The Endministrator is the protagonist of Arknights: Endfield and the first Operator every player controls, which makes building them well one of the most valuable early investments you can make. As a free six-star Physical Sword Guard, the Endministrator functions as a damage dealer and support hybrid that revolves around applying Originium Crystals, converting them into Crush damage, and consuming Vulnerability stacks for burst. This guide covers their best weapons, gear sets, stat priorities, skills, and team compositions so you can turn your starter character into a unit that stays relevant from the opening chapter through the current endgame.

Endministrator Overview

The Endministrator is a six-star Physical Sword Guard affiliated with Endfield Industries. As the game’s main character, you receive them at the very start during the prologue and can choose between a male and female version, switchable roughly once every twenty-four hours. Crucially, they cannot be pulled from the gacha, so they cost nothing and are available to every account regardless of luck.

What sets the Endministrator apart is their unique status-infliction kit. While they deal Physical damage and their abilities scale with Arts Intensity, they revolve around applying physical conditions like Originium Crystals, Solidification, and Crush rather than dealing direct Arts elemental damage, a combination no other launch Operator shares. They apply Originium Crystals with their Combo Skill, then shatter them for bonus Physical damage, while also consuming Vulnerability stacks set up by teammates to fuel Crush damage. This dual identity as both Vulnerability generator and consumer is why they slot into almost any Physical team, and their Combo Skill triggers whenever any ally uses a Combo Skill, giving them a universal trigger.

Stat Priorities

It helps to know which stats the Endministrator scales with, since every piece of equipment should reinforce them. Their main attribute is Agility and their secondary is Strength, forming the backbone of every build. Beyond those, they benefit from Physical Damage, Attack percentage, and Arts Intensity, the last especially relevant because it increases Crush damage. When comparing gear substats, rank them roughly as follows:

• Agility is the highest priority as the main attribute, since it drives the bulk of the Endministrator’s scaling.
• Strength comes next as the secondary attribute and should be present on every gear piece where possible.
• Physical Damage, Attack percentage, and Arts Intensity round out the build, with Arts Intensity carrying extra value for boosting Crush.

Best Weapons

Weapon choice for the Endministrator centres on reinforcing Agility and Physical damage while ideally rewarding the crystal and Physical-status interactions that define their kit. The signature weapon is the clear best option, but there are strong accessible alternatives so that free-to-play players are not left behind. The table below summarises the main choices, with fuller explanations following.

Grand Vision is the Endministrator’s signature weapon and the top choice for most players. It provides a large Agility increase alongside an Attack boost, and its passive grants a flat Arts Intensity bonus plus a substantial Physical damage increase to the next Battle Skill or Ultimate cast after the wielder applies Originium Crystals or Solidification within a short window. Because the Endministrator is one of the few Operators who can apply Originium Crystals through their own Combo Skill, they can reliably keep this bonus active, making the weapon exceptionally well suited to their rotation.

If you do not have the signature, Sundering Steel is the standout five-star alternative. It offers a flat Attack boost that increases further whenever the wielder applies a Physical status, stacking up to twice, and the Endministrator can maintain full stacks with near total uptime thanks to how often they apply Physical statuses. This makes it a strong and dependable source of raw Attack power. For very early progression, the four-star Prominent Edge grants Attack after a Battle Skill hit, but it should be treated purely as a leveling weapon and swapped out for a five-star option as soon as one becomes available.

Whichever weapon you choose, you can strengthen it through Essences, a repeatedly farmable system that raises the weapon’s stats and enhances its passive. Compatible Essences differ per weapon, with materials farmed in areas such as the Originium Science Park and Power Plateau. Essences are upgraded through Engraving, a Sanity-heavy long-term investment, so it is reasonable to prepare them for a signature weapon even before you own it.

Best Gear Sets

Gear sets provide both the attributes the Endministrator needs and powerful set effects that amplify their burst. The endgame best-in-slot is the Swordmancer set, run as a 3-piece set.” (In Arknights: Endfield, gear set bonuses trigger at 3 pieces across your 4 equipment slots, allowing 1 flex slot such as dedicated gloves. Its set effect improves Stagger efficiency and, after the wearer applies a Physical status, adds an extra hit dealing a large chunk of Physical damage along with Stagger on a short cooldown. Because the Endministrator prefers to hit once but hit very hard, this on-demand damage instance suits their playstyle perfectly, and the set naturally supplies Agility and Strength alongside Physical Damage and Ultimate Damage on its pieces.

The main alternative is the Bonekrusha set, which grants a solid Attack bonus and, whenever the wearer casts a Combo Skill, provides a stacking buff that increases the damage of their next Battle Skill by a meaningful amount, up to two stacks. Since the Bonekrusha set has no gloves of its own, a common approach is to double up on its available pieces and fill the remaining slot with a Swordmancer glove for an Ultimate Damage bonus, or with other options that offer Battle Skill efficiency or Arts Intensity depending on your needs.

