The best Akekuri build in Arknights: Endfield (Version 1.5) is Thermite Cutter with Frontiers. Updated September 20, 2026
The best Akekuri build in Arknights: Endfield (Version 1.5) is Thermite Cutter with Frontiers. 4-star Heat Vanguard operator.
Frontiers is Akekuri's best set in almost every case, its three-piece bonus keeping a team-wide DMG% buff up nearly permanently while also cutting her Combo Skill's cooldown.
3PC3-piece set effect: Wearer's Arts Intensity +30. After the wearer applies Combustion, the wearer gains Heat DMG +50% for 10s. After the wearer applies Corrosion, the wearer gains Nature DMG +50% for 10s. The aforementioned effects cannot stack.
No Set: Building Akekuri with no set at all and maximum Ultimate Gain Efficiency instead regenerates more team SP and keeps her ATK% and Link buffs up, and pieces with Intellect boost the SP her Combo Skill recovers.

Arcane self-sustains her own Corrosion, so this team spends its other three slots on Amp and healing rather than on a second Nature source. Tangtang lays the Cryo her infliction consumes, and Xaihi’s buffs do more for the total damage than a fourth attacker would.

Akekuri, this operatorVanguard · SPRossi’s Ultimate alone kills most enemies, so this build stacks Arts Reactions ahead of it rather than leaning on her Physical side. Perlica’s Electric and Tangtang’s Cryo both feed the burst, and the fourth slot is whichever buffer gets the most out of the one cast that matters.

Xaihi’s Amp is high enough that Prydwen credits much of this team’s damage to her buffs rather than to Last Rite’s own numbers.
