Kuki Shinobu, The Deputy & The Healer
| Rarity | (4-Star) |
| Element | Electro |
| Weapon | Sword |
| Best Role | Hyperbloom Trigger / Healer |
| Stat Priority | EM > HP% > Healing Bonus |
| Tier | S (In Hyperbloom) |
Kuki Shinobu is the capable Deputy of the Arataki Gang. Initially considered an average healer, the introduction of Dendro catapulted her to top-tier status. Her ability to trigger Hyperbloom reactions from off-field with 100% uptime while consolidating the Healer role makes her one of the most valuable 4-star units in the game.
Pros
- The best Hyperbloom trigger in the game (AoE ring hits seeds easily).
- Consolidates Healing and Damage into one slot.
- Extremely cheap to build (Full EM main stats, no Crit needed).
- 100% Skill uptime (especially at C2).
- Does not require Energy Recharge (Skill-based gameplay).
Cons
- Sacrifices her own HP to heal others (lives in the "Red Zone").
- Healing is lower on Full EM builds compared to HP builds.
- Burst damage is negligible in reaction builds.
- Skill requires close range to hit enemies/seeds.
Quick Guide (TL;DR)
Kuki is built to stack Elemental Mastery (EM) to maximize Hyperbloom damage while providing sufficient healing.
- Best Artifact: 4pc Gilded Dreams or 4pc Flower of Paradise Lost.
- Support Artifact: 4pc Tenacity of the Millelith (If playing pure healer/buffer).
- Best Weapon: Freedom-Sworn (Team Buffs) or Key of Khaj-Nisut (HP->EM Conversion).
- Best 4-Star Weapon: Iron Sting or Toukabou Shigure (Craftable/Event).
- F2P Weapon: Iron Sting (Craftable).
- Main Stats: SANDS: EM | GOBLET: EM | CIRCLET: EM (or Healing Bonus for comfort).
- Talent Priority: Elemental Skill > Elemental Burst > Normal Attack (Ignore).
- Top Team: Alhaitham + Xingqiu + Kuki Shinobu + Nahida (Quickbloom).
Pro Tip: The Suicide Healer: Kuki consumes 30% of her current HP to cast her skill. You want her HP to be below 50% to activate her C6 and A4 passive bonuses, but be careful not to swap her into a heavy hit. Let her ring heal the on-field character, not herself.

Talent Breakdown & Mechanics
Elemental Skill: Sanctifying Ring
- Mechanic: Creates a Grass Ring of Sanctification at the cost of 30% current HP.
- Effect: The ring follows the active character, dealing Electro DMG to nearby enemies and Healing the active character every 1.5s.
- Hyperbloom Trigger: This is the key. The Electro ring has an AoE that hits Dendro Cores on the ground perfectly, triggering Hyperbloom reliably from off-field.
Elemental Burst: Gyoei Narukami Kariyama Rite
- Mechanic: Creates a field of Electro DMG based on Kuki's Max HP.
- Low HP Bonus: If Kuki's HP is below 50% when cast, the field lasts longer.
- Usage: Mostly used for i-frames or breaking Elemental shields. Damage is negligible in EM builds.
A4 Passive: Heart's Repose
- Stat Conversion: Boosts Kuki's ability based on her Elemental Mastery (EM).
- Healing: Healing amount is increased by 75% of EM.
- Damage: Damage is increased by 25% of EM.
- Synergy: This passive allows full EM builds (for Hyperbloom damage) to still heal a respectable amount.
Talent Priority Order:
- Elemental Skill (Level 9+) - For healing and reaction interval.
- Elemental Burst (Level 1-6) - Low priority.
- Normal Attack (Level 1) - Ignore completely.
