  • Arclight Overview

Arclight is an Electric Vanguard Operator focused on generating SP while interacting with Electrification to support her team. Her playstyle revolves around triggering and consuming Electrification through her skills. Then, she uses these interactions to repeatedly activate her Combo skill, generating large amounts of SP and enabling continuous skill rotations. She performs best in teams that can consistently apply Electrification, allowing her to maintain her setup and fully take advantage of her SP generation and passive Electric damage buff for strong, coordinated burst output.

Arclight Skill Priority

SkillPriorityReason

Seek and Hunt

(Basic Attack)

Lowest priority. Can be left unupgraded since Arclight is mainly used off-field.

Tempestuous Arc

(Battle Skill)

★★★Leveled second for improved SP recovery when consuming Electrification, but can be left at moderate levels.

Peal of Thunder

(Combo Skill)

★★★★Top priority. Core skill that generates SP and drives her entire rotation.

Exploding Blitz

(Ultimate)

★★Primarily used to apply and convert Electrification to trigger her Combo. Can be leveled for damage, but not a priority.

Arclight Best Weapons and Essence Priority

Arclight scales mainly with Agility, with Intellect as a secondary stat that enhances her teamwide Electric damage buff. Her kit focuses on SP generation and team support, so weapon choices should prioritize teamwide buffs and consistency over personal damage.

Arclight's best weapon, Thermite Cutter, is the strongest option as it provides a valuable ATK% team buff. The OBJ Edge of Lightness is a strong alternative, offering solid stats. Twelve Questions provides strong stats and improves her personal damage, along with a Secondary Attribute bonus that benefits her Talent, but it is generally less preferred since it does not significantly boost overall team performance compared to other options.

Arclight Best Gear Set

For the early game, Arclight can use any gear that provides Agility or Intellect, as these stats improve her damage and Electric damage buff, making her kit more consistent. When building the best gear for Arclight, transitioning into the Frontiers set is ideal. It synergizes with her kit by increasing team damage whenever she generates SP, while its pieces also grant Secondary Attribute%, which further enhances her Wildland Trekker talent. This setup makes it easier to maintain strong rotation uptime and overall team performance throughout fights.

Arclight Best Teams

For Arclight’s best teams, Arclight works best in teams that can consistently apply Electrification and take advantage of her SP generation and Electric damage buff. She benefits most from teammates that can reliably trigger Electrification, provide strong burst damage, and utilize the increased Electric damage from her passive. Arclight prefers structured rotations and a consistent setup to fully capitalize on her Combo loop, SP generation, and timed buff activation for coordinated burst windows.

P4: Aldertone's Teaching
  • Rating - ★★★ (Good)
  • Potential Effect - Ultimate Exploding Blitz improved: Ultimate Energy cost -15%.
  • Reason - Reduces her Ultimate cost, improving rotation consistency and accessibility. This allows for more frequent Electrification, Combo triggers, and SP generation, making her overall gameplay smoother and more efficient.
P5: Servant of the Wildlands
  • Rating - ★★★ (Good)
  • Potential Effect - Talent Wildland Trekker improved: Trigger requirement is reduced to 2 time(s).
  • Reason - Her most impactful upgrade. Reduces the requirement for activating Wildland Trekker, making her buff easier to maintain and allowing more flexible rotations. This significantly improves her team support consistency and overall value.

Conclusion

Arclight excels as an excellent battery, providing steady SP generation while amplifying Electric damage through her passive. By interacting with Electrification, she enables smoother rotations and more frequent skill usage across the team. She is most effective in Electric-focused teams that can consistently trigger and consume Electrification, allowing her to maintain strong uptime and support coordinated burst windows.
