Arknights Endfield Fluorite Build: Skills, Weapons, Teams Guide

Looking to maximize your Nature team's damage? Fluorite is your answer. This guide covers the best builds to turn her Corrosion into pure, unadulterated destruction.

Fluorite Overview

Fluorite is a standout 4-Star Caster in Arknights: Endfield and a total gem for Nature teams. As a reliable Sub-DPS, she really shines when paired with Nature or Cryo allies. Her Corrosion ability is the real star—it chips away at enemy resistance over time, making her super useful in all sorts of fights. Whether you’re F2P or just looking to round out your squad, Fluorite is an easy pickup with Potentials that boost her damage nicely. Don’t sleep on this one!

Fluorite Skill Priority in Arknights Endfield 

Basic Attack > Ultimate > Battle Skill >= Combo Skill

Fluorite’s Combo Skill and Battle Skill both need a bit of setup to shine, so focus on spamming her Basic Attacks for damage while you wait to stack enough Arts effects on enemies. Her Ultimate hits like a truck, so level that up after you max out your Basics. Battle Skills and Combos are equally important here—you’ll just want to hold onto them for the perfect moment.

Best Weapons for Fluorite

The choice of weapon is crucial for maximizing Fluorite's damage potential, and all her optimal weapons rely on triggering Corrosion on enemies to unlock their full power.

Best Choice

Navigator

This weapon is the top choice for Fluorite. It provides a substantial amount of Crit Rate, and when Corrosion is applied to enemies, the Crit Rate boost becomes even more significant. This synergy perfectly aligns with Fluorite's combat style, where she relies on consistent damage output through basic attacks and skills.

F2P

OBJ Velocitous

For F2P players, OBJ Velocitous is a reliable alternative. While it may not offer the same level of Crit Rate as Navigator, it still provides decent stats that allow Fluorite to perform well in combat. It's a great option to use until you can obtain a more powerful weapon.

Alternative

Opus: The Living

Opus: The Living is another solid choice. It also grants Crit Rate, and in situations where you don't have Navigator, it takes priority over OBJ Velocitous. The Crit Rate it provides helps maintain a good damage output, making it a viable middle - ground option.

Best Gear Sets for Fluorite 

Two gear sets stand out for Fluorite, each catering to different combat strategies.​

①Gear Set:

MI Security Set​

• Armor: MI Security Overalls​
• Gloves: MI Security Hands PPE​
• Kit 1: MI Security Toolkit​
• Kit 2: MI Security Toolkit​

Set Effect: The MI Security Set is ideal for Fluorite due to its focus on Crit Rate. Since Fluorite uses basic attacks frequently during battles, the Crit Rate boost from this set makes it easier to stack up additional stats and land critical hits consistently. This significantly enhances her overall damage output, especially in prolonged fights where basic attacks play a major role.​

②Gear Set:

Tide Surge Set​

• Armor: Tide Fall Light Armor​
• Gloves: Frontiers Blight RES Gloves​
• Kit 1: Turbid Cutting Torch​
• Kit 2: Turbid Cutting Torch​

Set Effect: The Tide Surge Set is a viable alternative when Fluorite is part of a team that can regularly trigger Arts Bursts on enemies. Fluorite's ability to increase the number of Inflictions on enemies makes it relatively easy to meet the set's requirement of applying an Arts Burst. When activated, this set boosts her damage, making it a good choice if your team composition is built around Arts - based damage and frequent element interactions.

Best Teams for Fluorite in Arknights Endfield

This is a totally F2P-friendly team with Fluorite as your go-to main damage dealer. Xaihi not only cranks up Fluorite’s damage output but also slaps on Cryo effects to help activate her Combo Skill. Estella is there to pile on more Cryo, but feel free to swap her out for Gilberta or Ardelia if you want. Perlica’s sole job is to trigger the Combo Skill — it’s super easy to pull off and also inflicts Electrification, which gives your whole team a nice Arts damage boost.

Here’s another F2P-friendly squad where Fluorite takes the main DPS role. She doesn’t get any love from Physical Susceptibility, but she pairs perfectly with Cryo allies. Alesh can force Solidification using nothing but Cryo from his Battle Skill, and Xaihi keeps your team alive while amping up Nature and Cryo damage.

This team is all about Last Rite, with Fluorite leading the charge to spam as much Cryo on enemies as possible.

Conclusion

That concludes our Fluorite build guide. Follow these recommendations for team composition, skill priority, and playstyle, and you’ll turn this accessible 4-star into a reliable damage dealer for your F2P roster. Best of luck building your squad and dominating the battlefield!
