/Intellect/Support Lingering Glow DPS Rewrite
Introduction
Lorentz Butterfly is a 6-star Intellect character in Reverse: 1999. Lorentz Butterfly's role is Support Lingering Glow DPS Rewrite. Damage type: Mental.
On the combined Reverse: 1999 tier list Lorentz Butterfly is S tier, 17th of the 129 characters ranked, from where 2 community tier lists put Lorentz Butterfly.
Other Intellect characters in Reverse: 1999: 6, Aleph, Beryl, Corvus, Door, Enigma and 6 more.
What Lorentz Butterfly does
A Lingering Glow support who also hits hard: The Primer's Flutter deals 800% Mental, applies 3 Burn first, and then echoes a share of all the damage allied incantations did to that target this round. Her Ultimate copies one basic incantation into 3 precast duplicates for the next round, and her basic incantations rank up when you queue matching ones together.

Stories
9Additive Manufacturing Device
A Demonic Scale-based additive manufacturing machine, powered by tens of thousands of arcane skills operating simultaneously.
Every arcane skill within the printer is interconnected. Even the slightest deviation in initial conditions can lead to drastically different results.
According to the interviewee, the device can provide whatever help is needed—whether it's a sniper rifle or a toaster.
"Antenna"
A weighty metal ornament, set with gemstones, its tip trembling faintly like an insect's antenna. The interviewer learned that the interviewee helped design this hairpiece herself.
"Sensing its surroundings, relaying information, even tracking a target? No—it's simply a decorative piece inspired by a tuning peg."
Liquid Metal-Coated "Glove"
A pair of gloves with a metallic sheen, shimmering like the scales on a butterfly's wings.
Though the interviewee described them as the arms of an Awakened, we know they are simply the latest product of the LSCC—refined, of course, by Institutum Lorentz.
Deadly Cello
A cello and bow of distinctive design. Like any musician who cherishes their instrument, the interviewee holds them dear.
The interviewer accepted the interviewee's offer of an impromptu performance—the deep, resonant tone was enchanting. "Just a bit of technique," the interviewee said with a smile, setting the bow aside. "It's a beautiful instrument. Would you like to try it?"
"ID"
She can be Ms. Jones, Special Investigator of the St. Pavlov Foundation, or Marguerite, researcher of the Laplace Scientific Computing Center. Any identity will do, as long as it opens the right doors.
"A String of Notes"
A string of notes, a fragment of melody. Made from the same metal as her hairpiece, it's the perfect finishing touch on the interviewee's gown.
Smooth, cold, and as light as the flutter of a butterfly's wings. When her target's life fades along with the final note, that is all they will ever feel.
The Beginning of Chaos
Eras bounce like marbles—backward, forward, backward again. Mostly backward, right?
She learned what 1999's Cambridge had to teach her. Her gift allows her to pick up on patterns intuitively, but her nature ensures she will always be a skeptic. And here lies the paradox that the rise and fall of eras brings—one that traps everyone who still remembers, who still thinks: Are we moving forward or backward? What can we hold on to?
Yes, the storms of an era are always more interesting than still water. Rather than clinging to a single foothold, she would rather leap with the times, joining in the dangerous game of takeoffs and landings.
So where is the butterfly that first fluttered its wings?
If you want to hide a leaf, the best place is a forest. If you want to hide a brilliant mind, the best place is Laplace. Yes, it is the temple of science—but the science it commands cannot answer the great questions of its era. That alone can trigger a collapse of faith. Fortunately, she was never attached to any of it.
When neat theories crumble with the era, a butterfly stirs its wings among the rubble, flying into endless chaos.
Additive Manufacture Designs
"Good-Job Badge"
A tracker designed for Eagle.
Better come up with a reason to give it to her—wouldn't want this excellent remote assistant getting lost in the "Storm." Then again, when has a scout ever turned down a badge?
"Tower of Babel" Translation Box
A multilingual collision translator, Critter-speech included. Give it enough raw material and it'll invent a new language.
The initial version has been sent to Comala Prison in Ushuaia. The all-knowing advisor within is currently verifying the validity of the new language.
Auto-Playing Rifle
Follows the beat automatically—no musical training required. Elegant rhythm, full of beauty.
Detachable, equipped with an Incantation Radiance tracking system.
I know you'll see this note, Timekeeper. Sneaking into concerts is something of a tradition at Institutum Lorentz. Perhaps you'd like a ticket?
Sense of Humor
Pandora Wilson: "Killer." Genius researcher from Institutum Lorentz. The woman behind the cases. What can I say? Every magazine loves a label that gets people talking.
Lorentz Butterfly: Perhaps, as Ms. Recoleta suggests, these labels give UTTU a touch of counterculture.
Pandora Wilson: Ms. Butterfly, has anyone ever told you that you have a very unique sense of humor?
Lorentz Butterfly: Comedy is just one of my little hobbies. "It's just a joke" has served me rather well over the years.
Lorentz Butterfly: Deny a comedian like me her jokes, and the consequences could be severe.
Pandora Wilson: Such as?
Lorentz Butterfly: When a sense of humor has nowhere to go, misery piles up. And eventually ... the joke falls on you.

