Arclight
Searly game support
supportsp_generatorelectric_buff
Arclight earns an S tier because her low-cooldown Combo Skill generates a large amount of SP for the team. However, she heavily depends on Electrification to trigger that loop, and her only personal source of Electrification is her Ultimate. Her teamwide Electric DMG buff only activates on every third Electrification consumption, which costs a net 210 SP, so it is best treated as a bonus rather than a core feature.
This early game setup uses Thermite Cutter and the Mordvolt Insulation gear set to boost Arclight's support performance. The sword's teamwide attack buff combines with Mordvolt's large Intellect bonus to amplify Wildland Trekker's Electric damage share for the whole team. The set also grants Arts DMG +20% while HP remains above 80%, adding a little personal damage. This build is very accessible since Thermite Cutter can be obtained from the New Horizons weapon selector early in the game. It is a reliable starting point before upgrading to the Frontiers support build.
Insights
Core Mechanics
- SP Engine: Peal of Thunder triggers on Electrification or when Electrification is consumed, restoring SP on a 3-second cooldown.
- Electrification Loop: Tempestuous Arc consumes Electrification for extra Electric damage and SP recovery; after three triggers, Wildland Trekker gives the team Electric DMG scaling with Intellect.
- Ultimate Recycle: Exploding Blitz applies Electric Infliction, then consumes it to force Electrification, allowing Arclight to retrigger her Combo Skill.
- Team Dependency: Arclight needs another source of Electric Infliction to maintain her SP generation, since her only built-in Electrification comes from her Ultimate.
Scaling
- Intellect Scaling: Wildland Trekker's team Electric DMG buff scales with Arclight's Intellect, making Intellect her most valuable stat.
- Potential Growth: Potential 3 increases Wildland Trekker's buff to 1.3x, while Potential 5 reduces the trigger requirement from 3 to 2 Electrification consumptions.
- Early vs Late: In early game, Mordvolt Insulation's flat Intellect is strong; in late game, Frontiers + Thermite Cutter provides more team utility.
- Skill Priority: Level Combo Skill first for SP recovery, then Battle Skill, and leave Basic Attack unleveled because her damage is mostly off-field.
Team Role
Arclight is a Vanguard support whose main role is to generate SP for the squad. She loops her 3-second Combo Skill by triggering Electrification, then uses Tempestuous Arc to consume it for extra SP and damage. Since her only personal Electrification source is her Ultimate, she must be paired with at least one character who can apply Electric Infliction reliably. She works best in Electric-heavy teams where Wildland Trekker's teamwide Electric damage buff can be fully utilized. A strong example is Zhuang Fangyi, who can either use the Electric Infliction from Arclight's Ultimate to trigger her own Combo Skill or use the Electrification to summon more Sunderblades. In combat, use Combo Skill before Battle Skill, then use Ultimate to refresh Electrification and repeat. Position her as an off-field enabler rather than the main damage dealer, and prioritize Intellect and Ultimate Gain to maximize her buffs and Ultimate uptime.

Explanation
Thermite Cutter is recommended from the start because it can be picked from the New Horizons selector and offers a useful teamwide attack buff.
Mordvolt Insulation provides high Intellect, which directly improves Wildland Trekker's Electric damage buff.
The HP condition is easy to satisfy if Arclight stays off-field and avoids heavy damage, giving extra Arts damage during her attacks.
Notes
- Mordvolt Insulation gives a flat Intellect boost that makes Wildland Trekker's team buff stronger in the early game.
- Thermite Cutter is still the best sword due to its teamwide attack buff, and it is handed out through the New Horizons weapon selector.
- Mordvolt Insulation also grants Arts DMG +20% when HP is above 80%, which helps her Electric damage output.
