Fluorite Guide & Best Builds

Welcome to our Fluorite build guide for Arknights: Endfield. Fluorite is a 4-Star Handcannon Caster Character available in Arknights: Endfield who utilizes the Nature element.

In our Fluorite guide, we'll cover everything you need to know to get the most out of your Fluorite, from building the best Gear and Weapons, to important stat priorities and combos.

Fluorite's Best Weapons

OBJ Velocitous
  • Agility Boost [M] +124.0 (9/9)
  • Ultimate Gain Efficiency Boost [M] +37.14% (9/9)

Detonate: Rapid Strike:
ATK +14%. After the wielder consumes an Arts Infliction, the wielder gains Nature DMG Dealt +[14%×Stacks Consumed] for 20s. Effects of the same name cannot stack.
OBJ Velocitous is not only her intended Signature Weapon, but also the one most people would call her best fit despite it being a 5-star option. This weapon boosts her personal damage while she's applying status effects and corrosion. There isn't really a definitive option for Fluorite, as all her weapons have strengths and weaknesses, but depending on the situation, this weapon is a solid all-rounder choice for her.
Home Longing
  • Agility Boost [L] +156.0 (9/9)
  • Cryo DMG Boost [L] +43.33% (9/9)

Suppression: Olden Moon:
ATK +11.2%. For 20s after the wielder casts a combo skill, the wielder's next battle skill gains Cryo and Nature DMG Dealt +12.8%. Max stacks for effects of the same name: 2. Duration of each stack is counted separately.
Home Longing is arguably Fluorite's Best in slot weapon to maximize her own damage. It grants a Battle Skill damage increase after the wielder casts a Combo skill, which is useful in chaining her attacks, specifically when slotted into a team with Last Rite and Tangtang. While the weapon does have a secondary stat boost she cannot take advantage of, the interplay between her kit and the weapon further empower Fluorite's Improvised Explosive through the use of her Combo Skill.
Wedge
  • Main Attribute Boost [L] +132.0 (9/9)
  • Critical Rate Boost [L] +19.5% (9/9)

Infliction: Wedge of Civilization:
Arts DMG Dealt +19.2%. When the wielder casts a battle skill, the wielder gains Arts DMG Dealt +12.8% for 15s. When the wielder's battle skill applies an Arts Reaction, the wielder gains Arts DMG Dealt +25.6% for 15s. The two effects apply separately and do not stack with themselves.
Wedge Wedge is a fantastic weapon to use with Fluorite. It grants a solid Arts DMG Dealt buff and also gains a decent Arts DMG Dealt buff for 15s When the wielder casts a battle skill. Further, when the wielder's battle skill applies an Arts Reaction, the wielder gains an additional sizable Arts DMG Dealt boost for 15s. Given the nature of Fluorites kit this weapon works very well with her abilities, this weapon is a perfect accompaniment.
Navigator
  • Intellect Boost [L] +156.0 (9/9)
  • Cryo DMG Boost [L] +43.33% (9/9)

Infliction: Lone and Distant Sail:
Critical Rate +5.6%. When Solidification or Corrosion is applied to enemies, the wielder gains Cryo DMG Dealt and Nature DMG Dealt +5.6%, and Critical Rate +3.2% for 15s. If this effect is triggered by the wielder, double the increase gained. Effects of the same name cannot stack.
Navigator is more situationally useful specifically when running teams with characters such as Ardelia and Yvonne. Navigator grants a flat Critical Rate boost and when Solidification or Corrosion is applied to enemies, the wielder gains a small buff to Nature DMG Dealt and Critical Rate for 15s. So long as there’s a Cryo Infliction operator on the team Such as Snowshine or Estella Triggering a Corrosion should be no issue for Fluorite making this ability have a lot of uptime.
Howling Guard
  • Intellect Boost [S] +93.0 (9/9)
  • ATK Boost [S] +23.4% (9/9)

Suppression: Emergency Boost:
When the wielder's battle skill hits the enemy, the wielder gains ATK +33.6% for 20s. Effects of the same name cannot stack.
For a 4 Star Option, Howling Guard will work well. The fact is though that with the availability of 5 Star options, this weapon should only ever really be used in a leveling situation and replaced with something better as soon as possible.

