Arclight

early game support

vanguardsupportsp_generator

Arclight provides strong SP generation for her team through her low-cooldown Combo Skill, but she depends on Electrification to trigger it. This restricts her to teams with at least one additional Electric source, as her own Electrification comes only from her Ultimate. Her Electric DMG buff is a nice bonus but requires three Electrification consumptions, which conflicts with her SP-generating role.

A beginner-friendly build that focuses on boosting Arclight's Intellect to enhance her talent buff. The Mordvolt Insulation set is easy to obtain and provides solid stats, while the Thermite Cutter remains a strong weapon choice due to its team ATK buff. This build works well until the player can acquire the Frontiers set.

Insights

Core Mechanics

Arclight's Peal of Thunder (Combo Skill) recovers SP and deals Physical DMG whenever an enemy suffers or consumes Electrification. It has a 3-second cooldown and is the core of her utility.
Her Exploding Blitz (Ultimate) applies Electric Infliction and then converts it to Electrification, enabling her Combo Skill. The delay between infliction and Electrification can be used in team rotations.
Wildland Trekker talent grants team-wide Electric DMG based on Arclight's Intellect after triggering the additional effect of Tempestuous Arc three times.

Scaling

Arclight scales well with Intellect as it amplifies her Wildland Trekker buff. She also benefits from Ultimate Gain Efficiency to use her Ultimate more often for self-Electrification.
In early game, she provides decent support with the Mordvolt Insulation set's Intellect boost; in late game, the Frontiers set and Thermite Cutter elevate her team buffs significantly.
Her performance is highly team-dependent: she needs at least one other Electric inflictor to consistently trigger her Combo Skill and maximize SP generation.

Team Role

Arclight acts as a secondary damage dealer and primary SP battery for the team. She fits best in Electric-centric teams where her Combo Skill can be triggered regularly. Her Battle Skill consumes Electrification to recover SP and deal Electric DMG, while her Ultimate provides an on-demand Electrification source. She synergizes well with characters like Zhuang Fangyi who can utilize either Electric Infliction or Electrification for their own skills. In teams lacking other Electric sources, her SP generation becomes inconsistent.

Explanation

Thermite Cutter is again the best weapon because it offers team utility even at low levels.

Mordvolt Insulation set's flat Intellect boost directly increases Arclight's Wildland Trekker buff, making her early-game support more effective.

The set's Arts DMG bonus (when HP>80%) provides a minor damage increase for her Electric attacks.

Notes

Thermite Cutter is obtainable early from the New Horizons weapon selector.
Mordvolt Insulation provides a flat Intellect boost and conditionally increases Arts DMG.
