Xiranflow is a late-game three-piece equipment set in Arknights: Endfield built around Arts Reaction consumption, specifically Electrification and Corrosion. It targets Operators who trigger those reactions reliably and want scaling Electric and Nature damage on top of a flat attack boost.
What the Xiranflow set does
The set has a single three-piece bonus. There is no two-piece tier to worry about, so partial equipping does nothing meaningful.
The bonus has two parts working together. The flat part gives the wearer +10% ATK at all times. The conditional part triggers whenever the wearer consumes an Electrification or Corrosion Arts Reaction, granting buff stacks equal to the Status Level of the reaction consumed.
Each stack increases Electric DMG Dealt and Nature DMG Dealt by 15% for 25 seconds. Stacks cap at 3, and each stack's duration is tracked independently, so stacks added later do not extend the duration of earlier ones.
Xiranflow pieces and stats at Lv70
The set occupies three gear slots: Body, Hand, and EDC. Base stats at Lv70 (before Artificing upgrades) are as follows.
| Slot | Main stats | Damage/Efficiency line |
|---|---|---|
| Body | DEF +56, Will +87, Intellect +58 | Cryo & Electric DMG +11.5% |
| Hand | DEF +42, Will +65, Intellect +43 | Cryo & Electric DMG +19.2% |
| EDC | DEF +21, Will +32, Intellect +21 | Normal Skill Efficiency +41.4% |
Artificing is available at Base, +1, +2, and +3 tiers, and it only unlocks on Gold-rarity Tier 4 gear. Substat upgrades from Artificing will only apply once you are already crafting top-tier pieces, so there is no risk of wasting materials on lower-grade gear.
Who benefits most from Xiranflow
The set is built for an Electric-focused carry that consistently sets off and consumes Electrification, with Corrosion as a secondary trigger. Zhuang Fangyi is the clearest fit, and current community builds focus almost entirely on her, including full electric hypercarry setups and late-game F2P-friendly configurations.
Her kit ties into the Novel Xiranite-based Materials Project and the Wuling region's electric-heavy enemy and reaction design, which lines up with what Xiranflow is scaling. Operators without reliable access to Electrification or Corrosion consumption will get very little out of the conditional portion and should look elsewhere.
How the stacking works in practice
Two details matter for uptime. First, the stack count gained per consumption equals the Status Level of the reaction consumed, so stronger reaction applications can push you straight to the 3-stack cap in fewer triggers. Second, each stack's 25-second timer is independent, which means you can refresh individual stacks by triggering additional consumptions during the window rather than being forced to re-stack from zero.
At 3 stacks, the wearer has +45% Electric DMG Dealt and +45% Nature DMG Dealt on top of the baseline +10% ATK. The damage lines on the Body and Hand pieces (+11.5% and +19.2% Cryo & Electric DMG respectively) stack additively into the same Electric damage bucket.
How to get Xiranflow gear
Equipment in Arknights: Endfield is not pulled from a gacha or farmed from Sanity stages. Gear is produced through the Automated Industry Complex (AIC) factory system, which means you craft Xiranflow pieces by setting up production chains that feed the relevant recipes from your regional depot.
Because AIC production runs on its own without spending Sanity, you can AFK-farm Xiranflow pieces once your factory is configured. Stats and substats on crafted gear are fixed per piece rather than randomized at drop, so each completed piece arrives with predictable numbers.
When to skip Xiranflow
If your team does not run an Electric or Nature damage dealer that actively consumes Electrification or Corrosion, the three-piece effect sits largely idle and you are paying for +10% ATK plus two situational damage lines. Operators built around Cryo-only reactions can still use the Body and Hand pieces' Cryo & Electric damage rolls, but the set bonus itself will rarely fire, so a different three-piece set focused on their actual reaction type will outperform it.
For a Zhuang Fangyi carry running Electric hypercarry or reaction-heavy compositions, Xiranflow is the intended late-game set and the pieces are designed around how her damage is meant to scale.
