Alesh Best Build Guide 2026

Alesh is a 5-star Cryo Sword Vanguard in Arknights: Endfield. Alesh is not a pure DPS. Alesh is better understood as a Cryo support and SP generator built around Cryo Infliction, Solidification, Arts Reactions, and team rotation support. Game8 lists Alesh as a Cryo Sword Vanguard with Strength as the main attribute and Intellect as the secondary attribute.

Alesh’s value comes from:

• applying Cryo Infliction

• forcing Solidification

• recovering SP

• enabling reaction-based combos

• supporting Physical and Cryo team rotations

Core takeaway:

Alesh is a tempo support, not a carry.

Alesh Overview

Alesh is best used as a teammate, not as the controlled operator. Game8 specifically notes that Alesh is mainly played as the team’s SP generator and a unit that force-applies Solidification to enemies.

Alesh’s core identity:

• Cryo support

• SP battery

• Solidification enabler

• reaction-based teammate

This means Alesh works best when the team can already apply Cryo Infliction or trigger Arts Reactions frequently.

Strengths and Weaknesses

Strengths

• strong SP generation

• good Cryo Infliction utility

• enables Solidification

• works well in reaction-based teams

• can support Physical damage setups

Weaknesses

• not a strong standalone DPS

• depends on team synergy

• some value depends on enemy count and reaction setup

• less consistent than top-tier universal supports

Game8 rates Alesh as B-tier and explains that Alesh has strong SP generation but several restrictions, needing teams with high Cryo Infliction and enough weak enemies to fully maximize utility.

Key takeaway:

Alesh is valuable in the right shell, but not universal.

Skill Breakdown

Basic Attack – Basic Rod Casting

Alesh’s Basic Attack is a 5-sequence Physical attack.

Core points:

• deals Physical DMG

• Final Strike deals Stagger when Alesh is controlled

• Finisher Attack deals heavy Physical DMG

• Finisher Attack also recovers some SP

Basic Attack is not Alesh’s main value. It is mostly filler unless you are using Finisher interactions.

Key takeaway:

Basic Attack is low priority compared with Alesh’s Ultimate, Battle Skill, and Combo Skill.

Ultimate

Alesh’s Ultimate is the first skill priority.

Why it matters:

• applies Cryo Infliction

• deals AoE damage

• recovers SP

• gains more SP when enemies are defeated

Game8 states that Alesh’s Ultimate is the strongest ability because it applies Cryo Infliction, deals decent damage, and generates SP, with SP generation increasing based on enemies defeated.

Key takeaway:

Ultimate is Alesh’s most important skill because it starts the Cryo and SP engine.

Battle Skill

Alesh’s Battle Skill is the second priority.

Core function:

• deals Physical DMG

• consumes Cryo Infliction stacks

• recovers SP

• forces Solidification

Game8 explains that Alesh’s Battle Skill consumes Cryo Infliction stacks from the enemy, recovers more SP when more stacks are consumed, and forces Solidification, which enables strong combos with Physical or Arts reactions.

Key takeaway:

Battle Skill turns Cryo status into SP and Solidification value.

Combo Skill

Alesh’s Combo Skill is the third priority.

Core function:

• becomes available after an Arts Reaction

• also works when an Endministrator Originium Crystal is consumed

• deals Physical DMG

• recovers SP

• can trigger Rare Fin for stronger damage and SP recovery

Game8 notes that Alesh’s Combo Skill activates after an Arts Reaction or Endministrator crystal consumption, and that Rare Fin can increase damage and SP gained.

Key takeaway:

Combo Skill adds SP and reaction value, but is less consistent than Ultimate and Battle Skill.

Skill Priority

Recommended upgrade priority:

1. Ultimate

2. Battle Skill

3. Combo Skill

4. Basic Attack

Game8 gives this exact priority and explains that Ultimate is strongest, Battle Skill enables SP and team combos, Combo Skill is useful but less consistent, and Basic Attack is the lowest priority.

Talent Priority

Recommended talent priority:

1. Flash-frozen for Freshness

2. Veteran Angler

Game8 recommends Flash-frozen for Freshness first because it helps Alesh cast Ultimate more often. Veteran Angler improves Rare Fin trigger efficiency based on Intellect, with around 150 Intellect needed to maximize its effect.

How Alesh Actually Works

Alesh should be played as a reaction-based SP engine.

Real gameplay loop:

1. Apply Cryo Infliction

2. Use Ultimate to spread Cryo and recover SP

3. Use Battle Skill to consume Cryo Infliction

4. Force Solidification

5. Trigger Combo Skill after Arts Reaction

6. Repeat

Game8’s recommended play pattern is clear: apply Cryo Infliction with Ultimate, force Solidification and gain SP with Battle Skill, then use Combo Skill after an Arts Reaction.

Core insight:

Alesh does not win by raw damage. Alesh wins by making the team rotate faster.

Best Weapons for Alesh

Best Weapon – Finchaser 3.0

Finchaser 3.0 is the best weapon for Alesh.

