The ZZZ 3.4 banners start on 2 December 2026 (expected) with Sunbringer, an S-Rank Fire Armorer, in Phase 1, then the Honkai: Star Rail collab agents Kafka (Electric Anomaly) and Robin (Ether Defense). The three new agents are official. The phase order, the reruns (Remielle, or a Cissia, Vivian and Ju Fufu selector), a free Robin and a free W-Engine for 200 pulls are leaks and rumours as of 11 November 2026, and this page labels them that way every time.

Legion Gacha put the pieces together on 28 October 2026, four days after HoYoverse posted Kafka’s Agent Record and while the 3.4 beta was being picked apart. His video is a roundup rather than a kit guide: lineup, reruns, the Robin giveaway, her signature W-Engine and the two Drive Disc sets found in the beta. We read every number off his slides and the beta cards rather than his voice-over, because in two places the two disagree, and we checked the rerun history against the ZZZ banner schedule this site keeps.

ZZZ 3.4 Phase 1 and Phase 2: Banners and Dates

HoYoverse has not published the 3.4 phases. The dates below follow 3.3, whose two phases ran three weeks each (21 October and 11 November 2026), and the order is the leak posted by Seal on 22 October 2026: an Eldreda Sunbringer banner with a Remielle rerun first, a Lindverne Sunbringer banner second, and Kafka and Robin on a collab banner that stays up longer than one phase.

The two leaks do not fully agree. Seal’s puts Remielle in Phase 1, while the slides Legion Gacha showed six days later carry a Cissia, Vivian and Ju Fufu selector rerun (below). They can both be true, a selector Channel sitting next to the phase banners, but only the special programme will say. We update this table the day it airs, and the banners page gets the official phases with live countdowns.

ZZZ 3.4 Banner Lineup: Who Is Coming

Phase 1 is Sunbringer’s, according to Legion Gacha, with the Honkai: Star Rail collab alongside. That is three limited S-Rank agents in one version, which is why he calls it the most stacked lineup the game has had. Here is what is confirmed about each, and where it comes from.

Sunbringer is three knights of Roscaelifer, Eldreda, Lindverne and Dracaene, played as one agent. She deals Sharp DMG that scales on DEF, like Claret, and both new Drive Disc sets below are written for that kind of damage. Kafka is the Electric Anomaly half of the collab: Legion Gacha expects her to pair with Vivian, which is one reason he thinks Vivian is in the rerun. Robin is the support that ties it together. Our Robin guide shows her on top of every Sunbringer squad in the beta calcs.

Which Agents Rerun in ZZZ 3.4? Cissia, Vivian and Ju Fufu

The leak is a single rerun Channel with three agents in it: Cissia, Vivian and Ju Fufu. Legion Gacha describes it as a selector: the first S-Rank you get is the one you chose, and the first W-Engine on the matching W-Engine Channel works the same way. His slide marks the guarantee as rumoured. The format already exists in the game; he shows an earlier one with Alice, Soldier 0 Anby and Astra Yao.

His slide lists Cissia as Electric Attack, Vivian as Ether Anomaly and Ju Fufu as Fire Stun, which matches our agent data. The banner history below is from the same schedule that powers our banners page, so you can see how long each has been away.

Legion Gacha’s reasoning for Vivian and Ju Fufu is the buffs: both are expected to get changes in 3.4, and HoYoverse tends to rerun an agent alongside a buff. Vivian would sit next to Kafka in Electric Anomaly squads, and Ju Fufu would be the Stunner for Sunbringer, the stand-in our Robin guide already pointed to because of her 3.4 potential unlock. Cissia is the one with no buff attached; Legion Gacha simply notes she has never had a rerun since her 2.7 debut. Our tier list shows where all three sit today.

If the selector holds, the choice is a squad question more than a strength one. Cissia is an on-field Electric damage dealer whose best W-Engine is her signature, Serpentine Seeker. Vivian is an Ether Anomaly agent who works best next to another Anomaly agent, which is exactly what Kafka is; her signature is Flight of Fancy. Ju Fufu is a Fire Stunner, and her signature, Roaring Fur-nace, is the one to take if you plan to build Sunbringer with the new Stun set. If you only want one, pick the agent your current squads are missing rather than the one with the newest buff, and check her build page for the full W-Engine and Drive Disc picks before you spend.

