Fluorite

endgame 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.

This is Fluorite's endgame support setup and it is deliberately built around one thing: firing her Ultimate as often as possible. OBJ Velocitous supplies the Ultimate Gain she needs, and the Qingbo set adds a 15% Combo Skill cooldown reduction plus a stacking Skill DMG buff whenever she casts that Combo Skill, so her Free Giveaway and Apex Prankster keep trading places in the rotation. Qingbo Heavy Armor, Qingbo Gloves and Qingbo Bamboo Cutter supply three of the four slots, and a Redeemer Seal closes the set while pushing Ultimate Gain higher still. The point is not her damage output; it is that she keeps feeding extra Cryo or Nature Infliction stacks into a team that can convert them into Arts Reactions.

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 is picked purely for its Ultimate Gain because it is the only support weapon whose effect she can actually trigger.

Clannibal and Brigand's Calling are skipped since her kit cannot meet their activation conditions.

Qingbo lowers her Combo Skill cooldown and gives her a stacking Skill DMG buff when she casts it, which speeds up her Infliction loop.

Redeemer Seal fills the leftover slot so the set bonus stays complete while adding more Ultimate Gain.

Treat other weapons as personal damage options only; they do not improve what she brings to the team.

Notes

Ultimate Gain is the stat that matters most here; drop damage rolls for it whenever you have to choose.
The Qingbo bonus trims Combo Skill cooldown so her rotations stop stalling between Free Giveaway casts.
The Detonate essence roll is a small bonus, not a reason to pick the weapon on its own.
