Build Notes

Alesh—endgame support

Rank #2

This endgame build turns Alesh into a pure support engine. By pairing Thermite Cutter with the Frontiers set, every SP recovery action he performs chips in a team-wide Attack boost and a 16% DMG boost, while the reduced Combo Skill cooldown lets him generate even more SP. The individual gear pieces are selected to push his Intellect as close to 600 as possible, maximizing his Rare Fin proc rate and making his Combo Skill a much more reliable SP battery. The result is a support character who can dramatically improve the entire squad's damage output and ability uptime, though players should be mindful that some weapon alternatives like Finchaser 3.0 can interfere with Cryo-focused DPS teammates.

Thermite Cutter is chosen because its effect boosts the entire team's Attack whenever Alesh recovers SP, which happens constantly in his rotation.

The Frontiers set adds a 16% team DMG buff after SP recovery and shortens Combo Skill cooldown, ensuring Alesh can cycle his skills faster.

Redeemer Armor and the Frontiers Fiber Gloves provide the Intellect and Ultimate Gain Efficiency that Alesh needs to reach high Rare Fin chance and spam his Ultimate.

Two Frontiers Extra O2 Tube T1 kits are recommended for the secondary attribute bonus; the source notes this is important to push Intellect toward the 600 cap.

If you're not using Thermite Cutter, OBJ Edge of Lightness works well in Heat/Electric teams, and Fortmaker is a general-purpose fallback that improves Intellect and Ultimate gain.

This build maximizes Alesh's supportive loop: every SP recovery powers team-wide Attack and DMG bonuses.
High Intellect from the gear directly increases his Rare Fin chance, turning his Combo Skill into a more reliable SP source.
Thermite Cutter's team ATK buff complements the Frontiers set's DMG buff, making Alesh a one-man team amplifier.
Finchaser 3.0 is his signature weapon but can strip Cryo stacks needed by Cryo DPS units, so use it with caution.

Alesh—early game hybrid

Best in Slot

This early game setup focuses on getting Alesh's Intellect high enough that his Rare Fin mechanic begins to function reliably. OBJ Edge of Lightness offers solid flow and attack bonuses, and its team-wide buffs are particularly strong when Alesh is paired with Heat or Electric allies. The Mordvolt Insulation set contributes a flat +50 Intellect, which is a massive boost at low investment, plus conditional Arts DMG that makes his Cryo Ultimate hit harder. Fortmaker is listed as a flexible alternative for teams that don't rely on the elemental synergy. This build is a practical stepping stone until the Frontiers set and Thermite Cutter become available in the late game.

OBJ Edge of Lightness provides useful Essence bonuses like Flow and Attack Boost while also giving early-game stats that keep Alesh relevant.

Its team-wide buffs are most impactful when paired with Heat or Electric units, so it's the top pick for those specific team comps.

The Mordvolt Insulation gear set adds flat Intellect, directly improving Alesh's Veteran Angler talent and making his Combo Skill more rewarding.

The individual pieces also boost Strength, Attack, Cryo DMG, and Arts DMG, covering both his supportive needs and personal damage.

If Alesh is being used outside Heat/Electric teams, Fortmaker takes over as the better all-purpose weapon due to its Intellect and Ultimate gain bonuses.

OBJ Edge of Lightness is the recommended early weapon, especially when playing Alesh in a Heat or Electric composition.
Fortmaker is a solid general-purpose substitute if you plan to run Alesh in teams outside of those elemental setups.
The Mordvolt Insulation set grants a flat +50 Intellect, which is exactly what Alesh needs early to make his Rare Fin talent start working.
Keep Alesh above 80% HP to enjoy the set's 20% Arts DMG bonus, which also increases his Cryo Ultimate damage.

Arclight—endgame support

Rank #2

This endgame build turns Arclight into a dedicated support and SP battery. Thermite Cutter provides a teamwide ATK buff, while the Frontiers gear set adds another stacking team damage buff every time she recovers SP with a skill. Thanks to her 3-second cooldown Combo Skill, this happens frequently. A Redeemer Seal off-piece raises Intellect and Ultimate Gain, making her Wildland Trekker buff stronger and letting her use Exploding Blitz more often to apply Electrification. The build prioritizes Flow, Attack Boost, and Will Boost on the weapon, and Intellect/Ultimate Gain on gear. It performs best in Electric teams that can supply external Electric Infliction; without that, Arclight cannot maintain her SP generation loop.

