The upcoming Zenless Zone Zero 3.4 banners put Sunbringer, Kafka, and Robin at the center of players’ saving plans. Sunbringer has been officially announced for Version 3.4, while Kafka and Robin have been revealed for the Honkai: Star Rail collaboration. December 2, 2026 is the expected version transition date. As of October 27, the complete phase order, rerun lineup, and collaboration acquisition rules remain unverified.
If you want more than one of these characters, decide which one gets your reserved pulls before adding signature weapons to the plan. Sunbringer and Robin’s beta kits already suggest a meaningful connection, but that does not make both characters and both weapons a necessary purchase.
ZZZ 3.4 Banners: Characters, Phases and Reruns
| Character or banner | Available information | Details still needed |
|---|---|---|
| Sunbringer | Officially announced to debut in Version 3.4. Nanoka’s beta entry describes a DEF-scaling Armorer. | Exact channel dates, featured A-Rank Agents, and phase assignment. |
| Kafka | Officially revealed for the upcoming Honkai: Star Rail collaboration. | Exact banner timing, duration, and channel rules. |
| Robin | Officially revealed. Her beta entry describes an Ether Defense Agent with shields and team buffs. | Final kit, acquisition method, and any giveaway conditions. |
| 3.4 rerun banners | A complete official lineup has not been verified. | Returning Agents and whether a special selection channel will appear. |
| Phase 1 and Phase 2 | The complete order remains unverified. | Which channels overlap and how long each remains available. |
The official Sunbringer preview confirms her 3.4 debut and describes her as the first Enchainer Agent. Kafka and Robin also appear on the official ZZZ website. Their reveals do not establish the complete banner schedule, so avoid treating announcement order as a confirmed Phase 1 and Phase 2 lineup.
ZZZ 3.4 Release Date
December 2, 2026 is the expected transition into Version 3.4. The Version 3.3 update announcement states that the current version ends that day at 06:00 (UTC+8). This supports the planning date, but it does not confirm when maintenance will finish or when each new character becomes obtainable.
If you need rewards earned between banners to afford a second character, wait for the individual channel dates before committing your first budget. For last-minute pulls, follow the countdown displayed on your own server.
Sunbringer and Robin: Who Should You Save For?
Sunbringer: A New Damage Dealer to Build Around
Nanoka’s current 3.4.1 beta entry describes Sunbringer as a DEF-scaling Armorer whose attacks combine the Sunbringer trio’s different roles. Her kit points toward a character you build a team around, making her worth watching if you want a new damage dealer and are prepared to invest in the accompanying lineup. The beta data does not yet establish how she compares with your existing teams at the same investment.
If Sunbringer is your main target, I would secure one copy before allocating pulls to duplicates or a signature W-Engine. Players who already have teams they enjoy can wait for her trial and practical comparisons. The trio’s presentation is a strong reason to be interested, but try the actual character if controlling a particular member is central to that interest.
Robin: A Support Candidate for DEF-Scaling Teams
Robin’s beta kit on Nanoka combines shields, off-field attacks, team damage buffs, and DEF support. That gives her a clear potential connection with Sunbringer: the DEF increase can contribute to Sunbringer’s offense, and their listed Additional Ability conditions are compatible. Both entries currently use test data from build 3.4.1 and may change before release.
For players planning a Sunbringer team, Robin deserves a place in the budget discussion. For an account whose damage dealers do not scale with DEF, part of her support package may be less valuable, so a universal must-pull recommendation would be premature. I would compare the pair against Sunbringer with existing teammates before sacrificing another wanted character to obtain both.
Some players in the Sunbringer preview discussion interpreted Robin’s appearance as a sign of their intended synergy. The beta mechanics now provide a more concrete reason to investigate that pairing. What remains unanswered is the size of the improvement over alternatives, especially at one copy each without signature equipment.
Kafka Banner: Avoid Buying Her Team Too Early
In a returning-player discussion, a player had obtained Velina and her signature W-Engine partly with Kafka in mind, then asked how to assemble their teams. Replies suggested future Kafka combinations, but those were predictions about an unreleased character.
Before pulling a possible Kafka teammate, ask whether you would still want that Agent if her final team preferences changed. An Agent who already improves a lineup you use has immediate value. An Agent purchased only for a speculative pairing spends Kafka’s reserve before you know the pairing’s actual benefit.
For a Kafka-first account, I would secure her acquisition budget before chasing another character’s signature weapon. Otherwise, you can end up owning the proposed supporting pieces without enough searches left for Kafka herself.
Should You Save for the Signature W-Engines?
