Iroi Complete Build Guide: 1.2 Second-Half Limited S-Rank Anima Universal Support, Regression + Imagination Mechanics, Ultimate Revives Teammates

Key Answer: Iroi (from the Greek dream gods Oneiroi) is the limited S-rank from the 1.2 second-half banner (expected 7/29). Her element is Anima, her Arc type is Liquid, and she is a CSU Containment & Strike Unit Assault Squad Two member. Her role is Universal Support (healing + Crit DMG buff + shield + reviving teammates). Core loop: basic attacks accumulate “Imagination” → hold skill to put teammates into “Regression” to assist → the Ultimate “3.8-Billion-Year Mirage” opens dreamscapes based on Imagination, with the Ivory Gate able to revive one teammate. Her best partner is Shinku (1.2’s strongest combo). Signature Arc: The Wrong Gate; Gear set: Street Brawler. LDShop rates her a “top-tier must-pull,” but the E0-vs-high-E gap is large.

⏳ Not yet live: Iroi is expected to release on 2026/7/29 (1.2 second-half banner). The skills / mechanics / build info below is compiled from the 1.2 livestream + datamining (Icy Veins, LDShop, Mobalytics, etc.); exact values and the official TW translations are subject to the in-game text after release.

“Let her and her little sheep carry the burden for you — you just focus on dealing damage” — the Anima limited Support of 1.2’s second half, fighting alongside three dream sheep, and one of the few NTE characters who can Revive teammates.

3. Skill Set

Core loop: basic attacks accumulate Imagination → hold skill to put teammates into Regression to assist → Ultimate opens a dreamscape (the Ivory Gate can revive a teammate).

Basic Attack [Collaboration]

• Commands the little sheep in up to a 5-hit combo dealing Anima damage; hits accumulate “Imagination.”
• Multipliers: 1st 69.4% / 2nd 39.2%×3 / 3rd 20.8%×8 / 4th 158.1% / 5th 38.8%×3.

Charged Attack [Daydream] ⭐

• Hold basic attack to consume Imagination and charge, releasing up to 3 tiers based on charge level.
• Afterward, holding again can fire “Lucid Dream” — summons Morpheus for continuous fire (Anima damage).

Aerial Attack [Wakey-Wakey]

• Tap attack while airborne for a plunge; on landing deals area Anima damage (up to +100% by height); hits accumulate Imagination.

Dodge Skill (Tap) [Self-Identity Extension]

• Summons the little sheep to heal the whole team once, and grants Bonus ATK based on her own ATK (ratio 15%, healing ratio 147%).
• The little sheep attack independently and group nearby enemies; each Regressed teammate deals extra damage.

Dodge Skill (Hold) [Future Self Continuity] ⭐

• Creates a dream illusion that puts 3 teammates into the “Regression” state to assist in attacking (auto-removed when leaving combat).
• While Iroi is on field and in combat, fallen teammates automatically enter the Regression state (setting up the revive).

Ultimate Finisher [3.8-Billion-Year Mirage] ⭐⭐⭐

Returns to the primordial dream and opens the gates of dreams, triggering different effects based on Imagination:

• Below threshold → Dream of the Horned Gate: continuous team-wide healing (cast healing 183.8% / sustained healing 58.8% × 8 seconds).
• At threshold → Dream of the Ivory Gate: continuously damages enemies in the dream (cast 799.6% / DoT 115.9%); at this point, hold a Regressed character’s portrait to Revive that character and restore some HP (up to 1 revive per Ultimate).
• The dreamscape continuously consumes Imagination and ends when depleted; revived characters return to the Regression state.
• During the Ultimate, Imagination cannot be accumulated, but Daydream and Lucid Dream do not consume Imagination.

Assist Skill [Just in Time!]

• Picks up Morpheus and strikes forward once (Anima damage 539.7%), heals the whole team, and accumulates Imagination.

Passive 1 [Mirror Image]

• Blossom enhancement — when the current Vita Bud disappears, spawns a clone (the clone cannot regenerate).

Passive 2 [Sympathetic Nerves] ⭐

• When healing teammates, briefly grants the whole team extra Defense-ignore — letting her boost team-wide output while healing.

Field Skills

• 95-Million-Year Fission: in the open world, interact with small animals to obtain random growth materials (up to 3 times per day, total cap 999 times).
• Ride-Along Chat: each Swift Travel order grants an extra 1000 Fons; each passenger’s satisfaction cap +25.

4. Eidolons / Awakenings

Awakening	Name	Effect	Priority
A1	Iterated Prisoner’s Dilemma	While Iroi is off-field, Imagination slowly regenerates (off-field energy recovery)	⭐⭐⭐⭐
A2	(provisional)	When any teammate casts a skill, randomly summons a little sheep to assist (with cooldown)	⭐⭐⭐
A3	(provisional)	For teammates below a specific HP percentage, increases the healing they receive	⭐⭐⭐
A4	(provisional)	Boosts the ATK multiplier of Regressed teammates (Morpheus / Icelos / Phantasos each gain +ATK multiplier)	⭐⭐⭐⭐
A5	(provisional)	Enhances Sympathetic Nerves: additionally boosts team-wide ATK (based on Iroi’s Base ATK), and increases healing received for low-HP teammates	⭐⭐⭐
A6	(provisional)	After casting the Ultimate, revived characters restore extra HP, Cycle Energy, and Ultimate Energy	⭐⭐⭐⭐⭐

Resonance Nodes

• E3: Collaboration, Future Self Continuity, and 3.8-Billion-Year Mirage skill levels +1.
• E6: boosts team-wide Crit DMG; Iroi deals extra damage for each Regressed teammate.

