Build Notes

Arclight — endgame sub dps

Rank #2

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.

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.

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.

Akekuri — endgame support

Rank #2

This endgame build transforms Akekuri into a potent team buffer. By stacking SP recovery triggers, she consistently activates the Thermite Cutter's Flow buff and the Frontiers set's damage bonus. The build prioritizes Ultimate Gain Efficiency to keep her Ultimate ready, which in turn provides Link and more SP. The result is a significant boost to the entire team's offensive output without requiring Akekuri to deal damage herself.

Thermite Cutter is chosen because its Flow essence procs on any SP recovery, which Akekuri does constantly with her Combo Skill and Ultimate.

Frontiers set further amplifies her supportive role by reducing cooldown on her main SP-generation skill and providing a damage boost to the whole team.

OBJ Edge of Lightness is a good alternative if the team is focused on Heat or Electric damage, as it boosts those elements.

Fortmaker can be used if more personal Ultimate gain is needed, but its buffs are less impactful than the team-wide effects of other options.

Thermite Cutter's Flow essence increases team ATK by 14% for 20s after Akekuri recovers SP, stacking up to 2 times.
The Frontiers 4-set bonus reduces Combo Skill cooldown by 15% and grants party DMG +16% after SP recovery.
Redeemer Seal off-piece maximizes Ultimate charge rate for more frequent team buffs.
