Attributes
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.

Recommended 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 - 9/9Will: +156Stat 2 Boost - 9/9Attack: +39.00%Passive Boost - 4/9Attack: +16.00%After the wielder's skill recovers SP or grants a Link state, the entire team gains ATK +8% for 20s. Max stacks for effects of the same name: 2. Duration of each stack counted separately.
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 - 9/9Agility: +124Stat 2 Boost - 9/9Attack: +31.20%Passive Boost - 9/9Sec. Attribute: +14.00%After the wielder recovers SP by their own skill, the entire team gains Heat DMG dealt and Electric DMG dealt +8.4% for 20s. Max stacks for effects of the same name: 3. Duration of each stack is counted separately.
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 Arclightâs kit than Thermite Cutter, thanks to it having Agility.
Stat 1 Boost - 9/9Agility: +124Stat 2 Boost - 9/9Attack: +31.20%Passive Boost - 9/9Sec. Attribute: +14.00%After the wielder consumes an Arts Reaction, ATK +21% for 20s. Max stacks for effects of the same name: 2. Duration of each stack is counted separately.
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 - 9/9Main Attribute: +132Stat 2 Boost - 9/9Physical DMG Bonus: +43.30%Passive Boost - 4/9Attack: +16.00%After the wielder consumes Vulnerability stack(s), ATK +[8% + 4% x Stacks Consumed] while other Operators in the team gain half of this buff for 20s. Effects of the same name cannot stack.
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 - 9/9Agility: +124Stat 2 Boost - 9/9Physical DMG Bonus: +34.70%Passive Boost - 9/9Attack: +14.00%After the wielder deals a Physical Status, ATK +21% for 20s. Max stacks for effects of the same name: 2. Duration of each stack is counted separately. Effect only triggers once every 0.1s.
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 - 9/9Agility: +93Stat 2 Boost - 9/9Physical DMG Bonus: +26.00%Passive Boost - 9/9After the wielder's Battle Skill hits the enemy, ATK +33.6% for 20s. Effects of the same name cannot stack.
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.
Gear Sets
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.Between the pre-release version of Endfield and 1.0, there was some major balance adjustments. The two major ones that have affected some of the %'s on a few of our build guides are the major buff to Physical Status effects (namely Breach and Crush), and the the nerf to Bonus DMG% vs Staggered gear pieces. All other character buffs/nerfs have also now been factored in but they have minimal impact on %'s. Note - no recommendations have changed as a result of this update, only the relative differences between weapons, sets and pieces was affected.
Combo Skill CDR +15%. When the wearer recovers SP with a skill, the team gains DMG +16% for 12s. This effect cannot stack.
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 strong is the 3P bonus, which grants a DMG% buff to the whole team almost permanently thanks to Arclight's Combo spam. The other benefit of this set is its focus on boosting Secondary Attributes, something which may or may not be impactful to your Arclight depending on how optimized your gameplay is. In teams where you align her talent Wildland Trekker, with your team's burst, investing heavily into Intellect makes sense, but if you're not specifically timing it, boosting Arclight's own damage can be stronger.
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).
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 and superior damage choices on gear pieces.Note: To get the listed results out of this set, you'll need to make optimal use of Stagger windows to take advantage of both kits having DMG% vs Stagger. If you can't, this setâs performance will notably drop.
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.
