Fluorite Build Guide

Last Rite Xaihi Fluorite Ardelia

Last Rite team that uses Xaihi and Fluorite to apply extra Cryo Inflictions. Avoid using Fluorite Battle Skill as Last Rite wants as many Cryo Inflictions as possible. Ardelia can be replaced with other buffers like Perlica or Gilberta as well.

Yvonne Last Rite Xaihi Fluorite

Yvonne team that focuses on increasing Yvonne’s damage as much as possible. Note: Last Rite helps enable Yvonne, but Yvonne does not enable Last Rite. Xaihi is the main buffer for the team, so focusing her build on Intellect and Ultimate Gain is key.

Note: You can use Fluorite as your Main DPS, but it won't perform as well as the teams above.

Best Weapons

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

OBJ Velocitous will not be the best personal damage for Fluorite, but it provides Ultimate Gain Efficiency, which is important for Fluorites support capabilities.

Navigator and Opus: The Living are both good options if you want to increase Fluorite's personal damage, and the extra Energy Gain is not noticeable in your rotations.

Gear

• Gear Set: Frontiers
• Armor: Frontiers Armor T3
• Gloves: Eternal Xiranite Gloves T1 Eternal Xiranite Gloves
• Kit 1: Frontiers Extra O2 Tube
• Kit 2: Frontiers Extra O2 Tube

Either Glove is fine since they both give Intellect and Ultimate Gain.

Fluorite's Combo Skill Cooldown is extremely long (40s). It reduces by 2 at max level (which is very high investment). The main ways of reducing this are through Frontiers and Fluorite's P5 Craver of Chaos, which is quite accessible as Fluorite is a 4-Star.

Alternative Gear

• Gear Set: None
• Armor: Tide Fall Light Armor
• Gloves: LYNX Gloves
• Kit 1: Redeemer Seal
• Kit 2: Redeemer Seal

While Frontiers reduces your Combo Skill Cooldown, the individual pieces aren't that great and the Set Effect can't be triggered by Fluorite. Depending on your team and rotation, maximizing Fluorite's Ultimate Gain Efficiency can feel much better.

Other sets will increase Fluorite's personal damage, but in a meta context, Fluorite should be built as a supportive Operator for Cryo teams.

Combo Skill = Ultimate >>> Basic Attack = Battle Skill

Right now, Fluorite is mainly used for her extra Cryo Infliction on Combo Skill and Ultimate. Her Basic Attack won't provide much damage, and Battle Skill is not used since it will trigger an Arts Reaction with Nature Infliction. We don't want to do this as Yvonne and Last Rite both want as many Cryo Inflictions to consume as possible.

• 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 is the main goal, as it buffs Fluorite's main team contribution, her extra Infliction on Combo.

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. Her Ultimate will do the same thing, just on a different resource system.

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. 

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. Having a Nature Infliction on an enemy will mean the next Cryo Infliction will consume both and trigger Solidification.

In Yvonne / Last Rite teams, just ignore Fluorite's Battle Skill completely, unless you are running someone like Perlica who can trigger Electrification with the Nature Infliction.

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.
