Arclight
Sendgame support
supportsp_generationteam_buffelectricvanguard
Arclight earns an S rating because her short-cooldown Combo Skill feeds the squad a steady stream of SP, and she can even retrigger it with her Ultimate for rapid double casts. The catch is that she needs external Electrification to keep that loop running, so she only truly shines in Electric-focused lineups built around another inflictor.
This is Arclight's endgame support setup, built to make her the SP engine of an Electric team while quietly raising everyone's damage. Thermite Cutter provides a team-wide attack buff, and the Frontiers set converts her SP generation into an additional damage boost for the squad, with the set's Combo Skill cooldown reduction letting her fire Peal of Thunder more often. The Redeemer Seal off-piece tops things off with Intellect and Ultimate Gain, so her Wildland Trekker buff hits harder and Exploding Blitz is available more frequently as a fresh Infliction source. Because Intellect drives her Talent's Electric DMG bonus, every Intellect roll on the gear is a direct upgrade to the team's output rather than to her own damage.
Insights
Core Mechanics
- Peal of Thunder is her Combo Skill: a low-cooldown blink-and-slash that restores SP, fired whenever an enemy gains Electrification or has theirs consumed.
- Exploding Blitz dashes forward, applies Electric Infliction along the path, then converts an existing Infliction into forced Electrification.
- Wildland Trekker only pays out on every third consumption of Electrification through Tempestuous Arc, so her Electric DMG amp is a side bonus rather than her main function.
Scaling
- Early on she is mostly an SP battery — her personal damage stays modest no matter how much you invest in her.
- Her team buff scales off Intellect, so every point of Intellect from weapons and gear translates into more Electric DMG for the whole squad.
- She is heavily team dependent: without a second Electric Infliction source only her Ultimate can start the Combo Skill loop.
Team Role
Arclight slots into squads as a support-style Vanguard whose job is keeping everyone else's skills available. Her Combo Skill comes off cooldown quickly and hands SP back to the team, so she thrives in rotations where allies want to spam Battle Skills and Ultimates. Because her only personal source of Electric Infliction sits on her Ultimate, she needs at least one other operator who can apply Infliction or Electrification to keep Peal of Thunder firing — otherwise her value collapses. Position her in Electric-centric compositions where a teammate opens with Infliction, then layer her Combo Skill and Ultimate around that window to chain multiple casts. She is also a flexible enabler for characters that care about the Infliction-versus-Electrification timing, since her Ultimate applies Infliction first and converts it a beat later, letting partners consume either state.

Explanation
Thermite Cutter takes the top slot because it grants the entire team an attack buff and is easy to secure from the weapon selector on the New Horizons banner.
OBJ Edge of Lightness is a workable substitute, but its buffs are narrower and only lift Heat and Electric damage.
Fortmaker functions as a pure stat stick for Intellect and Ultimate Gain; it offers none of the team-wide buffs the other two weapons bring.
The Frontiers set is chosen because restoring SP with a skill hands the team a damage buff, and the set also shortens her Combo Skill cooldown so she cycles faster.
Redeemer Seal fills the remaining slot for its Intellect and Ultimate Gain, boosting both her Talent buff and her access to a second Infliction source.
Notes
- Frontiers plus a Redeemer Seal off-piece turns her SP recovery into a squad-wide damage buff.
- The Intellect stacked on these pieces feeds directly into her Wildland Trekker Electric DMG amp.
- Ultimate Gain on the off-piece keeps Exploding Blitz coming back sooner for extra Infliction.
