The First Descendant: Hailey Sniper Build Guide to Dominate Bosses ~ HaploGamingChef

Introduction: Mastering Hailey's Sniper Build for Boss Killing in The First Descendant

Welcome, fellow The First Descendant players! Whether you’re new to the game or a seasoned pro, if you’re looking to take down the toughest bosses, you’ve come to the right place. Today, I’m going to walk you through a top-tier Hailey sniper build that’s specifically designed for boss fights. Since season 1, I’ve been using this build, and after many requests, it’s time for an update. Let’s dive into the details of what makes this sniper build so deadly!

Reactor Selection: Why the Chill Singular Reactor is Key

When building a Hailey sniper, the first thing you need to focus on is the reactor. For this build, the Chill Singular Reactor is your go-to choice. Why? Because it perfectly synergizes with Hailey’s Zenith skill, which is a chill-based attack. This reactor is key to unlocking the full potential of her damage output. Even if you don’t use super cool Kybo rounds, having the Chill Singular reactor equipped ensures you’re maximizing your damage during each shot.

Reactor Stats and Rolls: Maximizing Performance

For the optimal rolls on your Chill Singular Reactor, aim for:

Gold Rolls for Skill Critical Hit Damage and Additional Skill Attack Against Colossus. These rolls will elevate your overall damage significantly, especially in boss fights.
Sniper Rifle Mounting: This is non-negotiable. It’s essential for maximizing your effectiveness as a sniper.
Piercing Light: If you’ve been following my previous builds, you’ll already be familiar with this module. It remains one of the best choices for this setup.

External Components: Full Slayer Set for Maximum Efficiency

When it comes to external components, you’ll want to stick with the Full Slayer Set. This includes:

Auxiliary Power
Sensor
Memory
Processor

For core roles, focus on Max HP and Defense across the board to ensure survivability during long fights. For the option roles, here’s the breakdown:

Auxiliary Power: Max HP
Sensor: Max MP
Memory: Defense and MP recovery modifier
Processor: Max Shield (the second role can be whatever you prefer, but I’d stick with something that supports survivability).

Weapon Choice: Piercing Light for Boss Killing Precision

The Piercing Light sniper rifle is the cornerstone of this build. While some players prefer the Atoms, I’ve found Piercing Light to be far superior, especially for those who have already invested in it from past builds. It’s tried, tested, and remains highly effective.

For the weapon core rolls:

First Slot: Choose Firearm Attack over Chill Attack. While chill is important, Firearm Attack provides more flexibility, especially when facing enemies that aren’t weak to chill.
Second Slot: Go with Chill Attack to further boost your chill damage output.
Cerulean Core: Opt for Fire Rate. You don’t need this to be a priority, but it’s a nice-to-have since it increases your ability to land shots faster.
Yellow Cores: Skip Sprint Speed—you’re not going to be moving much with this build, so there’s no need to waste resources on it.

Weapon Option Roles: The Essentials for Maximum Damage

For weapon option roles, make sure to include:

Bonus Firearm Attack Against Colossus: This is crucial because it ties into your arcade tuning and will give you the damage boost you need.
Firearm Attack, Critical Hit Damage, and Weak Point Damage: These three roles are essential for boosting your damage across the board, ensuring your shots hit hard, especially on weak points.

Weapon Modules: Setting Up for Success

When it comes to modules, here’s what you need for your weapon:

Rifling, Reinforcement, Action, and Reaction Bullet Integration: These are all about enhancing your weapon’s overall performance.
Better Insight and Better Concentration: These will improve your accuracy and consistency with each shot.
Focus Fire: This increases weak point damage and is essential for maximizing your sniper’s effectiveness.
Weak Point Sight, Expanded Weapon Charge, and Concentrated Support Ammo: These two modules help give your Zenith skill more shots, and will make sure you don’t run out of ammo during intense fights.
Weak Point Expansion: This module works wonders for improving your weak point damage output.

