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

Suppression: Olden Moon (4/9):
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.

is arguably 's Best in slot weapon to use as of Version 1.1, due to the teams she is currently being utilized in. 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 and . 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.

Infliction: Wedge of Civilization (4/9):
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 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.

Infliction: Lone and Distant Sail (4/9):
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 and . 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 or Triggering a Corrosion should be no issue for Fluorite making this ability have a lot of uptime.

Detonate: Rapid Strike (9/9):
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.

For a 5 Star option, 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 pumps up her personal damage while shes applying status effects and corrosion. There isnt really a definitive option for as all her weapons have strengths and weaknesses, but depending on The situation this may be a better option for her until more varied options are available.

Suppression: Emergency Boost (9/9):
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, 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 damage 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.

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

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

3-piece set effect: Wearer's Critical Rate +5%.
After the wearer scores a critical hit, the wearer gains ATK +5% for 5s. This effect can reach 5 stacks. At max stacks, grant an additional Critical Rate +5%. This effect cannot stack.

The MI Security 3-piece set effect gives a flat boost to the wearer's Critical Rate and also grants the wearer a slight attack boost for a few seconds after the wearer scores a critical hit. This effect can stack and reach 5 stacks. At max stacks, it also grant an additional slight Critical Rate boost. Shell also receive a substantial basic attack boost from the MI Security Overalls Chest gear, and MI Security Hands PPE Gloves, and a critical rate boost from the MI Security Toolkit.

Body: MI Security Set — Intellect, Agility, Basic Attack DMG Bonus
Gloves: MI Security Set — Intellect, Agility, Basic Attack DMG Bonus
Kit 1: MI Security Set — Intellect, Agility, Critical Rate
Kit 2: MI Security Set — Intellect, Agility, Critical Rate

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 new 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 and for the best results.

Body: Type 50 Yinglung Set — Agility, Intellect, Combo Skill DMG
Gloves: Redeemer Armor Offpiece — Agility, Ultimate DMG Bonus
Kit 1: Type 50 Yinglung Set — Agility, Intellect, Combo Skill DMG
Kit 2: Type 50 Yinglung Set — Agility, Intellect, Combo SKill DMG

Leveling Gear for Fluorite

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

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.

Body: Mordvolt Insulation Set — Intellect, Agility, Normal Attack Efficiency
Gloves: MI Security Offset — Intellect, Agility, Basic Attack DMG Bonus
Kit 1: Mordvolt Insulation Set — Intellect, Agility, Ultimate SP Gain
Kit 2: Mordvolt Insulation Set — Intellect, Agility, Attack DMG Bonus

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: > > =

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.
