Is Tangtang Worth Pulling in Endfield 1.6? Rerun Dates, Best Gear and Tips

Tangtang’s rerun in Arknights: Endfield, the Ancestral Spring Flows Anew banner, runs from October 29, 2026 at 12:00 to November 19, 2026 at 11:59 server time, and Zimen’s answer is that she is still worth pulling, above all for a small roster. He also changes how she should be built: the MI Security set, not Bonekrusha, which his calculator puts about 10% behind.

This guide follows Zimen’s 12-minute 1.6 Tangtang video, uploaded October 29, 2026, the day the rerun opened. Zimen builds his own damage calculator from the game’s stat and damage formulas, and the gear and Potential figures below are his. Skill and gear text is read off the game screens in his footage; his English subtitles are used where the voice is in Korean. Every in-game number is checked against this site’s Tangtang build page and gear data, and where the two disagree the page says so. The banner times come from this site’s banner schedule.

When is the Tangtang rerun?

The rerun is the second banner of version 1.6. It is listed in this site’s schedule as RE-Factor Headhunting #1, named Ancestral Spring Flows Anew, and runs for three weeks.

Times are server time, as this site’s banner schedule records them. Her signature handcannon, Brigand’s Calling, reruns alongside her from October 29.

Is Tangtang worth pulling in 1.6?

Zimen’s verdict is “an operator you won’t regret pulling,” with one condition attached to the account. With few limited operators, he strongly recommends her: she can lead a complete team of free operators, and the more 6★ operators you add, the more teams she fits. If you already own Infliction supports such as Arcane or Si, he says to think twice.

That SP cut is the reason she stays relevant. Her combo skill RIVER, TO ME! creates a Whirlpool, and every Whirlpool her battle skill converts into a Waterspout returns SP. Zimen counts it as one Infliction, one combo skill, 20 SP back: in effect, every Cryo Infliction the team applies costs 20 SP less.

He also calls her the closest stand-in for a Cryo Arcane: without Arcane, Tangtang copies Inflictions for the team, and for Cryo she applies them faster. His proof that she holds up in hard content is the official tournament.

She fits Rossi’s Physical teams as well, and our best teams page lists her in Yvonne, Last Rite and Xaihi squads. Si’s own best teams use her too, as our Si build guide shows.

How do you play Tangtang: dash cancel and dive attack

Her kit turns on the battle skill, and Zimen lists three things to master. First, IMA WAVERIDAAH! gives full super armor. It does not reduce damage, but even heavy stagger will not cancel the cast, so the damage window is guaranteed, or you can use it to sit through an attack.

Second, the moment a dive completes, the Waterspout is guaranteed. That allows two tricks: one extra battle skill always fits before the ultimate, and the battle skill can be dash-cancelled. Zimen calls the cancel “mandatory”. Without it, two battle skills and the ultimate end the window; with it, the dive attack fits too.

Third, the dive attack. If it does not come out reliably, basic attack once, hold the button and spam jump; it triggers by itself. Jumping first and then attacking does not work, as his side-by-side clip shows.

How do her talent and P5 really scale?

Zimen corrects a common reading of her talent, Riot Bringer. Its bonus is a damage increase, so it adds to the other damage increases from her weapon and gear sets; it does not multiply the Waterspout’s skill ratio by 1.6.

P5, Chief’s All-Eldritch Gaze, raises the ultimate’s DMG Multiplier to 1.15 times and adds +80% to Waterspouts created by the ultimate. Zimen’s point is that this stacks with the talent rather than replacing it: by his count the ultimate’s dive Waterspout reaches +140%, not +80%.

One disagreement: Zimen works from a 60% talent bonus, while the Riot Bringer text in this site’s data reads +40% DMG Dealt for those Waterspouts. The P5 text, +80% and 1.15 times, matches the data exactly. Either way, he adds that P5 matters less than it looks, because saving the ultimate for the end of a fight leaves no time for three dive Waterspouts.

Qingbo or Bonekrusha: what is Tangtang’s best gear?

Neither is the top pick in Zimen’s calculator. Bonekrusha, the set many players built at launch, “isn’t very good,” and the Bio-Slab kit does not help it.

In 1.6 he gives her three options, by situation:

Zimen tested his calculator against the game before trusting it: at 0 stacks, it predicted Bonekrusha would beat a Slab build, and an in-game test on a Potential 5 account agreed. Run across every practical combination, MI Security came out ahead in nearly all of them.

His figure for the gap is 8.9% to 11.4% more damage than Bonekrusha. Qingbo deals less damage than Bonekrusha, but applies to all skills and makes Cryo teams flow better since Arcane and Si arrived.

This site’s Tangtang page currently lists Qingbo as her core set, with MI Security, Bonekrusha and Eternal Xiranite as the other sets. Zimen’s calculator ranks MI Security first for damage; Qingbo is his pick only when smoother rotations matter more than the last 10%.

Can she keep 5 MI Security stacks without crit?

Yes, by Zimen’s test. MI Security only pays at 5 stacks, and each stack needs a critical hit. His answer is her hit count: “TangTang basically uses a sawed-off shotgun, not a hand cannon.” A Waterspout hits 12 times and a full combo makes up to 6 Whirlpools, so even about 10% Critical Rate keeps the stacks, and the set’s own +5% at max stacks makes it steadier.

A food buff makes it nearly permanent: Zimen says the Ginseng dish’s 11% Critical Rate keeps 5 stacks almost all the time.

When should you use the Ultimate Gain build?

When the team needs more Cryo Infliction than damage. Zimen pairs the Eternal Xiranite set with OBJ Velocitous, a 5★ handcannon with Ultimate Gain Efficiency, and brings the ultimate back every three or four battle skills and two combo skills. Because the ultimate also applies Cryo, it feeds the combo loop.

His attribute screen for that build reads Ultimate Gain Efficiency 218.3%, with Agility 387 as the main attribute.

Which weapon and Potential should you get?

By Zimen’s calculation, Brigand’s Calling is about 11% stronger than her battle pass handcannon, and Wedge at its Potential 5 lands close to the battle pass weapon. Signature weapon Potentials add only about 20%, and he says they matter less now that Arcane and Si already apply damage-taken increases. This site lists Brigand’s Calling first and Long Road as the 4★ budget option.

On her own Potentials, his sheet is blunt. Going from P0 to P2 makes her only 7% to 8% stronger as a DPS, and he estimates P2 costs about 240 pulls.

So the right gear, about 10% from MI Security alone, is worth more than two Potentials. The one he does recommend is P1, Reserve Hoard: the combo skill’s multiplier rises to 1.2 times, its cooldown drops by 2 seconds, and each Whirlpool turned into a Waterspout returns 5 more SP. If you have her at P0, he suggests picking up P1 during the rerun. For where she ranks today, see our tier list.
