Neverness To Everness Iroi Build Guide: Best Weapon, Cartridge, Team Comps & Pull Priority
|
Hey Appraisers! With Version 1.2 live, Iroi has finally landed as the second half of the "The Lifeline" banner, and she's shaping up to be one of the best support/healer units NTE has released so far. If you're wondering whether to pull, how to build her, or which team she slots into best, this guide has you covered end to end — kit breakdown, awakening (resonance) priority, ascension mats, BiS Arc, Cartridge, team comps, and pull priority vs Shinku.

Iroi Quick Overview
| Attribute | Details |
|---|---|
| Rarity | S-Class |
| Esper Type | Anima |
| Weapon Type | Liquid |
| Combat Role | Ranged Healer / Buff Support |
| Banner | "The Lifeline" (second half, Version 1.2) |
Iroi is the game's first limited S-Class ranged healer and support character. As an Anima unit, she brings team-wide sustain paired with damage amplification, which makes her a valuable pickup for basically any roster.
Iroi Kit Explained
Basic Attack — Collaboration
Iroi's lambs unleash up to five consecutive Anima DMG attacks while building up "Imagination" on hit. Holding the button charges a follow-up Daydream attack that consumes Imagination to fire up to three additional hits based on charge level, and holding again afterward triggers Lucid Dream, which summons Morpheus for sustained Anima DMG.
Her plunge attack (Wakey-Wakey) deals AoE Anima damage on landing that scales with fall height, up to a 100% bonus, while also building Imagination. She also has a dodge counter, Unconscious Response, which throws Phantasos at the target for Anima DMG, chips away extra Break gauge, and builds Imagination — great for weaving in extra value while dodging mechanics.
Redirect Skill — Future Self Continuity
This is Iroi's bread and butter. Tapping it summons the lambs for an instant team heal and grants allies bonus ATK scaled off Iroi's own ATK, while the lambs themselves keep chipping away at enemies. Holding the skill instead places up to three allies into the Regression state, letting them dodge risky mechanics safely.
Ultimate — Future Self-Continuity Hypothesis
This is where Iroi's identity as a "healer that can also nuke" comes together. If Imagination hasn't reached the threshold, she opens the Dream of the Horned Gate for continuous team healing. Once the threshold is met, she instead opens the Dream of the Ivory Gate, dealing continuous DMG to enemies caught inside and allowing her to revive one Regression-state ally per cast. The dream itself drains Imagination over time and ends once it's depleted, so managing your Imagination economy is key to swapping between pure sustain and burst-revive value on demand.
Tip: Switching into Iroi with a compatible Esper teammate on field triggers her Support Skill (a Morpheus charge attack), and her exploration perk lets her grab bonus loot twice a day from wildlife interactions — don't sleep on that in open-world content.
Iroi Awakening (Resonance) Priority
| Priority | Awakening | Core Effect |
|---|---|---|
| 1 | A2 | Randomly summons Morpheus, Icelus, or Phantasos for a coordinated off-field attack whenever a teammate casts a skill, on a short cooldown |
| 2 | A5 | Adds a bonus effect that increases the whole team's ATK based on Iroi's base ATK, up to a cap |
| 3 | A1 / A4 | A1 boosts Imagination gain efficiency and regenerates Imagination while off-field; A4 increases the ATK Ratio for allies in Regression state |
| 4 | A3 / A6 | A3 boosts healing received by low-HP allies; A6 grants bonus HP and Energy to revived allies |
TL;DR: A2 is the priority breakpoint since it turns Iroi into a passive off-field DPS source, and A5 is your second target for a team-wide ATK boost. Everything past that is a nice-to-have, not a requirement.
Iroi Ascension Materials
Here's what you'll need to fully level and unlock Iroi's full kit day one:
- Fading Silhouette ×57
- Blurred Silhouette ×58
- Chaos Silhouette ×79
- Dreamless Seed ×96
- A Page from Delusion's Shore ×86
- White Rose ×65
- Good Boy Stamp ×35
- Beetle Coin ×2,783,000
- Fons ×38,400
Start farming Silhouettes and Dreamless Seeds early — these tend to be the bottleneck for most limited units, and you don't want to be short right before her banner ends.
Best Weapon (Arc) for Iroi
BiS — Iroi's Signature Arc: The Wrong Gate
Her signature weapon is comfortably the best option if you can afford it. It boosts ATK by 16%, and whenever the wearer heals allies, it grants self Anima DMG +30% along with a 15% universal DMG bonus for the whole team for 20 seconds, refreshing on every new trigger — a unique team-wide buff that no other Arc currently replicates.
Other Solid Picks
If you're F2P or can't secure her signature, these are viable substitutes depending on what your team needs:
Output-focused:
- Fluff of Fleetness — grants 5% ATK per second while on-field, stacking up to 5 times, resetting on switch-out.
- Clear Skies — boosts Anima DMG from Redirect Skill and Ultimate by 20%.
