Arclight

endgame sub dps

sub_dps support

Arclight provides solid SP regeneration for the team via her frequent Combo Skill, but she depends on Electrification to trigger it. Since her kit only applies Electrification through her Ultimate, she needs at least one other Electric source in the party. Her Electric DMG buff only activates every third Electrification consumption, which uses SP over time and feels inconsistent for a support role.

This build transforms Arclight into a team-oriented sub-DPS. The Frontiers set and Thermite Cutter work together to grant consistent damage buffs to the whole party whenever she uses her Combo Skill. The off-piece gloves further boost her personal Combo Skill output, making her a valuable hybrid support that also contributes meaningful damage.

Insights

Core Mechanics

Her Combo Skill recovers SP and has a short 3-second cooldown, triggering whenever an enemy suffers or consumes Electrification.
The Battle Skill consumes Electrification for bonus Electric DMG and extra SP, but only every third use grants the team an Electric DMG buff based on her Intellect.
Her Ultimate applies Electric Infliction and can force Electrification on enemies already affected, enabling a follow-up Combo Skill without external help.

Scaling

Arclight's utility scales with her Intellect for the team Electric DMG buff, while her personal damage scales with Agility and ATK.
Early game she acts as a pure SP battery; late game with the Frontiers set and Thermite Cutter she becomes a team buffer and sub-DPS.

Team Role

Arclight fits best as a SP generator and sub-DPS in teams with another Electric character who can reliably apply Electrification. She excels in fast-paced rotations where her low-cooldown Combo Skill keeps the team's energy high. Her weapon and gear can shift her from pure support to a hybrid buffer/damage dealer, but she always needs a teammate to supply the Electric Infliction she cannot easily produce herself.

Explanation

Thermite Cutter is chosen because its Flow essence gives a teamwide ATK buff that stacks twice, perfect for her SP-recovery playstyle.

Frontiers set amplifies her SP generation with cooldown reduction and turns every SP recovery into a team damage buff.

The off-piece gloves maximize her Combo Skill damage, which is her main source of SP and damage.

Alternative weapons like OBJ Edge of Lightness offer similar team buffs but are more restrictive (only Heat/Electric) and less accessible.

Notes

Frontiers set reduces Combo Skill cooldown by 15% and grants the team +16% damage for 15s whenever Arclight recovers SP.
Type 50 Yinglung Gloves are an off-piece that boost Combo Skill damage and provide Agility/Intellect, enhancing both her damage and buff scaling.