Thermite Cutter is chosen because its teamwide attack buff stacks well with Arclight's support role and is accessible from the New Horizons weapon selector.

The Frontiers set effect triggers whenever Arclight regenerates SP, which happens constantly through her low-cooldown Combo Skill, granting the whole team +16% damage for 15 seconds.

Intellect and Ultimate Gain are prioritized so Wildland Trekker's Electric damage buff scales higher and Exploding Blitz comes up more often for extra Electrification.

If Thermite Cutter is unavailable, OBJ Edge of Lightness still provides Flow and Attack Boost but only buffs Heat and Electric damage. Fortmaker remains a last-resort option.

Thermite Cutter grants a teamwide attack buff, making it the best support weapon for Arclight.
The Frontiers set provides Combo Skill cooldown reduction and a team damage buff whenever Arclight recovers SP with a skill.
Redeemer Seal is the off-piece, supplying Intellect and Ultimate Gain to boost Wildland Trekker and Ultimate uptime.
OBJ Edge of Lightness is a decent fallback that increases Heat and Electric damage, while Fortmaker is only a stat stick.

Akekuri—endgame support

Rank #2

This endgame build transforms Akekuri into a dedicated support that constantly feeds the party SP and amplifies damage. The Frontiers set shortens her Combo Skill cooldown and rewards every SP recovery with a 16% team DMG buff, while Thermite Cutter adds an ATK buff after SP restoration. With high Intellect and Ultimate Gain, she cycles between Flash and Dash and SQUAD! ON ME! to keep the team's energy flowing, and the Redeemer Seal off-piece ensures her Ultimate comes back quickly for more Link uptime. This build is ideal for team comps that rely on expensive Ultimates and burst rotations.

Thermite Cutter is chosen because Akekuri constantly restores SP via Combo Skill and Ultimate, letting the weapon's ATK buff trigger frequently for the whole party.

Frontiers set's CD reduction lets Flash and Dash come up more often, and the DMG buff after SP restoration rewards the same actions she already performs.

Redeemer Seal is used as an off-piece to improve Ultimate Gain Efficiency, so she can use her Ultimate more often and deliver more SP and Link buffs.

If you lack Frontiers or Thermite Cutter, early Catastrophe gear and free weapons are acceptable until the endgame set is assembled.

Frontiers set gives +15% Combo Skill CD reduction and a 16% team DMG buff for 15s after SP recovery, which pairs perfectly with Akekuri's SP loop.
Thermite Cutter adds a party ATK buff after restoring SP, making Akekuri a stronger offensive support.
Use OBJ Edge of Lightness when the team is centered on Heat or Electric; Fortmaker is a fallback if you want faster Ultimates but lose team buffs.

Akekuri—early game support

Rank #2

This early game build gives Akekuri a strong foundation as a SP generator without requiring rare gear. The Catastrophe set raises Ultimate Gain Efficiency and starts battles with 50 SP, letting her fire SQUAD! ON ME! early and often. Thermite Cutter is the go-to weapon since it is free from the New Horizons Weapon Supply and grants party ATK when SP is restored. The build is budget-friendly and prepares her for the endgame Frontiers setup, while still delivering useful team support in the first stages of progression.

The early game build focuses on getting Akekuri's Ultimate online quickly, so the Catastrophe set's Ultimate Gain Efficiency and starting SP are the key choices.

Thermite Cutter remains the best weapon even at this stage because it's free and its party ATK buff works with her frequent SP recovery.

Use Miner Fists and Catastrophe Filter pieces because they are readily available early and complete the Catastrophe set bonus.

Catastrophe set increases Ultimate Gain Efficiency by 20% and starts each battle with 50 SP, helping Akekuri reach her Ultimate faster.
Thermite Cutter is free from the New Horizons Weapon Supply, making it the best affordable weapon for early support Akekuri.
This setup is a foundation; replace it with Frontiers set and Redeemer Seal as you progress.