Fluorite's Best Essences

Essences are one of the repeatedly farmable ways to further boost the weapon effects of your Fluorite. Which area and essence you will want to farm will depend on the weapon you are playing, as not all Essences are compatible with every weapon. Essences will increase the stats of your weapon, as well as enhance the passive effect it provides.

  • OBJ Velocitous: Agility, Ultimate Gain Boost, and Detonate, farmable in The Hub, Wuling City, and Qingbo Stockade.
  • Home Longing: Agility, Cryo Damage, and Suppression, farmable in The Hub, Originium Science Park, Origin Lodespring, Qingbo Stockade, Test Area, and Yinglung Pass.
  • Wedge: Main Attribute, Critical Rate Boost, and Infliction, farmable in Originium Science Park, Origin Lodespring, Power Plateau, Marker Stone, Yinglung Pass, and North Wuling Exclusion Zone.
  • Navigator: Intellect, Cryo DMG Boost, and Infliction, farmable in Originium Science Park, Origin Lodespring, Test Area, and Yinglung Pass.
  • Howling Guard: Intellect, Attack Boost, and Suppression, farmable in The Hub, Originium Science Park, and Yinglung Pass.

Essences can be further upgraded through a system called Etching which will be a long-term investment due to how much Sanity it takes to fully max out a weapon. You may therefore want to farm and Etch Essences for a signature weapon already if you plan on getting it in the near-future, even if you do not have the weapon yet. A simple +1/+1/+1 Essence for a temporary weapon like Howling Guard will be good enough until you can get your hands on Fluorite's OBJ Velocitous, or attain Navigator from the pass weapon selector, or Wedge from Arsenal Ticket draws.

Best Gear for Fluorite

Qingbo
3-piece set effect: Wearer's Combo Skill Cooldown Reduction +15%. When the wearer casts a combo skill, the wearer gains Skill DMG Dealt +20% (for every skill) for 15s. This effect can reach 2 stacks. Duration of each stack is counted separately.
This set reduces Fluorite's Combo Skill Cooldown, and boosts her Skill DMG with every Combo Skill usage, which naturally fits her playstyle. Additionally, Ultimate Gain Efficiency is stacked. This combination of benefits helps Fluorite become a support Infliction applier.
Type 50 Yinglung
3-piece set effect: Wearer's ATK +15%. When any operator in the team casts a battle skill, the wearer gains 1 stack of Yinglung's Edge that gives DMG +20% to the wearer's next combo skill. Yinglung's Edge can stack 3 time(s).
This set is particularly synergistic with the Home Longing Handcannon. While her best set remains mostly the same, this is a new alternative that presents a different playstyle opportunity for Fluorite in the Meta. That being said, it is recommended to play this set specifically in a team alongside Last Rite and Tangtang for the best results.

Leveling Gear for Fluorite

The below set is craftable quite early into your journey on Talos-II-

Mordvolt Insulation
The 3-Piece set effect for this gear grants the Wearer a sizable Intellect boost. In addition, when the wearer’s HP is above a certain percentage, Arts DMG is given a solid buff. This set is an alternative option of lower rarity for Fluorite that focuses on boosting attack and SP Gains. The Mordvolt Security set doesn’t have Glove's that match the Intellect + Agility combination, which necessitates an offset option. Fluorite benefits from the MI Security Hands PPE which boasts a sizable Basic Attack Damage Bonus and slot nicely to round out the gear selection. Please Note: Intellect + Agility as well as Agility + Intellect gear options are limited at launch, so this information may be updated in a future update. Please check back in the future for the most up to date information.

Fluorite's Skill Priority

Skill Priority: Signature Gun Kata > Apex Prankster > Tiny Surprise = Free Giveaway

Start with her Basic Attack, as a majority of her outgoing damage is done through it. Following that we focus on the Ultimate due to the buffs to the sequence damage stages it offers, allowing her to output a lot more damage during her Ult. Her combo skill and normal skill both offer the lowest damage multiplier scaling, so which one you choose over the other makes little difference. That being said, her normal skill gains a slight increase to her Slowing effect, which is why you may want to prioritize it higher than her combo.

How to Play Fluorite

Fluorite shines in instances where she can act as a support to stronger DPS options like Last Rite, and Yvonne. In particular, her abilities are geared to support Cryo and Nature operators. Her combo skill in particular has the ability to apply additional arts inflictions match ng an already applied arts infliction on an enemy but she also has Slow in her kit which has a lot of use cases as well.
