Mid-Air Maneuvering and MP Collector are considered the top Luna modules in The First Descendant. Mid-Air Maneuvering provides outstanding survivability and mobility, which is invaluable when you’re playing as a Support character. It allows you to attach your Grapple Hook even in mid-air, giving you unmatched positioning control.
Meanwhile, MP Collector is an essential tool for MP regeneration. This module ensures you can consistently cast abilities, keeping your allies buffed as often as they need. For a Support character like Luna, this is indispensable.
Here is a full breakdown of the best mods for Luna in TFD:
As mentioned in this The First Descendant best Luna build, we suggest focusing on fewer modules but enhancing them to their maximum level. This compensates for the missing slots and strengthens Luna overall.
| Slot | Module | Rarity |
|---|---|---|
| 1 (Skill Module) | Empty | N/A |
| 2 | Increased HP | Normal |
| 3 | Increased DEF | Normal |
| 4 | MP Collector | Ultimate |
| 5 | Skill Extension | Normal |
| 6 | Skill Expansion | Normal |
| 7 (Sub Module) | Mid-Air Maneuvering | Ultimate |
| 8 | Empty | N/A |
| 9 | Empty | N/A |
| 10 | Empty | N/A |
| 11 | Technician | Normal |
| 12 | Medical Support | Normal |
We recommend upgrading Luna modules in this order of priority:
With these modules equipped, Luna can thrive in dungeon runs and party boss battles. As a Support Descendant, your main goal is to keep your teammates alive while maintaining your own survivability. That’s why Increased HP and DEF are prioritized early in your setup.

The Thunder Cage SMG is by far the best weapon for Luna in The First Descendant. When you take down an enemy, it releases an Electric Shockwave that damages surrounding foes. Paired with the MP Collector mod, it enables you to recover MP frequently without even thinking about it.
Having a fast-firing, high DPS weapon is vital for our Luna build. Although she is a Support, Luna must be able to hold her ground and defend her allies in close combat encounters.
Recommended mods for the Thunder Cage while playing Luna include:
While you may use another SMG temporarily, obtaining Thunder Cage should be a top priority because of its unique effect.
The Materialized Mechanics Reactor is the best choice for Luna in The First Descendant. Skill Range and Skill Duration are the most useful sub-stats for her supportive role, allowing you to strengthen your allies from further away and for longer periods. Use the highest rarity version available early on, and upgrade to the Ultimate version later.
Here’s a quick overview of what reactors do in TFD:
Reactors are powerful upgrades that boost your abilities, stats, and overall efficiency. They define the base power of your skills and melee attacks and are designed to match specific skill types, maximizing effectiveness when properly aligned. Choosing the right reactor is key to excelling in high-difficulty content and achieving the most out of your build.
External components are random drops that come with a random stat and traits. Since they cannot be upgraded and are locked to RNG at max level, they serve as the final polish for your Luna build. Here are the best external components to look for:
Together, these items form the Tomb Vanguard Set, which significantly enhances defense, improves ally buffs, and boosts Skill Power. Over time, you’ll gather many external components, but focus on evaluating them for these stats to ensure they’re worth keeping:
These attributes increase survivability during late-game scenarios and should always be prioritized for Luna’s role.
Luna can be unlocked by either purchasing her from the in-game shop or researching her. Researching requires the following items:

Luna has five unique abilities that help allies and control the battlefield. Below is a placeholder for the detailed skill descriptions:
| Skill | Description |
|---|---|
| Stage Presence | Luna switches to her unique weapon, and by timing her skills or attacking enemies in rhythm with the music, she builds stacks that boost her Skill Power Modifier. |
| Passionate Stage | Luna performs energetic music, boosting the Skill Power Modifier for herself and her allies. When the Enhanced Effect is activated, it further increases the Skill Power Modifier while also raising the Skill Critical Hit Rate and damage for her allies. |
| Relaxing Act | Luna plays soothing music, and hitting an enemy with a note instantly restores MP for herself and her allies. When the Enhanced Effect is triggered, MP restoration is further increased, and skill costs are reduced. |
| Delightful Stage | Luna plays cheerful music, and hitting an enemy with a note boosts the Inspiration Gauge and reduces the skill cooldown for allies. With the Enhanced Effect, the Inspiration Gauge is increased even further, and allies' cooldowns are instantly reset. |
| Improvisation | Using any skill increases Luna's Inspiration Gauge, enabling her to unleash Enhanced Skills. This is a passive skill in her arsenal. |
Most of her skills, aside from Stage Presence, are focused on buffing teammates and enhancing their combat effectiveness. This makes Luna an excellent Support option, providing everything from MP restoration to boosting Skill Critical Hit Rate.

As we learn more about her mechanics and strategies, we will update this section with in-depth gameplay advice. Keep an eye out for updates to stay ahead with the best ways to master Luna.
The strongest Luna build relies on the Thunder Cage SMG combined with the Mid-Air Maneuvering and MP Collector modules. This setup gives you reliable damage output while keeping your team supported at all times.
The most valuable components to prioritize for Luna are Max Shields, HP Recovery, Max HP, and DEF, as they maximize her endurance and ability to stay alive during end-game fights.
Luna performs best with the Thunder Cage SMG. It offers strong damage in close-range battles and releases Electric Shockwaves on fallen enemies, giving her extra AoE impact.
