Who Should Use Starlight Engine

Ranks and notes come from each Agent's build guide on Zenless Builds.

Evelyn
EvelynPick #4 of 6 · S5
The go-to A-Rank choice, beating even the event options when managed well: a sizeable combat ATK bonus, though it needs refreshing with a Quick Assist mid-combo at the right moments.
Sigrid de L'Azur
Sigrid de L'AzurPick #4 of 6 · S5
The craftable F2P option, but far behind the choices above: its bonus is modest and needs Quick Assists to stay up during Stun. Her Dodge Counter is also an Unbridled Spear attack, which helps a little.
Ye Shunguang
Ye ShunguangPick #4 of 5 · S5
The best A-Rank option: her Entry Skill counts as a Quick Assist, so nearly every Enlightened Mind state gets the ATK buff. Quick Assist into her before Ultimates, since those bypass the effect.
Nekomata
NekomataPick #5 of 5 · S5
The best A-Rank pick: its ATK buff after Dodge Counters can stay up almost the whole fight, since she can Dodge Counter even during Stun. If you plan to use her enhanced counter late, activate the buff before the Stun starts.
Soldier 0 - Anby
Soldier 0 - AnbyPick #5 of 6 · S5
The F2P option for any Attack Agent, with flat ATK% plus an ATK buff after a Dodge Counter or Quick Assist. Her Stun-window burst doesn't naturally include either, so you have to refresh it deliberately.
Zhu Yuan
Zhu YuanPick #5 of 6 · S5
A solid free-to-play pick for any Attack Agent: flat ATK% plus extra ATK after a Dodge Counter or Quick Assist, which is easy to trigger with a Support on the team.
Ellen
EllenPick #6 of 6 · S5
A solid free-to-play pick for Attack Agents: flat ATK% plus extra ATK after a Dodge Counter or Quick Assist, easy to trigger with a Support on the team.
Harumasa
HarumasaPick #6 of 6 · S5
The F2P option for any Attack Agent: flat ATK% plus an ATK buff after a Dodge Counter or Quick Assist. With a Support on the team, one Quick Assist before the combo and one refresh halfway through are enough.
Soldier 11
Soldier 11Pick #6 of 6 · S5
A dependable free option for Attack Agents: ATK% main stat plus an ATK buff after Dodge Counters or Quick Assists.
Anton
AntonPick #6 of 6 · S5
A dependable free option with an ATK% main stat plus an ATK buff after Dodge Counters or Quick Assists. The buff is easy to maintain with a Support in the team. Marcato Desire also works. His signature Drill Rig - Red Axis is only worth it if Anton truly needs the Energy Regen.
Billy
BillyPick #6 of 6 · S5
The best craftable engine. Its ATK buff after Dodge Counters stays up almost permanently outside Stun, but you need Quick Assists to keep it through a full Stun. Marcato Desire is another good free option.
Corin
CorinPick #6 of 6 · S5
A dependable free option for any Attack Agent. It has an ATK% main stat plus an ATK buff after Dodge Counters or Quick Assists.