Sunbringer’s beta signature W-Engine focuses on her own damage through DEF, CRIT Rate, and Fire-related offensive bonuses. Robin’s beta signature provides HP and adds team DEF and damage buffs through shield application and Aftershocks. Both entries still contain provisional naming, and their effects may change before release.
The useful budget comparison is Sunbringer plus her weapon versus Sunbringer plus Robin, if Robin requires pulls. One strengthens a character you already own; the other adds a teammate with her own support kit. Without final equipment comparisons and acquisition rules, there is not enough evidence to declare either purchase the better upgrade. For players also saving for Kafka, I would protect that character reserve before funding either weapon.
Is Robin’s W-Engine a Free Pull Reward?
The community discussion about a milestone reward remains separate from Nanoka’s weapon data. The database describes what the weapon does, not whether it will be given away. Commenters also disagree about the value of such a reward: players already planning several purchases see a bonus, while players who obtain their targets early may need unwanted extra searches.
If a milestone is confirmed, calculate how many additional searches it requires after obtaining your intended targets. A hypothetical 200-search reward would cost another 70 searches if you finished at 130, equivalent to 11,200 Polychrome without saved tapes. That threshold is only an example, not a confirmed 3.4 requirement. An early win is still a good result even if stopping means leaving a milestone reward unclaimed.
How Many Pulls Should You Save for ZZZ 3.4?
The regular Exclusive Channel guarantees an S-Rank within 90 searches. Losing the featured 50/50 guarantees the featured Agent on the next S-Rank, and each search costs one Encrypted Master Tape or 160 Polychrome. These existing rules are documented in the Signal Search Wiki. They are not automatically the rules of a new collaboration channel.
| Regular Exclusive Channel status | Maximum additional searches for the featured Agent | Polychrome equivalent without tapes |
|---|---|---|
| 0 pity, no featured guarantee | 180 | 28,800 |
| 0 pity, featured guarantee active | 90 | 14,400 |
| 60 pity, no featured guarantee | 120 | 19,200 |
| 60 pity, featured guarantee active | 30 | 4,800 |
At 60 pity without a guarantee, 50 tapes plus 8,000 Polychrome provide 100 additional searches. The regular-channel worst case is 120, leaving a shortfall of 20 searches or 3,200 Polychrome. These are maximum-cost budgets, not expected spending.
Keep existing pity separate from your collaboration calculation until sharing is confirmed. Count currency already owned separately from projected event income, and do not combine Agent and W-Engine counters. A plan that works with inherited pity may no longer cover your target if a new channel starts from zero.
Should F2P Players Skip the Current Banners?
Not every account benefits from the same skip list. In one F2P account-advice thread, replies favored a returning teammate because they expected that character to help several Agents the player already owned. That is advice for a particular roster, but it raises a useful question: would the purchase complete an existing team or start another unfinished project?
If a current Agent completes a lineup you want to play now, decide whether that immediate benefit is worth reducing your upcoming-character budget. If your teams already meet your needs, postponing an optional signature weapon may be the easier compromise. Low spenders should use a fixed spending limit rather than assuming every shortfall will be covered by another purchase.
I would not pull on an unwanted Agent just to build pity. An early featured S-Rank can consume the guarantee you intended to save. Keeping the currency unspent preserves your choice of target.
FAQ
Will Robin be free in ZZZ 3.4?
Free acquisition has not been established by the material reviewed here. Her beta kit describes gameplay rather than how to obtain her. Keep a reserve until an official announcement explains any giveaway and its eligibility requirements.
Will Kafka and Robin’s banners be permanent?
That remains unverified. Community discussion compares other HoYoverse collaborations, but their availability rules do not establish ZZZ’s. An extended banner duration would also differ from permanent availability.
Can I pull Sunbringer first and save for Kafka afterward?
Build that plan around confirmed channel dates and the income available before Kafka’s deadline. If the channels overlap heavily, there may be less time to rebuild your balance than you expect. Until the schedule is published, prioritize the character you would most regret missing.
Will searches before 3.4 count toward a collaboration reward?
Do not assume they will. Pity carryover and an event’s search counter are separate systems. The event terms must specify the eligible channels and counting period.
Set Your Stop Point Before Opening the Banner
Reserve the amount needed for your first-choice Agent under the confirmed channel rules, then spend elsewhere only from the remaining balance. If Sunbringer is your priority, obtain her before deciding whether Robin or a signature weapon is the better next purchase. If Kafka is your priority, delay speculative teammates and optional weapons. Once you reach the amount reserved for your next target, stop spending elsewhere.
