Playstyle Overview
Starlight - Billy is a Physical Rupture DPS who deals Sheer DMG based on Sheer Force (converted from HP) and ignores enemy DEF. He spends HP on Special Attack: Drive Suppression, which flows into a free Cool Wheelie that builds Determination, then heals back through Basic Attacks and Dodge Counters.
At 100 Determination, you hold Basic Attack for Full-Throttle Starlight. During a Stun, unload it with Chain Attacks, EX Special Attacks and his Ultimate, which his Additional Ability boosts by up to 40%. He has high burst and easy substats, since his CRIT DMG is already saturated. In return, he relies on Dialyn and Lucia, is costly to invest in and has long animations.

Always prioritize CRIT Rate to 90–100% in combat. Billy already gets up to 90% CRIT DMG from his Core Passive plus team buffs, so the gap between crit and non-crit hits is huge. After that, CRIT DMG and HP% are about equal. An HP% Disc 4 is only worth considering against bosses with CRIT DMG-boosting mechanics. Disc 5 should be Physical DMG since Billy has few Physical DMG sources.

Chain Attack - ›
Special Attack - ›
Basic Attack - ›
Assist - ›
Dodge
His Core Skill grants CRIT Rate, Sheer Force and the 90% CRIT DMG buff, so level it first. Billy's damage is spread over his Ultimate/Chain Attack, EX Special Attacks and enhanced Basic Attack, so all three need high levels. Chain Attack and Special Attack get a slight edge. Assist and Dodge come last.

Mindscape Cinema
Which Mindscapes Are Worth It?
M1 is the most valuable, on par with or better than limited Supports' M1s. M2 is a good stopping point since it makes combos tighter and much stronger. M4 is only a stepping stone (about 3–5%), while M6 adds a meaningful boost to his Ultimate and enhanced Basic Attack.
- M1Billy gets an extra 60 Adrenaline on entering combat and ignores 18% Physical RES for 45s after an EX Special Attack hits. He often deals around 95% of the team's damage, so this matches a Support's M1.
- M2+50% DMG to Full-Throttle Starlight, Cool Wheelie and his Ultimate, plus Turbocharged for instant Cool Wheelies with extra CRIT DMG. Your Stun combos get tighter and reliably fit 2 Full-Throttle Starlights while needing only 60 Adrenaline.
- M4Billy gains up to 16% CRIT DMG after Drive Suppression and heals himself while off-field below 35% HP. His CRIT DMG is already saturated, so it's only about a 3–5% damage gain.
- M6+18% Sheer DMG for his Ultimate and Full-Throttle Starlight, plus Brilliant Starlight stacks consumed for extra Sheer Force-based hits. With Dialyn, you can get up to 8 of these hits per Stun.
M1Heroic EntranceRecommended

"I might be good at shouting heroic lines, but I can't really call myself a hero yet..."
"But I'll follow their example and stand up front to protect everyone!"
M2Wasteland AutomatonRecommended
Increases the DMG dealt by Basic Attack: Full-Throttle Starlight, EX Special Attack: Cool Wheelie, and Ultimate: Starlight Knight Flying Kick by 50%.
Activating EX Special Attack: Rocking Footwork, EX Special Attack: High-Traction Wheels, or hitting a Stunned enemy with Special Attack: Drive Suppression grants the Turbocharged effect: Special Attack: Drive Suppression consumes this effect to immediately follow up with EX Special Attack: Cool Wheelie, and increases that instance's CRIT DMG by 50%. Only 1 stack of Turbocharged can be held.
There's no shortage of sharpshooters in the Outer Ring, but keeping perfect aim on a speeding bike is what defines a real ace.
"Ballistic calculations and mechanical fingers? Of course they help..."
"But the real reason I'm dead-on every time is because... the Starlight chose me!"
M3Knight's Chivalry
Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2
What does it really mean to be a Starlight Knight? Never backing down and standing up for the weak? Sacrifice, justice, compassion, honor?
"Do what is right..."
"And don't compromise on what's not cool!"
"That's why I'll never abandon my companions!"
M4Flames of JusticeRecommended
While in combat, each use of Special Attack: Drive Suppression increases Starlight - Billy's CRIT DMG by 8%, stacking up to 2 times, and lasting 45s. Repeated triggers reset the duration.

"The most courageous dreams are the ones only kids dare to believe in, right?"
"Then I, Starlight - Billy, will protect those ridiculed dreams!"
M5Radiant Armaments
Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2
You need a dazzling outfit to look like a real hero... it makes the whole thing pretty inconvenient.
"I'm not strong because of larger-caliber weapons or higher-power components!"
"My true weapon... is the endless starlight!"
M6Starlight KnightRecommended
Ultimate: Starlight Knight Flying Kick and Basic Attack: Full-Throttle Starlight's Sheer DMG increases by 18%.
Landing the 4th hit of Basic Attack: Knight's Technique, EX Special Attack: Cool Wheelie, or Chain Attack: Knight's Swagger grants 1 stack of Brilliant Starlight, stacking up to 6 times, and gaining at most 1 stack per skill use.

Those who always believe in hope will, in the end, become someone else's hope.
