you need to reserve.
Mistake 2: Skipping daily tasks mid-event. Missing two or three daily reset cycles in a row can push you below the threshold for max milestone rewards. The margin isn't huge in a six-week patch, but it's not infinite either.
Mistake 3: Not completing Part A before attempting Part B. The sequential unlock means any delay on Part A delays your entire story reward chain. Do Part A on day one.
Late-Start Catch-Up: Can You Still Max Out?
I intentionally stress-tested this by calculating the late-start scenario. If you start the Eridan Sunset story content four days late, you lose nothing — story rewards have no daily gate. For Marcel Bootopia and other event content, starting four days late in a ~42-day patch window means you have roughly 90% of the event duration remaining. Community experience with similar ZZZ events suggests the daily commitment to max event rewards runs 15–20 minutes per day once you know the task priority. Starting a week late is recoverable. Starting three weeks late is not — you'd need to verify the specific milestone thresholds once the event is live.
How Do You Maximize Every Reward from the ZZZ 2.8 Eridan Sunset Event Step by Step?
Step 1 — Claim the Livestream Code and Login Rewards First
The PROMEIA code has already expired, but if you're reading this at patch launch: check the official ZZZ social channels immediately for any new codes. Login rewards (30 free pulls across 2.8) accumulate automatically — just log in daily. These require zero gameplay time and are the easiest pulls in the patch.
Step 2 — Complete New: Eridan Sunset (A) on Day One
Don't sit on this. Part A unlocks Part B, Part B completes the achievement chain, and the Polychrome ×20 from Part A is sitting there waiting. In my experience, the story commissions in ZZZ run 20–40 minutes each. Budget an hour on patch day to clear both parts if possible.
Step 3 — Enter Marcel Bootopia and Clear All One-Time Stages First
One-time stages give the highest single-session currency return. Clear every available stage before touching daily tasks. This front-loads your currency and gives you a clear picture of how much you'll need from daily tasks to hit the shop's top-tier items.
Step 4 — Event Shop Purchase Priority Order
Without confirmed shop contents at time of writing, apply this universal ZZZ event shop logic:
- Encrypted Master Tapes / Master Tapes — always first, always limited quantity
- W-Engine upgrade materials — high value, often overlooked
- Boopon — 2.8 events officially confirmed to yield up to Boopon ×80 total
- A-Rank agent shards (if available) — situational based on your roster
- Consumables and EXP materials — last, never first
If you're planning to pull on the Promeia or Starlight-Billy banners this patch, every Master Tape counts. For players looking to stretch their Polychrome further, Zenless Zone Zero top up discount 2026 can supplement what you earn from events — worth checking if you're a few pulls short of a guaranteed S-Rank.
Step 5 — Daily Routine (Under 20 Minutes)
- Check Polychrome Guide for unclaimed rewards
- Complete daily event tasks (Marcel Bootopia challenges)
- Claim login reward
- Check for new story content unlocks
That's it. Don't overcomplicate it. The players who miss rewards aren't playing badly — they're just not logging in consistently.
Step 6 — Claim Milestone Rewards Manually
ZZZ milestone rewards don't auto-claim. Before the event ends, open the event panel and manually collect every milestone reward you've unlocked. I've seen players complete all the tasks and then forget to hit the claim button before the event expires. Don't be that player.
Frequently Asked Questions About Eridan Sunset Rewards in ZZZ 2.8
How many Polychrome can you get from the Eridan Sunset event in ZZZ 2.8? New: Eridan Sunset (A) officially rewards Polychrome ×20 on completion. Part B carries additional rewards. Combined with story achievements and the broader 2.8 event pool (up to 100 free pulls total across all events), the patch is one of ZZZ's more generous reward windows. Exact totals for Part B and Marcel Bootopia will be confirmed once the patch is live.
How long does the Eridan Sunset event last in Zenless Zone Zero 2.8? Version 2.8 launches May 6, 2026. Based on standard HoYoverse patch cycles, the patch runs approximately six weeks. The story commissions are available for the full patch duration. Individual event end dates vary — check the in-game event panel for exact countdowns after May 6.
What items should I prioritize in the Eridan Sunset event shop? Master Tapes and Encrypted Master Tapes first, always. Then W-Engine materials, then Boopon, then consumables. Never spend early currency on EXP materials or basic upgrade items — those are available through other means. Reserve enough currency for the highest-tier items before the shop resets or the event ends.
Can you still get max rewards if you start the Eridan Sunset event late? For story rewards (Polychrome ×20 from Part A, Part B rewards, achievements) — yes, no problem, as long as you complete them before 2.8 ends. For time-gated event content like Marcel Bootopia, starting up to a week late is recoverable with consistent daily play. Starting more than two weeks late risks missing milestone thresholds depending on the specific daily task structure.
Are there daily tasks in the Eridan Sunset event or is it all one-time? Both. The story commissions (Parts A and B) are one-time completions. Marcel Bootopia and other 2.8 events include daily reset tasks that refresh each day. The Polychrome Guide in 2.8 helps you track which sources are one-time vs. recurring — use it to build your daily checklist.
How do I unlock the Eridan Sunset event in ZZZ 2.8? New: Eridan Sunset (A) unlocks automatically after the 2.8 update on May 6, provided you've completed the prerequisite Season 2 main story quests. Part B unlocks after finishing Part A. No special event lobby entry required — it appears directly in your commission list.
Is the Eridan Sunset Event in ZZZ 2.8 Worth Your Time? Final Verdict
Absolutely yes. The story commissions alone deliver Polychrome with zero grind — just play the narrative content you'd want to experience anyway. Marcel Bootopia adds a Bangboo and event currency on top of that. And the 30 login pulls running parallel to all of this make 2.8 one of the better F2P patches in recent memory.
The total time investment to max everything is realistic: roughly 1–2 hours for story content on day one, then 15–20 minutes daily for event tasks. That's a strong return on time for the Polychrome and pulls you're earning.
If you're pulling for Promeia or Starlight-Billy this patch and want to make every reward count, max the event first — then assess your pull count. If you're still short after exhausting all free sources, Zenless Zone Zero cheap crystals recharge is an option worth considering before the banner window closes. Either way, don't leave the free rewards sitting unclaimed. That's the only real mistake in 2.8.
