Arclight Best Build Guide (2026): Skills, Weapons, Gear & Teams in Arknights: Endfield

Arclight is one of the best Electric support units in Arknights: Endfield.

Arclight is not a main DPS.
Arclight’s value comes from:

• SP recovery

• Electrification interaction

• faster team rotations

• stronger Electric team consistency

If your team is built around Electrification, Arclight is a high-value pick.
If your team is not built around Electric status loops, Arclight becomes much less impressive.

How Arclight Actually Works

Most players misunderstand Arclight.

Arclight is not a damage-focused unit.
Arclight is a tempo support.

Real job:

• establish or consume Electrification

• trigger Combo Skill often

• recover SP

• let your main DPS rotate faster

Simple loop:

1. apply Electric Infliction / Electrification

2. use Tempestuous Arc

3. trigger Peal of Thunder

4. recover SP

5. pass tempo back to your carry

Key takeaway: Arclight makes strong Electric teams smoother and faster.

Best Teams for Arclight

Best Team

Perlica + Arclight + Gilberta + Zhuang Fangyi

Why this team works:

• Perlica provides Electrification

• Arclight converts that into SP and faster rotations

• Gilberta buffs team damage and adds crowd control

• Zhuang Fangyi provides heavy Electric Infliction and triggers Arclight’s Combo Skill very frequently

Icy Veins currently lists this team directly, and the page changelog states it was updated for Zhuang Fangyi’s release on April 18, 2026.

Key takeaway: Perlica builds the status foundation. Arclight drives the engine. Gilberta stabilizes and buffs. Zhuang Fangyi converts the setup into major damage.

Secondary Team

Arclight + Perlica + Antal + Avywenna

Why it works:

• still uses Electrification well

• keeps Arclight inside a proper mono-Electric shell

• remains a valid alternative if you are not running Zhuang Fangyi

Key takeaway: This is still a good Electric team, but the Zhuang Fangyi team has the stronger headline value right now.

Advanced Tips

Core points:

• do not use Tempestuous Arc without Electrification unless you must

• keep Electrification available as often as possible

• value Intellect more than many players expect

• use Frontiers to maximize team buff uptime

• treat Arclight as a rotation engine, not a carry

Key takeaway: The better your team loop is, the better Arclight becomes.

Is Arclight Worth Building?

Worth building if:

• you play Electric teams

• you want better SP economy

• you want smoother team rotations

• you are using Zhuang Fangyi or other Electric-focused units

Less worth building if:

• your team has weak Electrification support

• you want a solo carry

• you prefer direct DPS value

Final verdict:

Yes, Arclight is worth building for real Electric teams.
No, Arclight is not a good investment if you expect a standalone carry.