Utility-focused:
- Mind Royale — grants 10 Ultimate Energy on Redirect Skill cast, with a 20s internal cooldown.
- Call of the Twisted City — increases Healing Bonus by 12% for 10 seconds after a Redirect Skill cast (does not stack).
Best Cartridge for Iroi: Speedy Hedgehog
Speedy Hedgehog is Iroi's undisputed best-in-slot Cartridge. It significantly improves her Energy generation and provides a team-wide ATK buff after she uses her Ultimate — a near-perfect match for a unit whose whole job is keeping the team alive while amping their damage.
Mainstat priority: HP Bonus > Healing Bonus > Cycle Intensity > Anima DMG Bonus
Substat priority: HP Bonus > Flat HP > Cycle Intensity > CRIT Rate
Since Iroi's healing and support mechanics scale heavily off her max HP, resist the urge to chase CRIT or ATK substats here — HP is genuinely her best stat across the board.
Best Team Comps for Iroi
1. Lakshana Overflow Burst Team (Meta / Full Build)
| Lakshana Overflow Burst Team | |||
 Shinku |  Hathor |  Esper Zero |  Iroi |
This lineup pairs Iroi with Shinku to build a highly durable hypercarry setup focused on stable field presence and sustained damage. Iroi's job here is simple: keep Shinku alive through her setup phase and create a safer window for her burst damage.
2. Full Blossom Endgame Build
| Full Blossom Endgame Build | |||
 Nanally | Esper Zero |  Jiuyuan | Iroi |
Iroi's passive duplicates Vita Buds to extend Blossom duration, patching the classic Blossom-team weakness of lacking damage buffs and healing. Steady cycle value from her lambs also makes it easy to stack maximum Blossom layers.
3. F2P / Low-Rarity Variant (No Nanally)
| F2P Low-Rarity Variant | |||
 Chiz | Jiuyuan |  Mint | Iroi |
Great for accounts missing Shinku or a 5-star Nanally. Chiz generates cycle value frequently, Jiuyuan groups enemies, and Mint handles element matching and energy recovery — a fully A-tier squad that still clears overworld content smoothly.
Pull Priority: Iroi vs. Shinku
Iroi is featured on "The Lifeline" banner, and deciding between her and Shinku really comes down to what your account is missing:
| Player Needs | Priority Choice | Reasoning |
|---|---|---|
| Missing a strong main DPS | Shinku | Directly supplements front-line output — ideal if you need immediate damage |
| Already have a mature main DPS | Iroi | Healing and buffs integrate easily into existing rosters and offer a longer usage cycle |
| Cosmos-focused account | Shinku | Likely the new Cosmos core going forward |
| Need survival/utility | Iroi | Combines healing and damage amplification, saving a dedicated roster slot |
F2P budget tip: hard pity sits at 90 pulls (14,400 Annulith) for a guaranteed copy. If your budget is tight, secure Iroi's base kit first — her signature Arc Wrong Door is a strong upgrade thanks to its team-wide 15% DMG buff, but it's not mandatory to make her function.
FAQ
Is Iroi worth pulling in NTE?
Yes, if your account lacks a reliable healer or survival unit, or if you want one character slot to cover both healing and team-wide DMG buffs. Her Ultimate's dual healing/burst modes also give her flexibility across most content types.
What is Iroi's best weapon (Arc)?
Her signature Arc, The Wrong Gate, is BiS thanks to its 16% ATK boost and team-wide 15% DMG bonus on heal. If you don't pull her signature, Fluff of Fleetness or Mind Royale are solid substitutes depending on whether you want more output or more Energy generation.
What's the best Cartridge for Iroi?
Speedy Hedgehog is her best-in-slot Cartridge, boosting Energy generation and granting a team ATK buff after her Ultimate. Prioritize HP Bonus and Healing Bonus on the main stats.
Should I pull Iroi or Shinku first?
If you're missing a main damage dealer, prioritize Shinku. If you already have a solid main DPS and need more survivability or team-wide buffs, pull Iroi first — she has a longer usage cycle and fits into almost any team.
How many pulls do I need to guarantee Iroi?
90 pulls (14,400 Annulith) guarantee her at hard pity. Prioritize securing her base copy before saving for her signature weapon.
Does Iroi work well with Shinku?
Yes — Iroi keeps Shinku alive during her setup phase and creates a safer window for Shinku's burst damage, making the two a strong pairing for hypercarry-style teams.
NTE: Neverness to Everness
Conclusion
Iroi is easily one of the strongest support releases NTE has had, offering a rare mix of team-wide healing, DMG amplification, and even off-field revives once you build around her Imagination economy. If your roster is missing a reliable survival unit — or you just want to free up a slot currently taken by a pure healer — she's a safe, high-value pull. Prioritize her base kit first, chase her signature Arc if budget allows, and pair her with Speedy Hedgehog for the smoothest experience.
