A

endgame support

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 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.

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

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.

Notes

  • 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.
