Arclight Lore
"I am Ekut. Callsign Arclight. I am not a trained weaver of words, but I wish you well and may you flow like a rising river, Endfielders."
Arclight is a Songseeker who joined Endfield Industries at the recommendation of Aldertone Orisha. She now serves as a field operator and a technical consultant for machinery and vehicles.
No one roaming the wildlands could escape the grip of starvation and disasters, no matter how clever or capable they may think themselves to be. Misfortune struck Arclight hard. The wildlands consumed her entire family, leaving her the only survivor. However, fortune also smiled upon her when a group of Hannabit Circuit Songseekers found and saved her from the brink of death.
The Hannabit Circuit accepted her. There, she quickly learned how to survive in a harsh landscape and follow the example of the Paragons from hannas to help those in need. Today, she roams the wildlands to teach more souls the way of surviving in the unforgiving world of Talos-II.
Arclight may come across as cold and brusque at first, but her minimalist philosophy has proven exceptionally effective for surviving in the wildlands.

Collaboration Disclaimer
For Arknights: Endfield we worked alongside Guobafield (Guoba Certified) for some calculations. Calculations not appearing in his videos, as well as any other content (like comments on Weapons), are our own.
Arclight Best Weapons
The percentages show the performance of the weapon based on calculations, but in some cases, some Weapons might provide additional QOL that can't be quantified and it would push that weapon ahead of others in the priority (and in those cases, we would put that weapon higher).
The solo percentage shows how the weapon impacts Arclight performance if you look at their damage in the vacuum, while the team percentage shows the impact of the weapon when taking into account full team, including buffs etc.
Stat 1 Boost - 9/9
Will: +156
Stat 2 Boost - 9/9
Attack: +39.00%
Passive Boost - 4/9
Attack: +16.00%
Arclight's best weapon choice when factoring in the team-based buffs it provides, but not the strongest for her own personal damage due to the main attribute being WILL, a stat she cannot use. Fortunately, the other passives are all fantastic, which, when combined with the Weapon Ekill, that she can easily maintain thanks to her spammable Combo Skill, makes this the weapon to target when playing her in most compositions.
Stat 1 Boost - 9/9
Agility: +124
Stat 2 Boost - 9/9
Attack: +31.20%
Passive Boost - 9/9
Sec. Attribute: +14.00%
A 5-star alternative to Thermite Cutter, which works very similarly, but instead of granting generic ATK% instead provides Physical and Electric DMG% when Arclight recovers SP, making it more specific, and in a lot of cases weaker even in Electric/Physical teams, due to DMG% being less desirable than ATK%. One redeeming quality of this weapon though, is that its passives are much better suited to Arclight’s kit than Thermite Cutter, thanks to it having Agility.
Stat 1 Boost - 9/9
Agility: +124
Stat 2 Boost - 9/9
Attack: +31.20%
Passive Boost - 9/9
Sec. Attribute: +14.00%
If you're less interested in building your Arclight to support the team, Twelve Questions is her best personal damage option, although it doesn't beat out Thermite Cutter or OBJ by much.
Stat 1 Boost - 9/9
Agility: +132
Stat 2 Boost - 9/9
Physical DMG Bonus: +43.30%
Passive Boost - 4/9
Attack: +16.00%
If you have none of the options above available, you can use Eminent Repute as a stat stick thanks to its strong passives for Arclight. Keep in mind though, she cannot activate its Weapon Effect.
Stat 1 Boost - 9/9
Agility: +124
Stat 2 Boost - 9/9
Physical DMG Bonus: +34.70%
Passive Boost - 9/9
Attack: +14.00%
Another stat stick Arclight can use for its passive stats, even though she can't activate its Weapon Effect. Not as strong as Eminent Repute, but something to equip if you have nothing else.
Stat 1 Boost - 9/9
Agility: +93
Stat 2 Boost - 9/9
Physical DMG Bonus: +26.00%
Passive Boost - 9/9
Last resort option if you're lacking any of the choices above. Has the correct passive stats, but all at much lower base values, setting it significantly behind all other choices.
Arclight Best Gear Set
The solo percentage shows how the set and gear impact Arclight performance if you look at their damage in the vacuum, while the team percentage shows the impact when taking into account full team, including buffs etc.
Combo Skill CDR +15%. When the wearer recovers SP with a skill, the team gains DMG +16% for 12s. This effect cannot stack.
Description
Best set for Arclight in most teams after factoring in the buffs it provides to her teammates, even if wearing it results in a major reduction of her own personal damage. What makes it so strong is the 3P Set Bonus, which grants a DMG% buff to the whole team every time Arclight generates SP, which, thanks to her Combo Skill, is all the time, meaning a permanent boost.

Attack +15%. When the wearer casts a combo skill, gain 1 stack of Bonekrushing Smash that grants DMG +30% to the next battle skill cast. Bonekrushing Smash can stack 2 time(s).
Description
If you're playing Arclight in a more damage-focused role and are fine giving up the team-based benefits of Frontiers, Bonekrusha will grant her more personal damage thanks to its damage-focused 3P Set Bonus and superior damage choices on gear pieces.

Arclight Best Gear Pieces
Keep in mind that the gear pieces below are being compared against having nothing equipped on the character at all. This means that in some cases, when you include Weapons, other pieces, outside buffs etc, the values of some pieces may change. For more accurate information, check the section above where we picked the best combination when you look at all pieces equipped.
Pieces marked with a star* can perform better than listed - this applies to:
- Ult gain efficiency pieces, granting new Ultimate breakpoints,
- Arts Intensity boosting the efficacy of Electrification, Corrosion and Breach, rising overall team output even if personal damage is less impressive.
Arclight Calculations
In this section we're showing the team setup used for the above calculations as well as the damage split for Arclight based on where it comes from. The setup isn't always best in slot for each character and also please keep in mind that with different team members, Weapons, and Gear, the calculations will change.

Teams and Synergies
Arclight Best Synergies
- Applies Electrification for free with her Combo skill, triggering Arclight's Combo skill once. Electrification can then be consumed by her Battle Skill, which triggers her Combo again, positioning Perlica as a free activator for Arclight
- Perlica has outstanding supportive weapon choices, which nicely buff Arclight and the rest of the team
- Arclight's own supportive weapon and sets buff Perlica back, allowing the two to buff each other in order to both deal more damage
- Arclight consumes minimal SP herself and generates some back, freeing it up in some teams for Perlica to use on her Battle Skill to gain more damage
- Avywenna doesn't consume Electric Infliction stacks or Electrification like most carries might, leaving them all for Arclight to consume herself
- Avywenna benefits from ArcLight's fantastic, supportive weapon and gear bonuses
- Avywenna applies Electric Susceptibility to enemies boost the damage Arclight does as well
- Avywenna doesn't require as much SP as other main damage dealers, leaving more for Arclight to use on Battle Skills if she has Electrification to consume
- Antal applies Electric Susceptibility and Amp with his abilities, boosting Arclight damage potential signfiicantly
- Antal doesn't require much SP to function, leaving more to Arclight's Battle Skills when Electrification is available
- Antal can help stack up high stack sizes of Electric Infliction, which can then be consumed by Arclight's Ultimate for large Electrication damage taken debuffs on high-priority enemies
- Antal provides ArcLight's fantastic damage increases from his great supportive weapon and gear bonuses
- Brings healing to Arclight and her team
- Wulfgard can take over the Electrification consumption role of the team to deal massive damage, while Arclight still gets to trigger her Combo Skill
- Wulfgard benefits from Arclight's fantastic, supportive weapon and gear bonuses
-
