What attribute is Fluorite?

Fluorite is a 4-star Nature operator of the Caster class, from Endfield Industries, wielding a Handcannon, released in version 1.0.

What is the best weapon for Fluorite?

OBJ Velocitous is the closest fit on the data: it is a 5-star Handcannon with 411 base ATK at level 90, and its skills act on ATK. Howling Guard is the best 4-star alternative.

Taking one combat skill from level 1 to 12 costs 172,200 T-Creds and 21× Blighted Jadeleaf among other materials. The Materials tab lists every item per level.

Where these rankings come fromThe weapon order, gear sets and Potential verdicts on this tab are prydwen.gg’s, measured in play and condensed to a sentence each. Relative damage figures are ratios against the bottom of each ranking, not absolute numbers, and each one holds only for the Potential and team its row states. Everything else (base stats, skill text, material totals) is read from the game’s own data.

Fluorite can build for faster Ultimate gain or Combo Skill reduction, and Frontiers still nets good Ultimate gain from a flex piece and weapon, though a damage build is possible too, Infliction usually matters more.

3PC3-piece set effect: Wearer's Arts Intensity +30. After the wearer applies Combustion, the wearer gains Heat DMG +50% for 10s. After the wearer applies Corrosion, the wearer gains Nature DMG +50% for 10s. The aforementioned effects cannot stack.

No Set: In teams stacking Arts Infliction her Ultimate adds one extra stack, and since she has no other buffing sets to run yet, building full Ultimate Gain Efficiency is recommended.

Cryo · SolidificationStands in for Perlica

Last Rite is the Solidification carry every account can reach without a Chartered banner, and Tangtang covers the mob clear her own kit is thin on. Xaihi’s Amp is high enough that Prydwen credits much of this team’s damage to her buffs rather than to Last Rite’s own numbers.

Nature · sustained Arts BurstStands in for Perlica

Typhoeus deals her damage over a sustained Arts Burst rather than a single spike, which suits exactly two enemies on the field and less anywhere else. Prydwen debuted the team at T0.5 and is still watching how it holds up against faster single-target squads.

The Battle Skill DMG Boost is a Multiplicative Bonus.
100 Ultimate Energy

Fluorite quickly moves in an arc and rapidly fires at the target within the arc to deal 4 sequences of Nature DMG. If an Improvised Explosive has been stuck to the target, the skill detonates it immediately and increases the DMG and size of the explosion. If the final DMG sequence hits a target with at least 2 stacks of Cryo Infliction or Nature Infliction, then apply the same Arts Infliction again.

What attribute is Fluorite?: Fluorite is a 4-star Nature operator of the Caster class, from Endfield Industries, wielding a Handcannon, released in version 1.0.
What stat does Fluorite scale on?: Fluorite's skills multiply ATK. That is read from the scaling rows on the Battle Skill and Ultimate, not from the skill description, so it reflects what the game actually multiplies rather than what the text mentions.
What is the best weapon for Fluorite?: OBJ Velocitous is the closest fit on the data: it is a 5-star Handcannon with 411 base ATK at level 90, and its skills act on ATK. Howling Guard is the best 4-star alternative.
Which gear set should Fluorite use?: Frontiers. Its 3-piece effect is: 3-piece set effect: Wearer's Arts Intensity +30. After the wearer applies Combustion, the wearer gains Heat DMG +50% for 10s. After the wearer applies Corrosion, the wearer gains Nature DMG +50% for 10s. The aforementioned effects cannot stack. The 3-piece effect is the only set bonus a gear set has, and it needs three matching pieces; an operator equips four in all (Armor, Gloves and two Kits), so the fourth is free for an off-set piece.
How much does it cost to max Fluorite's skills?: Taking one combat skill from level 1 to 12 costs 172,200 T-Creds and 21× Blighted Jadeleaf among other materials. The Materials tab lists every item per level.