When Does ZZZ 3.4 Start?

On Wednesday 2 December 2026, expected. Version 3.3’s second phase, Severian and the Norma rerun, runs until 1 December 2026, and every version so far has started the day after the previous one’s last banner ended. Each 3.3 phase lasted three weeks, which puts the 3.4 Phase 2 switch on 23 December 2026 and the end of the version on 13 January 2027. HoYoverse gives the exact day and both phases at the 3.4 special programme, which had not aired as of 11 November 2026.

The collab itself was announced at the end of the 3.3 special programme on 9 October 2026, with Ellen and Astra Yao going to Honkai: Star Rail in exchange. Legion Gacha has also seen claims that the collab Channels might last longer than one version, or even stay permanently. Nothing in the leaks he shows supports that, and he presents it as hearsay.

Is Robin Free in ZZZ 3.4?

Probably, but HoYoverse has not said so. The source is a leaked post tagged “ZZZ 3.4” with Robin’s login art, which reads: “As usual, Robin will be given away this time. The specific acquisition time shall be subject to official announcement.” The art itself carries the Chinese words for a limited S-Rank agent obtained by logging in. Legion Gacha calls it all but confirmed; we call it a leak until the official notice.

The second rumour is about her W-Engine. Instead of the usual cumulative top-up event, which rewards spending money, 3.4 would run a cumulative pull event, and the milestone reward would be Robin’s signature W-Engine at 200 Signal Searches. His slide is careful: the requirement is rumoured, whether pulls on every Channel count is unconfirmed, and the missing top-up event is only expected. He guesses the top-up event is held back for the New Year, in 3.5.

Robin’s Signature W-Engine in the Beta

The beta card still calls it “Robin Test Engine”. At level 60 it reads Base ATK 713 and Percent HP 30%. Legion Gacha says 714 and 40% out loud; the card on screen says 713 and 30%, and so did the beta card in our Robin guide, so this page follows the card. The HP% stat fits her kit, which scales on HP.

Read together, the two lines tell you how Robin plays: she shields and fires Aftershocks from off-field, and the engine turns both into squad buffs. DEF matters more than usual here, because Sunbringer and Claret deal Sharp DMG that scales on DEF, so a 10% squad DEF buff is a damage buff for them.

The Two New Drive Disc Sets in ZZZ 3.4

Both sets come from the beta and have no English name yet in the footage. The first is for Fire Armorers, meaning Sunbringer. Its 2-piece gives DEF +16%. Its 4-piece raises CRIT Rate by 12%, and when the wielder deals Fire Sharp DMG, that damage ignores 16% of the enemy’s DEF. Legion Gacha reads “Fire Sharp” as Sunbringer’s own damage type; the beta lists her attribute as Genesis Flare, a Fire variant, so the set looks made for her. Compare it with the sets on our Drive Discs page.

The second is a Stun set. 2-piece: Energy Regen +20%. 4-piece: when the wielder’s CRIT Rate is at least 50%, CRIT DMG +30% and Daze +5%; and when the wielder is a Stun agent, an EX Special Attack or a Chain Attack raises the Sharp DMG of every squad member by 8% for 25 seconds, one instance per squad. Legion Gacha says the set gives 40% CRIT DMG; the card says 30%. The squad line is the interesting one: it is a Stunner’s set built to feed Armorers, which is Ju Fufu’s likely job next to Sunbringer.

How Many Pulls to Save for ZZZ 3.4

Legion Gacha’s advice is to start saving now, because 3.3 already asks for Phoenix and Severian and, by his count, gives fewer free pulls than usual. The arithmetic below uses the game’s own rules: 160 Polychrome per pull, a guaranteed S-Rank by pull 90 on an agent Channel and by pull 80 on a W-Engine Channel, and a 50/50 (agents) or 75/25 (W-Engines) on the first S-Rank.

The 200-pull event, if it is real, stacks with whatever you pull anyway: 180 pulls for a guaranteed Sunbringer already gets you most of the way to Robin’s W-Engine. Our pity calculator runs the odds from your own pity and guarantee, and the events page lists the Polychrome still on offer in 3.3.
