Build Notes

Arclight — endgame sub dps

Rank #2

This build turns Arclight into a sub-DPS buffer who amplifies team damage while maintaining steady SP generation. Equipping Thermite Cutter and the Frontiers set allows her to apply continuous ATK and DMG buffs, reduce her Combo Skill cooldown, and support Electric-centric teams effectively.

Thermite Cutter provides a team-wide ATK buff whenever she recovers SP, which perfectly aligns with her SP generation role. It is easily obtainable from the weapon selector in the New Horizons banner.

Frontiers gear set further decreases her Combo Skill cooldown and gives another team DMG buff when she generates SP, doubling down on her support value.

Type 50 Yinglung Gloves are used as an off-piece to maximize Combo Skill damage and boost Agility/Intellect.

Alternatives like OBJ Edge of Lightness or Twelve Questions are viable if Thermite Cutter is unavailable, though they offer slightly lower team utility.

Focuses on increasing Arclight's personal damage while providing team-wide buffs through weapon and gear effects.
Prioritize Agility and Intellect to boost her scaling and the Wildland Trekker talent's Electric DMG buff.
The Frontiers set reduces Combo Skill cooldown and grants a team DMG buff upon SP recovery.

Akekuri — endgame support

Rank #2

This endgame build maximizes Akekuri's support capabilities. Thermite Cutter and the Frontiers set provide a powerful team-wide ATK buff through SP recovery, while the Combo Skill cooldown reduction keeps her battery potential high. Eternal Xiranite Gloves T1 and the Flow essence further accelerate Ultimate and secondary stat gains. The result is a highly consistent SP generator that also amplifies team damage output.

Thermite Cutter is chosen for its powerful team ATK buff triggered by SP recovery, which synergizes with Akekuri's frequent SP generation.

The Frontiers set directly boosts her core mechanic: it shortens Combo Skill cooldown and gives the team a damage boost after she restores SP, maximizing her battery and buffer potential.

Eternal Xiranite Gloves T1 are used off-set to accelerate Ultimate charging, enabling more frequent use of her SP-restoring Ultimate.

OBJ Edge of Lightness is an alternative when paired with Heat or Electric DPS, as it boosts those elements' DMG after SP recovery, while Fortmaker improves Ultimate uptime with Intellect and Ultimate Gain Efficiency.

The Frontiers set reduces Combo Skill CD and grants a team DMG buff after SP recovery, perfectly complementing Akekuri's kit.
Thermite Cutter provides ATK% and a team-wide ATK buff when she restores SP, enhancing her support role.
Off-piece Eternal Xiranite Gloves T1 increase Ultimate Gain Efficiency, helping her charge Ultimate faster for more SP generation.

Akekuri — early game support

Rank #2

This early game setup focuses on fastest possible energy cycling. The Catastrophe set’s starting SP and Ultimate Gain Efficiency let Akekuri unleash her SP-restoring Ultimate quickly. Combined with Thermite Cutter’s ATK buff, it establishes a solid foundation for team SP management from the start of a fight.

The Catastrophe set is ideal for early game because it helps Akekuri access her Ultimate faster and provides a starting SP spike, jump-starting the team’s energy economy.

Thermite Cutter provides a consistent team ATK buff that benefits the whole squad early on.

Off-pieces are chosen for Intellect and Will, which enhance her SP recovery and provide supplementary stats.

The Catastrophe set increases Ultimate Gain Efficiency and grants an initial 50 SP at combat start, allowing early Ultimate casts.
Thermite Cutter remains the best weapon even early on for its team ATK buff.
Miner Fists T1 gloves and Catastrophe Filters prioritize Intellect and Will to boost SP generation and stats.