Hailey’s Modules: Maximizing Critical Hit Potential

For Hailey’s modules, the goal is to maximize your critical hit rate, which is essential for this build. Here’s what I recommend:

Midair Maneuvering: This is a must-have for boosting your mod capacity and keeping you agile during fights.
Increased HP: You don’t want to be a glass cannon. This will ensure you can take a hit while still dishing out massive damage.
Skill Insight and Skill Concentration: These mods are crucial for maximizing your crit rate, especially since many bosses have high critical resistance.
Emergency Measures and Front Lines: These ensure you’re not entirely dependent on your damage output and can survive longer fights.

Boosting Chill and Firearm Attack Damage

Another key set of modules you should equip are:

Chill Specialist and Singular Specialist: These will slightly enhance your skills and provide additional benefits, helping with the overall synergy of your build.
Shot Focus: This mod increases your Firearm Attack by 15%, acting as a huge multiplier to your damage. It pairs perfectly with Cryorounds, which gives you 200% additional damage to debuffed enemies.
Dangerous Ambush: This is crucial. When your first shot knocks the enemy down, your second shot will guarantee a kill if the enemy isn’t dead already.

Arcade Tuning: The Heart of Your Sniper Build

Arcade tuning is the backbone of this sniper build. While I haven’t fully completed my arcade tuning for Hailey, I’ll walk you through the process so you can finish it yourself. Start by focusing on the firearm side of the tuning, rather than skill power. This side gives you more value overall. Grab all the Firearm Attack boosts, especially the ones against Colossus. You’ll also want to pick up the enhanced Critical Hit Rate and Firearm Attack bonuses to maximize your effectiveness in boss fights.

Inversion Reinforcer: A Key to Sustaining Damage

For the Inversion Reinforcer, you don’t need anything special for this build. If you want to debuff the enemy, you can use Focus Rounds, but I find it unnecessary since you can take down most bosses in a couple of shots anyway. Stick with a regular farming build for this and you’ll be fine. Focus more on arcade tuning to get the biggest boost in damage output.

How Hailey’s Sniper Build Performs in Combat

Now that you have the full rundown of this sniper build, let’s talk about how it performs in actual boss fights. I’ve tested it on some of the toughest bosses in the game, and it’s a beast.

Frost Walker: With the right positioning and the correct use of your Zenith skill, you can easily take down the Frost Walker with just two shots. Sometimes, you can even get a one-shot kill, depending on how well you line up your shot.
Molten Fortress: With this build, killing Molten Fortress is a breeze. The combination of Piercing Light and Firearm Attack makes short work of this boss.
Gluttony: The build also excels against Gluttony. Aim for the kneecap and follow up with a second shot to finish the job. If you’ve set up your mods and tuning correctly, even tough bosses like this don’t stand a chance.

Advanced Tips: Making the Most of Hailey’s Sniper Build

Once you’ve got the core build and mechanics down, you’ll want to master a few advanced strategies to push your damage output even further. These tactics will help you become a true boss-killer with Hailey.

Positioning is Key: Hailey’s sniper rifle rewards precision, so always prioritize high ground or areas with clear lines of sight. When possible, try to stay behind cover to mitigate damage while setting up your shots.
Utilizing Weak Points: Always aim for weak points, whether they’re the head, weak spots on the limbs, or any other vulnerable area on bosses. Snipers excel in this area, so maximizing your weak point damage will make a huge difference.
Zenith Skill Timing: Don’t waste your Zenith skill. Use it during the boss’s vulnerability phase. These moments are the perfect time to unleash maximum damage. Proper skill timing can make the difference between a prolonged battle and a swift victory.
Ammo Management: Since the Piercing Light sniper isn’t a rapid-fire weapon, you’ll need to be conscious of your ammo. Make sure you have sufficient ammo recovery mods to replenish your shots during longer fights, or rely on team support if you’re in multiplayer.

