Fluorite

early game support

sub_dpssupportinflictionnaturecryo

Fluorite is a 4-star Nature Caster whose job is stacking extra Cryo or Nature Infliction on enemies so her team can cash in Arts Reactions. Her own numbers are low, so she only really pays off in comps built around Infliction consumption, and her Battle Skill is currently unused in her recommended rotations. That narrowness is why she lands in the bottom tier overall.

Fluorite's early game build is a budget way to keep her Ultimate running while you assemble better gear. OBJ Velocitous remains the weapon of choice since it is the only option whose effect her kit can trigger, and the Catastrophe set provides Ultimate Gain Efficiency from its bonus along with an instant 50 SP restore at the start of combat. Catastrophe Heavy Armor T1, Catastrophe Gloves and Catastrophe Filter fill the first three slots, with Mordvolt Insulation Battery T1 plugged in as the off-piece because of its high Ultimate Gain. The result is a low-investment enabler that still alternates Combo Skill and Ultimate to supply her team with extra Infliction stacks.

Insights

Core Mechanics

Her Tiny Surprise Battle Skill sticks an Improvised Explosive onto a target, Slows it, then detonates for Nature damage and a Nature Infliction stack in the blast area; only one bomb can exist at a time.
Killing the bombed target triggers the explosion early, so it is usually worth planting the bomb on the squishiest enemy in range rather than the tankiest one.
Her Free Giveaway Combo Skill fires whenever an enemy already carries two or more Cryo or Nature Infliction stacks, dealing Nature damage and duplicating whatever Arts Infliction is already on the target.
Infliction duplication is her real contribution: she copies the element already applied instead of forcing a new one, which keeps reaction setups intact for her allies.
The Apex Prankster Ultimate fires four Nature damage sequences; if a bomb is attached it detonates immediately with increased size and damage, and if the final hit lands on a target with two Cryo or Nature stacks it re-applies the same Infliction.

Scaling

Early on she functions as a cheap extra Infliction source, but her personal damage stays flat because her multipliers are modest even at high skill levels.
Her ceiling is tied to teammates: the more allies she has that apply or consume Cryo and Nature Infliction, the more often Free Giveaway comes online.
Ultimate uptime matters more than raw stats, which is why Ultimate Gain is stacked over damage stats in every recommended build.
In squads with no other Infliction stackers she underperforms noticeably and is not worth a slot.

Team Role

Fluorite is a bench-style support who should be fielded as a teammate rather than the Controlled Operator. She does not carry fights herself; she widens the Infliction window for whoever does. Slot her next to operators that apply Cryo or Nature Infliction so that Free Giveaway can trigger on the two-stack threshold, and so the duplicated Infliction she copies actually gets consumed by an Arts Reaction. Teams that already run two or more Infliction appliers get the most value, because her Combo Skill turns their setup into a repeatable loop rather than a one-off burst window. Because her Battle Skill is not part of her current rotations, think of her as a passive enabler who occasionally fires her Ultimate for a second wave of stacks. She is a poor fit for Physical, Heat, or Electric compositions, and she should be benched whenever the squad has no other stackers to feed off.

Explanation

OBJ Velocitous stays in place because it is still the only weapon whose effect she can realistically activate, regardless of progression stage.

The Catastrophe set is the cheap route to Ultimate Gain, since both its set bonus and its individual pieces push that stat.

Mordvolt Insulation Battery T1 covers the fourth slot as an off-piece with strong Ultimate Gain instead of chasing a full second set.

The goal is simply to reach her Ultimate every other rotation so the team keeps receiving extra Infliction stacks.

There is no fallback weapon worth listing; alternatives would only raise her own damage and not her support value.

Notes

Catastrophe's set effect grants Ultimate Gain Efficiency plus an immediate 50 SP refund when the fight starts.
Mordvolt Insulation Battery T1 is used as the off-piece purely for its high Ultimate Gain contribution.
Swap into the Qingbo setup once you can farm it; this version exists to keep her Ult cycling while gearing up.