Skills
3The Primer's Flutter
Incantation 11-target attack. Deals 800% Mental DMG. Before attacking, inflicts 3 stacks of [Burn] on the target. After hitting the target, deals an additional (DMG dealt by allied incantations to the target this round x6%) [Static Genesis DMG], increased by 1% for every 100 points of Lingering Glow, counting up to 600 points (triggers up to 10 times per round).
Burn 60 milligrams of primer, trigger the flutter of a butterfly's wings, and the future is forever changed.
StarsChaos Criteria
Incantation 2Mass buff. Gains [The Igniting Wingbeat] for 3 rounds and grants the same effect to all other [Lingering Glow] allies.
When period-doubling bifurcation occurs, the system loses order and begins its descent into chaos.
StarsThe Unstable Dynamical System
UltimateSelf buff. Gains [Continuous Action I] for 1 round. Before casting, selects 1 basic incantation in the Spelldock to print. After casting, prints 3 [Precast Incantation] duplicates, which are generated and rewritten with [Fractal Dimension] at the start of the next round.
Perhaps chaos is the most natural interpretation and resistance to fate.
Insight passives
4Nonperiodic Flow
PassiveAccumulates [Lingering Glow] (mutually exclusive with [Bloodtithe]) whenever an enemy is inflicted with [Burn] or [Halo].
Nonperiodic Flow
Insight IRight before the AP Area resolves, each of Lorentz Butterfly's basic incantations gains rank +1 for every other basic incantation of the same type in the AP Area.
Nonperiodic Flow II
Insight IICritical Rate +10% when entering battle.
Nonperiodic Flow III
Insight IIIWhen entering battle, gains Moxie +2. At the end of the round, [Lingering Glow] allies who did not cast an Ultimate this round gain Moxie +1 (Lorentz Butterfly gains an additional Moxie +1). [Lingering Glow] allies' Ultimates do not take up the allied Incantation Draw Limit. All enemies' [Burn] stack limits increase by 5. When at least 3 [Lingering Glow] allies are present, the Burn stack limits additionally increase by 15. When 1/2/3 [Lingering Glow] allies are present: at the start of the round, for every 100 points of [Lingering Glow] (counting up to 600 points), grants DMG Bonus +2.5%/5%/15% and Incantation Might +1%/2%/6% to all allies for 1 round.

6- Halo
- Healing Taken -25% (unstackable). At the end of the round, takes (the inflicter's ATK x4%) Genesis DMG (stackable up to 40 times, multiple stacks of Halo are regarded as 1 [Neg Status], removes 50% of the stacks when triggered).
- Fractal Dimension
- Rewrites the incantation's surface. When the incantation is played, it does not cost AP and does not grant Moxie. The incantation cannot be merged. (Does not stack with other effects that rewrite the incantation's surface.)
- Static Genesis DMG
- This type of Genesis DMG is not affected by relevant stat bonuses.
- Continuous Action I
- AP +1.
- Precast Incantation
- A [Precast Incantation] is regarded as an incantation of the same name. At the end of the round, all unused [Precast Incantation] are removed.
- The Igniting Wingbeat
- When attacking, additionally inflicts 1 stack of [Burn].
