Here’s a complete Endministrator (Endmin) best build guide for Arknights: Endfield (updated as of late March 2026). The Endministrator is the game’s main character—a free 6★ Physical Sword Guard who serves as a strong DPS / Vulnerability consumer. He excels at applying Originium Crystals (via Combo Skill), converting them into Crush (a physical status that deals bonus damage), and delivering burst damage through his ultimate and skills. His kit includes crowd control, team ATK buffs (via potentials), and strong single-target focus with some AoE potential in stagger windows.
Administrator Overview & Playstyle
- Class/Element: 6★ Guard / Physical (Sword user)
- Main Attribute: Agility (gives ~1% ATK per point)
- Secondary Attribute: Strength (~0.4% ATK per point)
- Key Mechanics: Applies Originium Crystals → Detonates them for crush damage. Consumes vulnerability stacks (set up by teammates) for extra bursts. Talents like Essence Disintegration provide ATK buffs on crystal application.
Playstyle: Frontline DPS with short burst loops. Use normal attacks to build, combo/battle skills to apply crystals and consume vulnerability, and then the ultimate for big damage. He shines in physical teams where allies apply vulnerability for him to exploit.
Endmin’s Best Weapons & Essence Priority
Endministrator wants weapons that boost Agility, Physical DMG, or Arts Intensity (boosts Crush) or provide buffs on Crystal/Vulnerability interactions.
Best-in-Slot:
- Grand Vision (6★ Signature) — Top choice for most players. Boosts Agility + Arts Intensity. Passive triggers massive physical DMG buffs when applying Originium Crystals (perfect synergy with his Combo Skill). Often called “broken” in community math due to high uptime and multipliers.
Strong Alternatives:
- Eminent Repute (6★)—Excellent in vulnerability-heavy teams. Applies ATK buffs on vulnerability consumption and shares half the buff with the team. Some calcs show it edging out Grand Vision in coordinated team damage.
- Rapid Ascent (6★) — Good Crit Rate + Physical DMG; boosts Battle Skill/Ultimate damage.
- Sundering Steel (5★) — Best F2P/early-game option. High Agility + Physical DMG; passive stacks on Physical status application. Easy to max and very competitive at high investment.
Essence Priority (slot into weapon for final stat boosts):
Prioritize essences with Agility (main) → Strength or Physical DMG / Arts Intensity / Combo Skill DMG. Look for triple-stat essences matching the weapon’s passive (e.g., “Detonate” or crystal-related for Grand Vision). Early game, any Agility/Strength essence works. Max essence levels for the last weapon stat boosts.
Endymin’s Best Gear Set
Focus on Agility’s main stats with substats in Strength, Physical DMG, Combo Skill DMG, Arts Intensity, and Crit where possible. Avoid sets that rely on you applying vulnerability (Endmin mostly consumes it).
Recommended Endgame Sets:
- Swordmancer (Primary BIS) — Boosts Agility/Strength + Physical DMG and stagger efficiency. Pairs excellently with his kit for sustained and burst damage. Typical pieces: Swordmancer heavy armor, TAC gauntlets, and flint (kits).
- Bonekrusha (strong for stagger/bosses) — Excellent damage vs. staggered enemies; good mix with Swordmancer (e.g., Bonekrusha Mask + Heavy Armor for stagger bonus). Community tests show it to be competitive with or better than full Aethertech in staggered scenarios.
Early/Mid-Game:
- Roving MSGR (Blue/Purple) — Boosts Agility + Physical DMG at high HP. Easy to farm and solid transition set.
Notes on Aethertech: Mixed opinions—some older guides recommend it for Vulnerability synergy, but recent math shows it underperforms on Endmin because he doesn’t reliably apply the stacks himself (he consumes them). Use only if running specific off-piece mixes (e.g., Aethertech Gloves for Arts Intensity).
Stat Priority: Agility (main) > Strength > Physical DMG % / Combo DMG % > Arts Intensity > Crit Rate / DMG.
Endmin’s Best Teams
Endministrator thrives in physical teams that apply vulnerability (for him to consume) and enable stagger/breach for big burst windows. Teams revolve around 4-operator combos with skill chaining.
Premium Physical Burst Team:
- Endministrator (Main DPS / Crystal detonator)
- Chen Qianyu (Vulnerability applicator + sub-DPS)
- Lifeng (More Vulnerability via Knock Down + combo support)
- Pogranichnik (Breach / SP gen / Vanguard support)
This is the most common high-end comp for massive nuke rotations when all Ults are up and the enemy is staggered.
F2P-Friendly / Early Teams:
- Endministrator + Chen Qianyu + Pogranichnik + Akekuri (or Perlica/Ardelia for healing)
- Endministrator + Chen Qianyu + Ardelia (heals + support) + Pogranichnik
Sample Rotations (simplified; adjust for energy):
- Basic Rotation: Supports applying Vulnerability → Endmin Combo (Crystals) → Consume/Detonate → Ultimate on staggered target.
- Nuke Rotation (with all Ults + stagger): Pog Ult → Lifeng/Chen Skills → Endmin Combo → Endmin Ult → Lifeng/Chen Ults → Repeat consumption.
He also works in freeze/control variants with operators like Estella, but physical burst is his strongest archetype.
Endomin Potentials
As the main character, many potentials are unlocked via story progression/trust (free, no dupes needed). Currently known:
- Potential I: Improves Constructive Sequence (Combo Skill) — better SP return or efficiency when consuming Originium Crystals.
- Potential II: Essence Disintegration upgrade—when Endmin gains his ATK buff, allies gain half of it (great team-wide value).
Higher potentials (III–V) provide further improvements to talents, damage, or utility (exact values depend on your progress; check in-game). Investing in him is low-risk since he’s free and central to many teams.
Additional Tips
- Skill Priority: Ultimate > Combo/Battle Skill > Basic Attack. Max skills to 9+ for endgame.
- Progression: Farm agility gear early. Upgrade Grand Vision or Sundering Steel first. Use him as your carry while building supports like Chen and Pog.
- Strengths: Easy to play, strong burst, team buffs via potentials, good in story/endgame physical content.
- Weaknesses: Relies on teammates for vulnerability setup; single-target focused without stagger.
The Administrator is a reliable, high-value unit—especially as a free 6★ DPS who scales well into late game. Pair him with strong physical supports for the best results.
