Iuno’s Basic Attack – Moonring & Moonbow

Iuno uses a lunar ring for her Basic Attacks, so we can call this “Ring Attack”. It deals standard Basic Attack damage.

However, Iuno has another type of Basic Attack where she unfolds the lunar ring into a lunar bow to attack. We can call this “Bow Attack”. It also has three segments, but with higher multipliers, and it deals Resonance Liberation damage, which is core to Iuno’s kit.

It’s worth noting that Iuno does not have a Heavy Attack. If you hold down the Basic Attack key, Iuno will automatically perform continuous Ring Attacks or Bow Attacks.

So, how do you trigger the Bow Attack?
When performing the third segment of a Basic Attack, using an Intro Skill, or using a Resonance Skill, the Resonance Skill icon—a white horizontal ring—will glow and transform into a tilted, downward-plunging ring.

This is the Closing Refrain mentioned in the skill description. We can refer to it as the Enhanced Resonance Skill.

When you press this Enhanced Resonance Skill, Iuno performs a leg lift followed by a downward strike. You’ll then see a blue glow on the ground, a giant moon appearing in the sky, and the Forte Circuit bar turning blue. A countdown buff will also appear, and Iuno will gain a new jump skill icon. This indicates that Iuno has entered the Lunar Cycle state.

In the Lunar Cycle state, Iuno’s movement mode changes to flight. Although she can only move horizontally, there are no height restrictions, and she can continue flying even without stamina.

Enhanced Status – Lunar Cycle

In combat, the Lunar Cycle state is divided into two phases: Half Moon and New Moon. When entering the enhanced state through any method, you will first default to the Half Moon state.

In the Half Moon state, Basic Attacks remain Ring Attacks, with the same damage multipliers, animations, and speed as the normal state. However, in this state, Ring Attacks restore the Forte Circuit bar when they hit enemies.

The Resonance Skill icon in the Half Moon state changes again, becoming a vertical ring. This is the Unfinished Refrain mentioned in the skill description. It shares a cooldown with the Closing Refrain and has identical damage, animations, and effects—essentially the same skill. There is no need to distinguish between the two.

There will be a leftmost icon , which corresponds to the jump skill. This is the Heavy Attack – Flux: Moonring mentioned in the skill description.

In the Half Moon state, the icon shows three arrows. If your Forte Circuit Energy is full, the icon will glow, but this does not affect its damage. The glow simply reminds you to switch to the New Moon state.

When you press the jump key, Iuno dashes downward but reappears in the air. The Half Moon in the sky transforms into a New Moon, and the lunar ring at Iuno’s feet unfolds into a lunar bow. The previously calm blue energy on the Forte Circuit bar begins to fluctuate, and the central icon changes into a bow shape. This is why we can also call this the “Bow State.”

In this state, Iuno’s Basic Attacks become Bow Attacks. If you have Forte Circuit Energy, Bow Attacks will consume it to increase damage multipliers and gain additional Concerto Energy. The three segments of Bow Attacks consume 10/15/25 Forte Circuit Energy, respectively. If you run out of energy, the damage remains unaffected as long as some energy is consumed. For example, if only 10 Energy remains during the third Bow Attack segment, consuming 10 Energy will yield the same damage as consuming 25.

The same logic applies to the Resonance Skill. In the New Moon (or Bow) state, Iuno’s Resonance Skill becomes a charge-based skill like Changli’s or Chixia’s, recharging every 10 seconds with a maximum of 2 charges. This is the Arc Beyond the Edge mentioned in the skill description. We can simply call it “Arrow Shot.”

You can use this skill even without Forte Circuit Energy, but consuming Forte Circuit Energy significantly increases its damage and grants additional Concerto Energy. Additionally, this skill has a unique feature: you can input a direction key while shooting to dash in that direction. It can also be used while being hit to break out of the hitstun state.

The  jump skill can be used to switch back to the Half Moon state, though this is generally unnecessary.

Special Heavy Attack – Absolute Fullness

Once you’ve used up all the Circuit Energy, your Concerto Energy will usually be full. At full Concerto Energy, Iuno can perform a special Heavy Attack: Absolute Fullness. Hold down the Basic Attack key, and Iuno will deploy a Fullmoon Domain.

This domain lasts for a fixed 30 seconds and will not end early even if Iuno leaves the field. It has two effects:

Heals HP and restores stamina every 5 seconds.
When the active character in the domain gains a shield, they receive a stack of Wan Light. Each stack provides 4% universal DMG Deepen, up to 10 stacks (40% total). However, like most Outro Skill’s effects, if you switch characters, all Wan Light stacks will disappear.
Note: Iuno cannot provide shields to other characters, so the full benefit of Wan Light can only be utilized by characters who can frequently gain shields themselves, such as Augusta.

However, Iuno’s Outro effect offers a small compensation: it provides 50% Heavy Attack DMG Deepen for 14 seconds. This makes Iuno a viable replacement for Mortefi in Jiyan teams, aside from her synergy with Augusta.

Resonance Liberation & Inherent Skills

The Resonance Liberation is straightforward: it deals damage and enters the Half Moon state. It can be cast in mid-air without height restrictions.

Inherent Skill 1 allows Iuno to frequently gain shields.
Inherent Skill 2 grants Iuno 5 stacks of Wan Light each when using an Intro Skill or Resonance Liberation. Since Iuno’s rotations are short, there is little time to slowly stack Wan Light otherwise.