Awakening names are provisional (English source Icy Veins); exact values and the official TW translations are subject to the in-game text. She works as a Support at E0, but the E0-vs-E2 / E6 gap is large — the investment cost-effectiveness should be weighed.

5. Best Build

⭐ Signature Arc: The Wrong Gate

• An S-rank Liquid Arc, Iroi’s signature.
• Base ATK 570 / ATK 30%.
• Core effect: ATK +32%; on healing trigger: the wielder’s Anima damage +60% (20 seconds), and all other team members gain +30% all-damage bonus (unique effect, does not stack).
• (Values compiled from LDShop / Mobalytics, subject to in-game.)

Alternative Arcs

1. The Wrong Gate (signature) — the graduation top pick (+30% team-wide all damage)
2. Call of the Twisted City — best F2P pick (Mobalytics-recommended)
3. Fluff of Fleetness — Battle Pass Arc (ATK 512 / Crit DMG 44%; +9% ATK per second on field, up to 5 stacks)

Gear Set (Cartridge) Recommendations

1. Street Brawler ⭐:
   • 2-piece: Lakshana damage +10%
   • 4-piece: Crit Rate +14%; when the team triggers Remora or Stain, the bonus rises to 14% (20 seconds)
2. Prioritize Energy Recharge (to keep a high Ultimate frequency) > Healing Bonus > HP%

Main / Sub Stats

Slot	Direction
Main Stat	Energy Recharge > Healing Bonus > HP%
Sub Stats	Effect Hit Rate > ATK% > DEF%
Build Direction	Mainly stack HP (healing / shield / revive scaling rise with HP), secondarily Healing % and Cooldown Reduction

6. Recommended Teams

⭐ Shinku Team (1.2 Abyss best solution)

Shinku (Main DPS) + Iroi (Support) + Hathor (Remora) + Jiuyuan (Anima Sub DPS)

• Iroi provides Crit DMG buffs + team-wide healing + elemental reaction amplification, doubling Shinku’s damage during the Surging Crimson phase
• Hathor extends Remora to 12 seconds and grants +10% team-wide Crit Rate
• Jiuyuan speeds up Ultimate rotation, forming the “Shinku + Iroi” dual-support synergy
• Once Iroi goes live in the 1.2 second half, this is the expected strongest burst combo

High-Difficulty Boss Team

Chaos / Nanally (Main DPS) + Iroi + Hathor + Mint

• Iroi provides team-wide damage boosts + energy recovery, speeding up the Main DPS’s stacking and burst
• Hathor applies Remora; Mint fills in damage

F2P General Team

Any Main DPS + Iroi + Jiuyuan + Protagonist Zero

• Iroi’s versatility (healing + damage boost + revive) lets her fit Cosmos / Anima / Lakshana Main DPS of any element

Iroi is a Universal Support who fits into almost any team; her greatest value is the revive + sustain capacity in high-difficulty Abyss.

7. Should You Pull?

1. Clear role: an Anima Universal Support (healing + Crit DMG + shield + revive — four-in-one), a rare multi-function support in NTE
2. Strong scenarios: the revive + sustain in high-difficulty Abyss is almost irreplaceable; pairing with Shinku is 1.2’s strongest combo
3. Eidolon investment: works as a Support at E0, but the E0-vs-E2 / E6 gap is large — some CN players feel the full payoff needs E2 to shine, so the investment cost-effectiveness should be weighed
4. Recommended for: players who already have Shinku (want the strongest burst team), those lacking a top-tier support, and frequent high-difficulty Abyss players
5. Can wait if: you already have a complete support lineup, want to graduate a support at E0 only (may feel insufficient), or rarely run high-difficulty content
6. Verdict: LDShop rates her a “top-tier must-pull support,” but it’s best to plan at least to E2 before pouring in heavy resources; pulling only E0 is workable, just with a lower ceiling

8. Name Origin / Story

• Iroi comes from the Greek myth of the “dream gods Oneiroi (Ὄνειροι)” — the deities governing dreams (singular Oneiros), sons of the sleep god Hypnos; directly echoing her skills (Daydream, Lucid Dream, the 3.8-Billion-Year Mirage)
• She fuses dual demon and angel elements, hinting at a dual personality or dual-form combat style
• Quiet, reserved, and acutely empathetic — her inner softness is directly reflected in her healing / support-oriented skill design
• Her affiliation is CSU (Containment & Strike Unit) Assault Squad Two, the same unit as Shinku
