Fluorite Build Guide

Fluorite Xaihi Perlica Estella

F2P Friendly team that uses Fluorite as your main damage source. Xaihi helps with Fluorite’s Damage but also applies Cryo Inflictions to help trigger Fluorite’s Combo Skill. Estella is there for extra Cryo Inflictions, but you can replace her with Gilberta or Ardelia. Perlica is there just for the Combo Skill, which is easy to trigger and applies Electrification, increasing the Arts Damage of your team.

Fluorite Xaihi Alesh Estella

Another F2P Friendly team that uses Fluorite as the Main DPS. She can’t benefit from Physical Susceptibility, but has good synergy with Cryo units. Alesh can force Solidification using only Cryo Infliction by using his Battle Skill and Xaihi provides Sustain and Nature/Cryo Amplification.

Last Rite Fluorite Xaihi Ardelia

Last Rite focused team that uses Fluorite to increase the number of Cryo Infliction on enemies.

Best Weapons

• Best-in-Slot: Navigator
• Alt: Opus: The Living
• Alt: OBJ Velocitous

All of Fluorite Weapons require her to trigger Corrosion to enemies, and since they are all equally restrictive, this makes Navigator the best option for her. It provides a lot of Crit Rate and even more after applying Corrosion to enemies.

In case you don’t have Navigator with you, both Opus: The Living and OBJ Velocitous are good options for her, with Opus: The Living taking higher priority thanks to the Crit Rate it provides.

Gear

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

The MI Security Set offers a lot of Crit Rate for Fluorite, which will be using a lot of Basic Attacks through the fight, making it easier to stack and get all the extra Stats.

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

The Tide Surge Set requires applying an Arts Burst on enemies, which isn’t hard for Fluorite, as she increases the number of Inflictions on enemies.

Basic Attack > Ultimate > Battle Skill >= Combo Skill

Since Fluorite’s Combo Skill and Battle Skill will require some setup, it’s better to focus on her Basic Attacks for damage while waiting for enough Arts Inflictions on enemies. Ultimate gives great damage so level them after your Basics. Battle Skills and Combos share priority since you’re always waiting for the right moment to use them.

• P1 Ten-Finger Smith
• P2 Mind Reading Technique
• P3 Triple Surprise
• P4 Prank Master
• P5 Craver of Chaos

As a 4-Star Operator, Fluorite’s Potentials are easier to obtain and greatly increases her Damage potential. Potential 3 is one of the best ones since it synergizes with her Combat Talent for increased damage against slowed enemies. Potential 5 can help with some extra Combo Skills but it depends on your team to apply more Cryo/Nature inflictions.

Fluorite is better used to support Nature and Cryo teams by using her Combo Skill. Stacking 2 or more Cryo or Nature Inflictions triggers her Combo Skill, dealing damage to enemies and increasing the number of Inflictions stacks by one. This helps you reach either Cryo or Nature Bursts, or just get a better Arts Reaction thanks to the increased stacks. But don’t rely on her Combo Skill, as it has a long Cooldown and it won’t be a reliable source of extra stacks.

Her Battle Skill slows enemies and explodes after some time, dealing damage and applying Nature Infliction to all enemies in the area. The slow synergizes with her Combat Talent, which increases her Damage against Slowed Enemies. 

Her Ultimate is great for damage and you should use it right after using her Battle Skill, as it forces an early explosion, increasing the damage and area of effect of her Battle Skill.

Most of the time Fluorite will just wait until the enemy has enough Cryo or Nature Inflictions to use her Combo Skill, use it whenever available, as it has a long cooldown. If you’re playing around Corrosion/Solidification/Inflictions, make sure that Fluorite’s Battle Skill won’t mess up your other Operators’ Combo/Skills. If you can, use it to apply Nature Inflictions to enemies. If her Ultimate is available, use it right after her Battle Skill for extra damage and better AoE.

Fluorite will release on January 22nd, 2026 along with the release of Arknights: Endfield.

Fluorite is a Standard Operator, meaning they are permanently available through the gacha system.