Reaching either of those sets takes time, so there are sensible leveling options in the meantime. Early on, the AIC Heavy set offers Strength and a little Agility, plus healing whenever you defeat an enemy, which is genuinely useful before your survivability tools come online. Once your factory is more developed, the Armored MSGR set carries you through the first chapter with a good match to the Endministrator’s attributes and a helpful Attack boost. There is no blue-rarity set that perfectly fits their stats, so these purple options are the practical stepping stones toward the endgame builds.

Skill Priority

The Endministrator has four upgradeable skills, and knowing which to level first saves materials while maximising damage. The Endministrator has four core skills to upgrade:

• Bombardment Sequence (Ultimate) & Sealing Sequence (Combo Skill): Highest Priority. These drive your main burst loop and Originium Crystal application.
• Destructive Sequence (Basic Attack): Medium Priority. High value if the Endministrator is your actively controlled character on field.
• Constructive Sequence (Battle Skill): Lowest Priority. Mainly used for triggering Crush or utility.

The reasoning follows the kit’s damage flow. The Sealing Sequence boosts Crystal Shatter damage and extends the duration of the seal, the Bombardment Sequence provides a powerful damage multiplier with an added bonus damage modifier, and the Destructive Sequence amplifies the basic attack sequence while improving finisher and dive attack multipliers. Because so much of the Endministrator’s output comes from building and shattering Originium Crystals, the skills tied to that loop deserve your materials before the utility-focused Battle Skill.

Potentials And How To Improve Them

Unlike other Operators, whose Potentials require pulling duplicate copies from the gacha, the Endministrator’s Potentials are unlocked using a material called the Endministrator’s Token, which is earned by progressing through the Main Missions. This means their Potentials are effectively free and gated only by story progress, so it is worth advancing the campaign to collect them. Increasing Potential enhances base stats along with the Combo Skill, Ultimate, and various talents, giving a steady boost to combat performance as you play.

These upgrades are helpful rather than mandatory. The Endministrator performs well at base Potential, and the game is designed so duplicates are never required for viability, so there is no need to rush them. Because the Tokens come from natural story play rather than premium currency, most players accumulate them simply by progressing.

Best Team Compositions

The Endministrator is most at home in Physical teams, which revolve around the Vulnerability stacks they either generate or consume. Their best supporting cast are Operators who apply Vulnerability so the Endministrator can spend it on Crush for large bursts. A key point is that the Endministrator’s Battle Skill triggers Crush. Crush applies 1 stack of Vulnerability if the target currently has zero stacks. If the target already has Vulnerability stacks applied by teammates, Crush consumes all stacks instantly to deal massive burst damage, so pairing them with dedicated Vulnerability applicators is far more efficient than relying on themselves.

A strong option many players can assemble is a Cryo-Physical hybrid built around Shatter and Crush. In this setup, Alesh interacts with Originium Crystals to recover skill points and consumes Cryo Inflictions to force Solidification on enemies, which in turn triggers Estella’s Combo Skill to apply Physical Susceptibility and Vulnerability, feeding the Endministrator’s damage. Chen Qianyu, a free Operator you receive early, adds further Vulnerability stacks, and using Estella’s Ultimate after applying Physical Susceptibility generates even more. This composition leans on characters that are relatively accessible, making it a realistic goal rather than a whale-only dream team.

If you would rather not invest in the Cryo-Physical route, a straightforward free-to-play Physical team also works well, particularly if you lack premium Vulnerability enablers such as Pogranichnik or Lifeng. Chen Qianyu again serves as your Vulnerability source in this version. One pairing to avoid is running the Endministrator alongside Da Pan, since both units want to open the rotation and only the Endministrator can apply Vulnerability first through their Battle Skill, which creates a conflict rather than a synergy.

How To Play The Endministrator

In combat, the Endministrator follows a short, satisfying burst loop that lines up neatly with breaking an enemy’s Stagger bar. Whenever possible, have your supports apply Vulnerability stacks to an enemy before you commit your rotation, since consuming a larger pool of stacks dramatically increases your damage output. A clean basic rotation runs as follows:

• Let your supports apply Vulnerability stacks to the target to set up your burst.
• Use normal attacks to build, then cast the Combo Skill to apply Originium Crystals.
• Follow with the Ultimate to shatter the crystals and consume Vulnerability for a large damage spike.
• If the Ultimate is unavailable, use the Battle Skill instead to apply Crush and maintain your damage.

The key timing point is to fire the Ultimate immediately after the Combo Skill when it is available, since the freshly applied crystals are then consumed for significant additional damage. Because the Endministrator is easy to pilot and does not demand duplicates or a signature weapon, they remain one of the most reliable, beginner-friendly damage dealers in the game, whether you run them as your main carry or as a supportive damage source in a deeper Physical team.

The Endministrator is proof that a free starter Operator can stay competitive deep into a game’s lifespan when built thoughtfully. Prioritise Agility and Strength, aim for Grand Vision or Sundering Steel, work toward the Swordmancer set while using accessible purple sets in the meantime, and surround them with Operators who apply Vulnerability for their Crush to consume. Level the crystal-focused skills first, collect their Potentials through the story, and lean into the short burst loop that syncs with Stagger windows. Do that, and your first Operator will keep pulling their weight from the prologue to the endgame. For the best gaming experience, play Arknights: Endfield on BlueStacks!