Key effects:

• ATK +14.0%

• when Battle Skill applies Solidification, the target suffers Cryo DMG Taken +19.6% for 15s

• Cryo DMG Dealt +34.7%

• Strength +124

Game8 ranks Finchaser 3.0 as Alesh’s best weapon and states that it improves Cryo DMG and Strength, while also helping team Cryo damage through the Cryo DMG Taken effect.

Key takeaway:

Finchaser 3.0 is best because it directly supports Alesh’s Cryo and Solidification role.

Alternative Weapon – Thermite Cutter

Thermite Cutter is a strong team-support alternative.

Key effects:

• ATK +28.0%

• after the wielder’s skill recovers SP or grants Link state, the entire team gains ATK +14.0% for 20s

• team ATK buff can stack up to 2 times for same-name effects

Game8 notes that Thermite Cutter is a good alternative because Alesh’s role is mainly team support, and the weapon’s team ATK buff can be valuable in some situations.

Key takeaway:

Thermite Cutter is better when you want more team buff value.

Early Game Weapon – Fortmaker

Fortmaker is the recommended early-game option.

Key effects:

• ATK +14.0%

• Arts Intensity +70

• Ultimate Gain Efficiency +37.1%

• Intellect +124

Game8 recommends Fortmaker early because it fits Alesh’s kit and stat requirements, especially by improving Ultimate availability.

Key takeaway:

Fortmaker is a good early weapon because Alesh wants more Ultimate uptime.

Best Gear for Alesh

Best Set – Frontiers

Frontiers is Alesh’s best gear set.

Why it works:

• supports Alesh’s SP regen-centric playstyle

• gives a team damage buff when Alesh recovers SP

• improves Combo Skill cooldown

• increases Alesh’s ability to generate more SP over time

Game8 states that Frontiers is Alesh’s best gear set because it gives extra team damage when Alesh recovers SP and lets Alesh cast Combo Skill more frequently.

Recommended late-game gear direction:

• Frontiers Armor

• Eternal Xiranite Gloves as an offset piece

• Frontiers Comm T1 kits

Game8 recommends Frontiers Armor for Ultimate DMG, two Frontiers Comm T1 kits for Cryo DMG Bonus, and Eternal Xiranite Gloves for Ultimate Gain Efficiency.

Key takeaway:

Frontiers is best because Alesh recovers SP often and can turn that into team damage.

Early Game Gear

Recommended early setup:

• Mordvolt Insulation Vest

• Armored MSGR Gloves

• Armored MSGR kits

Game8 recommends Armored MSGR in early game because it provides Strength, while Mordvolt Insulation Vest is useful as an off-piece because it gives both Strength and Intellect.

Key takeaway:

Early game Alesh should prioritize Strength, Intellect, and survivability.

Stat Priority

Best stat direction:

1. Strength

2. Intellect

3. Ultimate Gain Efficiency

4. Cryo DMG

5. Skill efficiency

Reason:

• Strength supports Alesh’s main attribute

• Intellect improves certain utility interactions

• Ultimate Gain helps Alesh cast Ultimate more often

• Cryo DMG supports Alesh’s reaction role

Best Teams for Alesh

Best Pairings

Alesh works especially well with:

• Estella

• Yvonne

• Snowshine

• Endministrator

Estella pairs well with Alesh because Alesh’s skill applies Solidification, which immediately enables Estella to trigger Combo Skills and shatter the effect for additional damage.

Cryo Solidification Team

Yvonne + Estella + Alesh + Xaihi

Why it works:

• Yvonne provides Cryo synergy

• Estella benefits from Solidification

• Alesh enables SP and reaction flow

• Xaihi fills team utility

Hybrid Electric Burst Team

Perlica + Arclight + Alesh + Zhuang Fangyi

Why it works:

• Perlica provides stable Electric Infliction and Electrification setup

• Arclight improves SP flow and speeds up the Electric rotation

• Alesh adds extra SP recovery and reaction support

• Zhuang Fangyi acts as the main burst DPS and benefits from smoother team cycling

Key takeaway:

This team is not a pure Cryo team. It is a hybrid support shell where Alesh helps improve SP flow while Zhuang Fangyi converts the setup into burst damage.

Advanced Tips

Use Ultimate early in fights with multiple enemies.

Reason:

• applies Cryo Infliction

• recovers SP

• can gain more SP when enemies are defeated

Use Battle Skill only when Cryo Infliction is already active.

Reason:

• consumes Cryo Infliction

• forces Solidification

• gives more SP value

Use Combo Skill after Arts Reactions.

Reason:

• restores SP

• supports the team’s reaction loop

Watch for Rare Fin.

Reason:

• increases Combo Skill damage and SP gain

• becomes more valuable with Veteran Angler and Intellect investment

Is Alesh Worth Building?

Alesh is worth building if:

• you play Cryo teams

• you use Estella

• you use Endministrator

• you want more SP generation

• you enjoy reaction-based teams

Alesh is less valuable if:

• you want a pure main DPS

• your team does not apply Cryo Infliction

• you do not use Solidification or Arts Reaction setups

Final verdict:

Alesh is not a universal carry, but Alesh is a useful Cryo support and SP engine in the right team.