Synergy with Team Play: Complementing Your Allies

While Hailey’s sniper build is designed to dominate bosses solo, you’ll still get the most out of her if you’re playing with a team. Here’s how to sync up with your squad for the best results:

Focus Fire with Damage Dealers: Pair with high DPS characters to take down bosses faster. Your job is to maximize your weak point damage while the other players apply constant pressure with their abilities.
Support Characters: If you have a support player on your team, coordinate with them to ensure you never run low on shields or health. Hailey’s sniper build works best when you don’t have to worry about healing yourself.
Crowd Control: If your team has a crowd control specialist (like a tank or CC-based character), use that opportunity to land devastating sniper shots while the boss is immobilized or distracted.

How to Customize Your Sniper Build for Different Bosses

While this sniper build is generally effective across various bosses, certain adjustments can help optimize your performance against specific targets. Here’s how to tweak your build for different encounters:

Against Fast or Mobile Bosses: If the boss is constantly moving, you may want to include some aim-assist modules or focus on increasing your sniper fire rate. This ensures you land more consistent hits, even if the enemy is hard to track.
Against Tanky Bosses: For bosses with high health pools or massive shields, prioritize armor-piercing mods and bonus damage against Colossus. This will allow you to break down their defenses more effectively.
Against Multiple Bosses: In fights where you’re up against several bosses at once, you’ll need to focus on ammo regeneration and damage over time effects. Equip mods that increase your area of effect (AoE) damage or debuffs, and make sure you’re using precision shots to minimize wasted ammo.

Combat Scenarios: Hailey Sniper Build in Action

Let’s take a look at a few combat scenarios to see how this build truly performs in various situations:

Solo Boss Fights: Whether you're fighting against Frost Walker or Molten Fortress, you’ll notice that your damage output is insane with this build. The combination of a high critical hit chance, piercing damage, and Zenith skill usage allows you to take these bosses down with minimal effort. The key is positioning and patience. Take your time, find the weak spots, and wait for the right moment to fire.
Team Fights: In team-based scenarios, your role as a sniper is to provide precision damage while your teammates handle the more dynamic aspects of the fight. With Chill Singular Reactor and your Piercing Light sniper, you’ll be able to take down even the toughest bosses like Gluttony or Titan in no time.

The Best Playstyle for Hailey Sniper Build

To truly get the most out of Hailey’s sniper build, you need to adopt a careful and strategic playstyle. Here’s a breakdown of what works best:

Patience: You’re not going to be rushing into combat like some of the more aggressive characters. Hailey thrives on precision, so take your time and line up those shots.
Mobility: Even though you’re not a front-line fighter, you’ll need to remain mobile. Use Hailey’s Midair Maneuvering module to dodge incoming attacks and reposition yourself. Always stay a step ahead of the enemies.
Positioning: Always prioritize high ground or a spot with an uninterrupted line of sight. This is key to maximizing the effectiveness of your sniper rifle.

Weaknesses and Limitations of the Hailey Sniper Build

No build is perfect, and it’s important to understand the potential weaknesses of Hailey’s sniper setup:

Vulnerability During Reloads: Reloading can leave you exposed, especially during boss fights. Always ensure you have enough cover, or consider using ammo regeneration mods to reduce downtime.
Vulnerability to Close Combat: While the sniper rifle excels at long-range combat, Hailey isn’t as effective in close-quarters combat. You’ll need to rely on your teammates to protect you from being overwhelmed by melee enemies.
Skill Dependency: The build heavily relies on Zenith skill for maximum damage output. If your skill gets interrupted or if you miss, your damage will drop significantly. Make sure to time it right!

Conclusion: Hailey Sniper Build – Dominating Bosses Like a Pro

Hailey’s sniper build is one of the most powerful setups you can use in The First Descendant. By focusing on high critical hit damage, piercing shots, and the synergy between her Zenith skill and the Chill Singular Reactor, you’ll be able to dismantle even the toughest bosses with ease. Whether you're playing solo or with a team, this sniper build offers the precision and firepower you need to win any battle.
