Arclight Build Guide

Avywenna Perlica Arclight Antal

Mono-Electric Team that uses Arclight and Antal to amplify the team Electric DMG. Make sure to trigger Avywenna Combo Skill before consuming Electrification from enemies.

Avywenna Perlica Arclight Ardelia

Another variation of the team above. Ardelia provides Corrosion and Physical/Arts Susceptibility. She’s not specialized as Antal, but Arclight deals a lot of Physical Damage and can benefit from Ardelia too.

Weapons

• Best-in-Slot: Twelve Questions
• Alt: Thermite Cutter
• Alt: OBJ Edge of Lightness

Arclight’s Signature gives a lot of great stats but it’s only to increase Arclight’s own damage potential.

Thermite Cutter increases the ATK of your team whenever Arclight recovers SP. The weapon stats are not great for her damage, but it increases the team’s overall damage.

OBJ Edge of Lightness is similar to Twelve Questions, but with a team-wide Electric/Heat Buff.

Gear

• Gear Set: Frontiers
• Armor: Frontiers Armor T2
• Gloves: Frontiers Blight RES Gloves
• Kit 1: Frontiers Extra O2 Tube
• Kit 2: Frontiers Extra O2 Tube

Frontiers is the Vanguard Set, so it’s an obvious pick for Arclight.

• Gear Set: Bonekrusha
• Armor: Bonekrusha Heavy Armor
• Gloves: Frontiers Blight RES Gloves
• Kit 1: Bonekrusha Mask T1
• Kit 2: Bonekrusha Mask T1

Bonekrusha trades Team Utility for more personal damage.

Battle Skill > Combo Skill > Ultimate > Basic Attack

Focus on her Battle Skill first to increase the SP recovery when consuming Electrification. Everything else is just for damage.

• P1 Child of the Storm
• P2 Speed Battler
• P3 Hanna
• P4 Aldertone's Teachings
• P5 Servant of the Wildlands

Arclight Potentials focus on her SP Generation and Team Utility, providing increased damage through her Combat Talent. The most noticeable one is Potential 5, as it reduces the number of times you need to consume Electrification from enemies to activate her Combat Talent.

Keep in mind that vertically investing in Arknights Endfield is not recommended and you should treat these as a bonus damage/utility for your Operator.

Arclight wants some source of Electric Inflictions on the team, as she requires enemies to suffer Electrification but only her Ultimate can apply Electric Inflictions. And you don’t want to use her Ultimate to apply Inflictions, you want it to consume Electric Inflictions and trigger Electrification on enemies.

Every time you trigger Electrification or consume Electrification from enemies you can use her Battle Skill, which generates some SP and has a really low cooldown. Her Battle Skill can consume Electrification to deal increased damage and also recover SP, so make sure that your Combo Skill is available before using her Battle Skill.

Her Combat Talent also helps other Electric Units to deal increased damage, but to activate it she needs to consume multiple Electrification from enemies. So depending on your teammates, managing Electrification on enemies will be really important. For example, Avywenna’s Combo Skill requires Final Strikes against enemies under Electric Infliction or Electrification, so consuming Electrification can destroy your Avywenna Rotation.

Arclight will release on January 22nd, 2026 along with the release of Arknights: Endfield.

Arclight is a Standard Operator, meaning they are permanently available through the gacha system.
