02New 6-Star Operators: Si & Argent Flow

Si – 6★ Cryo Supporter (until Nov 5)

Greatsword · Intellect / Strength · Signature: Jade Vessel

• Artful Intent: records part of the damage a marked enemy takes, then bursts as Fixed DMG that ignores DEF and RES.
• Inksoul: pulls a decoy out of the marked enemy. Hits on the Inksoul transfer to its host, which helps against fast-moving bosses.
• Cryo or Heat: she applies Heat Infliction if a Heat Operator is in slot 1, and Cryo otherwise.
• Ultimate: gives the whole team Cryo Amp and Heat Amp, and cuts the slot-1 Operator's combo cooldown.

Her Amp does nothing for Physical, Electric or Nature carries. Weapons, gear and rotations are covered in our Si build guide.

Argent Flow – 6★ Electric Guard (from Nov 5)

Sword · Will / Strength · Signature: Lunar Calling · Hongshan Academy of Sciences. Argent Flow (Ye Minghe) charges into battle on his galloper, Nuli.

• Stars Shifted (Combo): applies Electric Infliction and sets up the rotation.
• Bolt Rush (enhanced Battle Skill): a mounted charge that consumes Electric Infliction, forces high-level Electrification and adds Vulnerability.
• Electrification: his version makes enemies take more damage of every type, not only Electric.
• Ultimate: drags weaker enemies along his charge, applies Electric Infliction and Crush, and detonates stacked Sunderization for burst damage.

Best Argent Flow teams

Weapon priority: Lunar Calling > Complexed Industry (free from the Protocol Pass) > Eminent Repute / White Night Nova. Gear: the Pulser Labs set fits well, because his Battle Skill forces Electrification. Pairing with Liino? Read our Liino guide.

Rerun: Tangtang (Oct 29 – Nov 19)

Tangtang, a Cryo Caster, returns on the Ancestral Spring Flows Anew RE-Factor banner, with her Brigand's Calling weapon. She pairs naturally with Si and Yvonne, so Cryo players may want her before Nov 19 — see our Tangtang build guide.

03Version 1.6 Events and Activities

Ending soon: All the Inky Hues and the Umbral Monument limited rewards both close on Nov 5. Clear them before you start pulling on Argent Flow.

04Version 1.6 Free Rewards and Pulls

Each pull costs 500 Oroberyl. 80 pulls guarantee a 6★, but only 120 counted pulls guarantee Argent Flow himself. A similar New Version Guide gift usually appears after the 1.7 preview stream, so check the official channels before Version 1.7 launches.

05Upcoming Operators: Kay & Version 1.7

The Version 1.6 livestream ended with a teaser for Kay, a Rhodes Island Operator who has been searching for the Endministrator. She is expected to guide players through a new area in Version 1.7. Many fans believe Kay is a reconvener of Ceobe, and another silhouette resembles Warfarin. Neither connection, nor Kay's class or banner date, has been officially confirmed.

Version 1.7 has not been dated yet. Based on the current Protocol Pass end date, it is expected around November 25, 2026. That leaves only about three weeks between Argent Flow's arrival and the next new Operator.