Stat Requirements & ER Thresholds
Kuki relies mostly on her Skill, which produces particles but doesn't require Energy to function for her primary role.
| Build | Primary Stat | ER Requirement |
|---|---|---|
| Hyperbloom (Recommended) | Elemental Mastery | 0% (Burst Optional) |
| Pure Healer | HP% / Healing Bonus | 0% (Burst Optional) |
Substat Priority:
- Elemental Mastery (Target 900-1000+)
- HP% (For healing comfort)
- Flat HP
- Energy Recharge (Lowest priority)
Best Artifacts Comparison
| Set Name | Role | Reasoning |
|---|---|---|
| 4pc Gilded Dreams | BiS Hyperbloom | Provides massive EM (up to 230) which directly scales Hyperbloom damage. Easy to farm. |
| 4pc Flower of Paradise Lost | BiS Hyperbloom | Mathematically slightly higher damage ceiling than Gilded for reaction damage, but less resin efficient to farm. |
| 4pc Tenacity of the Millelith | Support/Healer | Use this for Aggravate or Physical teams where Kuki acts as a healer/buffer. Skill triggers the ATK buff perfectly. |
Weapon Rankings
| Weapon | Type | Performance | Notes |
|---|---|---|---|
| Freedom-Sworn | EM | S+ | High EM stat and team-wide buffing. Best for increasing team DPS. |
| Key of Khaj-Nisut | HP% | S | Massive HP boost creates huge healing, and passive converts HP to EM for the team. Excellent hybrid option. |
| Iron Sting (R1-R5) | EM | S (F2P) | Craftable. Provides EM. Passive is irrelevant for Hyperbloom but stats are perfect. R1 is enough. |
| Toukabou Shigure | EM | S (Event) | Functionally identical to Iron Sting for Kuki. Use whichever looks better on her. |
Constellation Value
Kuki works at C0, but C2 is a game-changer for rotation smoothness.
- C2: To Forsake Fortune - (100% Uptime) Increases Skill duration by 3s. This makes the duration (15s) match the Cooldown (15s), allowing for zero downtime on healing and application.
- C4: To Sever Sealing - (Extra App) Adds a coordinated Electro hit based on HP. Helps trigger Deepwood Memories or key reactions.
- C6: To Ward Weakness - (Immortality) When Kuki takes lethal damage, she survives with 1 HP (60s CD). Also grants massive EM when HP is low. A "Get out of Jail Free" card.
Top Team Compositions
1. Hyperbloom (The Meta)
- On-Field: Alhaitham / Nahida / Ayato
- Hydro: Xingqiu / Yelan / Furina
- Dendro: Nahida / DMC / Baizhu
- Trigger: Kuki Shinobu
Why it works: Hydro + Dendro creates Bloom seeds. Kuki's Electro ring pulses, hitting the seeds and transforming them into homing Hyperbloom missiles. Kuki builds full EM to maximize this damage.
2. Aggravate/Spread Support
- DPS: Tighnari / Alhaitham / Cyno
- Sub-DPS: Fischl / Yae Miko
- Healer: Kuki Shinobu
- Flex: Kazuha / Zhongli
Why it works: Kuki provides role consolidation (Electro app + Healing) allowing you to run more offensive units like Fischl.
Rotations & Combos
The Simple Cycle:Hydro/Dendro Setup > Kuki E > Main DPS On-Field > Repeat
Tip: If you have C4 Kuki, try to weave in a Normal Attack occasionally to trigger the extra Electro mark, though it's not strictly necessary for Hyperbloom.
Frequently Asked Questions
Why is Kuki's HP always low?
Her skill costs 30% current HP to cast. This is intentional. She performs better at low HP (A4 Passive, C6). Just ensure you have C6 or a shielder if you feel unsafe, or just let her ring heal her up occasionally.
Kuki vs. Raiden for Hyperbloom?
Raiden triggers seeds faster (0.9s vs 1.5s) and at longer range. However, Kuki heals, consolidating the survival slot. Kuki is generally preferred because she frees up the team slots for more offensive units like Nahida/Yelan.
