Best Luna build in The First Descendant: Skills, Weapons, Reactor & Modules

Luna is a powerful support character in The First Descendant who can disrupt enemies and inflict heavy damage from a distance. Here’s the best Luna build you can use with the right skills, weapons, modules, and more.

The first significant update for The First Descendant introduced Luna, a worthy support member to the existing roster. Her musical rhythms and special weapons allow her to deal some serious damage to her enemies.

However, to fit the melody of the perils she may face in the game, you’ll need the best build available to turn her into a lethal Descendant. While she is in the B-tier on our tier list, she is still worth playing if you use the correct skills, reactors, weapons, and modules.

Here’s what you need to know in order to get the most out of Luna in The First Descendant.

The First Descendant Best Luna Build – Recommended

Best Luna skills

As is the case with all Descendants, Luna has access to five skills in The First Descendant. If used correctly, they all can be quite lethal. However, they need to be used tactically since your MP is limited.

So, here are the two abilities we’d recommend you use:

1. Stage Presence is the best skill of all that you can activate with Luna. This gives her access to a special weapon, where performing the notes in time to the music by using skills or hitting monsters stacks, and increases her Skill Power Modifier. Her primary strength stems from non-weapon-based talents and buffs.
2. Relaxing Act is one of the other skills which is the best to use with Luna. However, this purely focuses on Luna’s healing and support capabilities where, when she hits an enemy with a note, it grants an effect that instantly recovers the MP of Luna and her allies. This can be best used during a Void Intercept battle where your teammates are all DPS characters and need a trusty healer on their side.

All Luna skills

Below are the five available skills for Luna in The First Descendant:

• Improvisation (Passive): Using any skill increases Inspiration Gauge, which lets Luna use Enhanced Skills.
• Stage Presence: Using the skill changes Luna’s weapon to her Unique Weapon. Performing the notes in time to the music by using skills or hitting monsters stacks and increases her Skill Power Modifier.
• Passionate Stage: Using this skill makes Luna play upbeat music, increasing the Skill Power Modifier of Luna and her allies. Gaining the Enhanced Effect increases the Skill Power Modifier even more, and it also increases the Skill Critical Hit Rate and damage of allies.
• Relaxing Act: Using the skill makes Luna play relaxing music. Hitting the enemy with a note grants an effect that instantly recovers the MP of Luna and her allies. Gaining the Enhanced Effect increases MP Recovery and reduces Skill Cost.
• Delightful Stage: Using the skill makes Luna play delightful music. Hitting the enemy with a note increases Inspiration Gauge and decreases the skill cooldown of allies. Gaining the Enhanced Effect increases the Inspiration Gauge even more and immediately resets the cooldown of allies.

Best weapons for Luna

The best weapons for Luna are a combination of:

• Thunder Cage – Submachine Gun
• Afterglow Sword – Sniper Rifle
• Nazeistra’s Devotion – Hand Cannon

The Thunder Cage SMG boasts a high firing rate and an overcharge boost that, when you defeat an enemy, causes them to release an electric shockwave. This shockwave deals Electric ATK damage to nearby foes within 3 meters. 

As a result, Thunder Cage allows you to deal AoE damage without using any abilities, allowing Luna to focus on healing allies with her abilities rather than having to clear mobs.

Since most of Luna’s skills are dependent on long-range attacks, the Afterglow Sword makes an ideal match for her arsenal. With it, she can hit enemy weak points from a distance and inflict Death Propagation, which can prove useful while you’re supporting your teammates.

Finally, Nazeistra’s Devotion is an excellent secondary weapon for Luna in The First Descendant. This Hand Cannon packs a powerful punch and reduces the enemy’s protection by 30% for three seconds, significantly improving your critical hit probability via the Passionate Stage skill and allowing you to eliminate enemies with ease.

Best Reactor

Materialized Mechanics Reactor is the best Luna reactor in The First Descendant. Skill Range and Skill Duration are the best sub-stats for your position.

They will allow you to support your teammates from a distance and for an extended period of time. During the early game, equip the rarest one available, however as you progress, equip the Ultimate version.

However, we’ve got a couple more reactors for you to use with Luna to maximize her output:

1. Optimization Condition: Thunder Cage
2. Skill Power Boost Ratio
   Materialized Mechanic: Boost to Non-Attribute and Tech type
3. Bonus Conditions: Non-attribute power boost ratio and Skill critical hit rate

Remember to place the mods in the appropriate socket based on their module type and class. This drastically reduces the Module Capacity Cost, allowing you to quickly install strong and pricey modifications.

You may also employ Crystallization Catalysts to add Module Sockets to your loadout, allowing you to maximize efficiency and begin optimizing for a build that includes all of the necessary modules.

Best External Components for Luna

In Luna’s build, the best External Components are those with stats like Max Shield, Max HP, HP Recovery, and DEF.

Getting the appropriate components comes down to luck. Because the First Descendant is a looter shooter, you will need to spend time looking for External Components with high stats.
