The First Descendant Luna build, loadout, and gameplay guide

As The First Descendant's first post-release character, many are wondering what an optimized Luna build should entail. Broadly speaking, Luna is a support class through and through. You could try using the Noise Surge skill module to pump some DPS into her, but in our testing, this is not good enough to warrant a DPS-centric build.

In this Luna build guide, we'll explain the intended way to play this character in The First Descendant. We will go over Luna's abilities, how to get the most out of them through a module setup, as well as other loadout elements to think about.

How to play Luna in The First Descendant

Here's a detailed breakdown of what each of Luna's abilities do in The First Descendant:

Ability Name	Ability Type	Ability Details	Additional Buffs	MP Cost	Cooldown
Stage Presence	Non-Attribute, Tech	Equip Luna's signature weapon, which enables ability use. Failing to hit the notes with your shots will decrease MP. Activating an ability during a note's timing will recover 10x bullets. The skill runs out when you run out of MP or bullets.	Hitting the notes with this weapon casts Perfect Pitch, which is a stacking Skill Power Modifier buff that maxes out at 25%. Note that only Luna gains this buff, not her allies.	15	8 seconds
Exciting Act	Non-Attribute, Singular	Grants Exciting Performance, increasing Skill Power Modifier for 14.5 seconds.	Grants Exciting Sound to allies, which increases their Skill Power by a factor of your Max MP. The enhanced version also grants Skill Crit Hit Rate and Skill Crit Hit Damage.	20	6 seconds if you hit the Note, 15 seconds if you fail
Relaxing Act	Non-Attribute, Singular	Grants Relaxing Performance, which gradually recovers MP.	Grants Relaxing Sound to allies, which recovers their MP. The enhanced version additionally decreases their custom resource cost for skills.	15	7 seconds if you hit the Note, 20 seconds if you fail
Cheerful Act	Non-Attribute, Singular	Change notes to Cheerful Act, increasing the Inspiration Gauge meter if you hit the notes with this ability.	Grants Cheerful Sound to allies within range, granting -10% Skill Cooldown. The enhanced version of Cheerful Sound resets their skill cooldown outright.	30	45 seconds if you hit the Note, 80 seconds if you fail

Passive: Inspiration Gauge

A big part of Luna's kit is 'Enhanced Abilities' which depend on the state of the 'Inspiration Gauge', her custom resource meter. The Inspiration Gauge fills up when you hit your signature weapon shots or abilities on-Note, and decreases when you fail to do so. A full Inspiration Gauge, in turn, lets you hit an 'Enhanced Ability' version of your Skills, which consumes it fully in the process.

Best Skill rotation for Luna

The Skill rotation for Luna depends on your situation and what you want to achieve in terms of group support. However, in general, it should go something like First Ability > Fourth Ability on-Note till you fill-up the Inspiration Gauge > Enhanced 2/3/4. Here's a more detailed explanation:

You will have to cast your Stage Presence (Q, first ability) to pull out the synth gun to use any of her other abilities, so this is a non-negotiable part of the rotation.
Use your Cheerful Act (Z, fourth ability) to fill up your custom resource bar fast. Enhanced abilities are much more powerful, and you want to use them as much as possible.
Once the bar is full, use the enhanced ability that you'd like. In the vast majority of cases, Enhanced Cheerful Sound is the strongest support skill from Luna. Coordinate with your team to execute it right after an ally has used their high-cooldown Ult.
Note that the custom bar depletes automatically after a while if you're out of combat, so no point trying to build it up before combat starts.

If you don't have this character yet, here's how to get Luna in The First Descendant.

Best Module setup for Luna in The First Descendant

The intended way to build Luna is propping up her support stats. For this reason, the first stat to pad out is Skill Range. Afterwards, you can spec into defensive stats and higher MP. Here's what a full support build would look like:

Nimble Footsteps (red mod)
Sub-attack/Grappling hook mod
Maximize Range
Skill Expansion
Increased HP
Arche Concretion
Agony/MP Accelerant
Enlightenment

DPS Build with Noise Surge

If you manage to get Luna's Noise Surge module, she can be a nuke-spaming Descendant. The following is the module priority for a DPS build:

Noise Surge (red mod)
Sub-attack/Grappling Hook mod
Increase HP
Skill Expansion
Maximize Skill
Maximize Power
crit mods

All the critical mods (Emergency Measures, Front Lines, and so on) have a triangle (Almandine) socket type, meaning you need to make a dedicated DPS mod loadout with additional loadout-specific socket assignment. In other words, Luna would take many more Crystallization Catalysts than a regular character to spec into diverse playstyles.

Best Reactor for Luna in The First Descendant

The best Reactor for a Luna build in The First Descendant will be a Materialized Singularity Reactor of Rare or Legendary rarity. This will be the best value for her second, third, and fourth skills. Since you'll have your Synth gun out at all times, we also recommend going for a purple Reactor over a golden one.

The ideal bonus stat rolls will vary depending on what kind of Luna build you want:

DPS build: Skill Crit Hit Rate, Skill Crit Hit Damage, Non-Attribute Damage bonus
Support build: Skill Range, Skill Cooldown reduction, Skill Duration

Best Weapon for Luna in The First Descendant

Luna generally has the Synth gun out at all times, which makes your actual weapon choice less important. However, if you want to lean into the 'support' gimmick, Naziestra's Devotion is the best 'off-hand' gun for Luna due to its DEF-shredding unique trait.

Best External Components for Luna in The First Descendant

The External Components will depend on the totality of your build, and what stat it lacks. Generally, going for a combination of DEF and max MP is the best. Specifically, Luna benefits from the Bravery set, which drops from the Obstructor boss in The First Descendant.
