Alesh

early game hybrid

supportsp_generatorcryovanguard

Alesh ranks in A tier because his SP generation is excellent but heavily conditional. He needs enemies with Cryo Infliction stacks and a team built around frequent Arts Reactions to shine. His kit also relies on a chance-based Rare Fin mechanic, which can make his performance inconsistent in tough fights.

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.

Insights

Core Mechanics

Alesh's Ultimate applies Cryo Infliction in an area and recovers SP per enemy defeated, making wave clear a direct fuel source for the team.
His Battle Skill consumes all Cryo Infliction stacks on one target, forcibly applies Solidification, and returns SP based on stacks consumed—single-target only.
The Combo Skill Auger Angling unlocks after an Arts Reaction or Originium Crystal consumption, with a chance to hook a Rare Fin for bonus damage and extra SP.
His talent Veteran Angler scales Rare Fin chance with Intellect, reaching full effect at around 600 Intellect, while Flash-frozen for Freshness refunds Ultimate Energy when Solidification or Originium Crystals appear.

Scaling

Intellect is the crucial secondary attribute, directly raising both Rare Fin chance and the damage bonus from his Combo Skill; pushing it to 600 is the top priority for late-game value.
Early on Alesh can contribute with modest investment through the Mordvolt Insulation set, but he truly transforms once the Frontiers set and high-Intellect gear come online.
His team-wide utility scales with teammate composition—Cryo appliers and characters who consume Originium Crystals increase his SP output and Ultimate uptime significantly.

Team Role

Alesh is best used as the team's dedicated SP battery and Cryo enabler rather than the on-field damage dealer. He works best when placed alongside units that can apply Cryo Infliction frequently, allowing his Battle Skill to consume stacks and generate SP. His Combo Skill also triggers off Arts Reactions, so pairing him with reaction-hungry DPS characters creates a smooth loop: reactions fuel his Combo, his combo feeds SP, and the team spends that SP on heavy abilities. His forced Solidification effect opens extra synergy with Physical or reaction-focused teammates, and he can even consume Originium Crystals from allies like Endministrator to accelerate his own rotation.

Explanation

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.

Notes

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.
