Arclight
Searly game support
supportsp_generatordpselectric
Arclight stands out as a top pick because her low-cooldown Combo Skill feeds a steady stream of SP back into the team. That strength comes with a caveat: the Combo Skill only fires on Electrification, so she needs a partner capable of applying Electric Infliction, since her own kit only provides it through her Ultimate. Her Electric DMG buff from the Battle Skill is gated behind every third Electrification use, which drains SP, so it is better treated as a bonus rather than her main function.
The early game build keeps Arclight functional before endgame gear is farmed. She keeps the same Thermite Cutter, which is obtainable early through the New Horizons banner weapon selector, and wears full Mordvolt Insulation to pile on Intellect so her Wildland Trekker buff still contributes meaningfully. Her role is unchanged — an SP battery for Electric teams that also chips in damage — but the raw stat line is weaker than the endgame Frontiers setup. Once better pieces are available, transition the gear to Frontiers while keeping the weapon.
Insights
Core Mechanics
- Peal of Thunder is a low-cooldown Combo Skill that damages enemies and refunds SP, but only triggers when an enemy is Electrified or when that Electrification is consumed.
- Tempestuous Arc blinks to the target for two slashes, and consumes active Electrification for an extra Electric hit plus SP recovery.
- Exploding Blitz is her only self-contained source of Electric Infliction, and it converts existing Infliction into forced Electrification after a short delay.
- Because she has no innate Electric Infliction outside the Ultimate, she must be paired with another Electric applier to keep her Combo Skill firing.
Scaling
- Intellect directly scales the Wildland Trekker teamwide Electric DMG buff, so stacking it improves her support output as she is invested into.
- Ultimate Gain is the other key growth stat, giving her more frequent Exploding Blitz casts for additional Infliction or Electrification windows.
- Early on she functions mostly as an SP battery; the Wildland Trekker buff only becomes meaningful once Intellect totals climb.
Team Role
Arclight slots into Electric-focused compositions as an SP engine and secondary damage dealer rather than a pure buffer. Her Combo Skill has a very short cooldown and feeds SP to the whole squad whenever Electrification is present, so she pairs best with at least one other operator who can inflict Electric. The rotation revolves around stacking Combo Skill casts: fire Peal of Thunder first, then use Tempestuous Arc to retrigger it, and time Exploding Blitz on an already-Inflicted target so the delay covers both the Infliction and the resulting Electrification. Teammates like Zhuang Fangyi can exploit either the raw Infliction or the Electrification depending on what their own kit wants. Her damage is largely off-field, so she is usually played as a support anchor while another character holds the field.

Explanation
Thermite Cutter is retained here because it is available early via the New Horizons banner weapon selector and still grants her a teamwide attack buff.
Mordvolt Insulation is picked over other early sets purely for the Intellect it stacks — nothing else in the early pool raises her Talent's buff as efficiently.
The set's Arts DMG bonus while above 80% HP is a secondary perk that occasionally helps her own Electric output, but Intellect is the reason to run it.
This build is a stepping stone: keep the same weapon and swap the gear set to Frontiers once the pieces are available.
Notes
- Mordvolt Insulation provides a large flat Intellect boost, which is the cheapest way to strengthen her Wildland Trekker buff early on.
- The same Thermite Cutter carries over from the support build, so no weapon swap is needed when transitioning.
- Thermite Cutter can be picked up from the weapon selector in the New Horizons banner, making this setup accessible from the start.
