From a value perspective, Constructive Sequence provides a solid damage multiplier along with a minor increase to Stagger, but its overall returns are noticeably lower compared to the other three options at the same level of investment.
Sealing Sequence delivers a substantial boost to Crystal Shatter damage, extends seal duration, and adds a small Stagger increase. Bombardment Sequence stands out with a powerful damage multiplier, an additional bonus damage modifier, and a Stagger enhancement, while Destructive Sequence greatly amplifies basic attack sequence damage and also improves both finisher and dive attack multipliers.

| Arknights: Endfield Endministrator Best Weapons
Grand Vision
Grand Vision is an excellent weapon choice for the Endministrator, as it provides a flat increase to Arts Intensity along with a Physical damage bonus to the next Battle Skill or Ultimate used. Activating this effect requires the application of Originium Crystals (or Solidification), and the Endministrator is among the few Operators capable of reliably triggering this condition through their Combo Skill.
Sundering Steel
Sundering Steel provides a flat increase to Attack, with additional bonuses gained each time a Physical status effect is applied. The Endministrator can maintain full stack uptime with little effort, allowing this effect to remain active almost constantly. As a result, it stands out as a highly effective choice for boosting raw Attack power.

Swordmancer
The Swordmancer set enhances Stagger efficiency and provides a one-time, massive damage bonus to the next instance of Physical damage dealt. Because the Endministrator favors heavy, high-impact strikes over frequent lighter hits, this set synergizes extremely well with their playstyle, while also offering an ideal mix of Main and Secondary attributes.
Bonekrusha
The Bonekrusha set does not include gloves, but you can compensate by equipping two Bonekrusha Masks (T1) pieces to gain a solid Critical Rate increase. For the offset slot, the Swordmancer TAC Fists are a strong choice, providing an Ultimate Damage bonus. Alternatively, MI Security gloves can be used to boost Battle Skill Efficiency, while Æthertech gloves offer an Arts Intensity increase, making them viable substitutes depending on your build focus.
| Arknights Endfield Endministrator Best Team Comps
The Endministrator can adapt to two main roles based on team needs. As a main DPS, they consume Vulnerability stacks with Crush to deal heavy burst damage. As a support DPS, they focus on applying Originium Crystals and buffing allies while another Operator handles Vulnerability consumption.
This flexibility comes from their Combo Skill, which triggers whenever any ally uses a Combo Skill, allowing the Endministrator to fit into almost any team. They shine most in Physical teams built around Vulnerability stacks. Chen Qianyu is a near-mandatory partner thanks to her free, automatic Vulnerability application, while Ardelia adds both healing and Physical Susceptibility, covering sustain and damage amplification at once.

| How to Play Endministrator
The Endministrator’s kit is built entirely around Originium Crystals generated by their Combo Skill, so understanding how this mechanic works is key to using Endmin effectively.
The Combo Skill activates whenever any allied Operator deals damage with a Combo Skill, making the trigger condition extremely easy to meet. When triggered, Endmin dashes toward the target, dealing Physical damage and encasing the enemy in Originium Crystals for up to 5 seconds. Normal enemies are fully immobilized, while elites and bosses cannot be frozen but still receive the crystal debuff, which interacts with the rest of Endmin’s kit in the same way.
While an enemy is crystallized, applying a Physical status or Vulnerability stacks will immediately detonate the crystals, dealing Physical damage and freeing the target. Through Endmin’s talents, crystallized enemies take 30% increased Physical damage—a rare and extremely powerful debuff—and each detonation grants Endmin 30% Attack for 15 seconds.
A crucial interaction to note is that the 30% increased Physical damage applies to all damage sources, including the hit that triggers the detonation and the detonation damage itself. This allows you to stack attacks while the enemy is crystallized, then trigger the explosion with a heavy hit to fully capitalize on the damage window.
Endmin’s Battle Skill costs 100 SP and fires a cone-shaped Physical attack that applies Crush to all enemies hit. Crush behaves differently depending on existing Vulnerability stacks:
- Against targets with no Vulnerability, it applies one stack.
- Against targets that already have Vulnerability, it consumes all stacks to deal massive Physical damage scaling with the number consumed.
This makes the Battle Skill either a Vulnerability generator in a support role or a finishing nuke when played as main DPS.
At Potential 1 (unlocked through free progression), consuming Originium Crystals with the Battle Skill refunds 50 SP, greatly improving SP efficiency when combos are executed correctly.
At Potential 2 (also free), triggering the 30% Attack buff from crystal detonation additionally grants the entire team 15% Attack for the same duration, significantly boosting Endmin’s value in a support-oriented setup.
| Arknights: Endfield Endministrator Trivia
There is little doubt that the Administrator shares deep and intricate ties with the“ Doctor” from Arknights. It’s possible that future story developments will eventually reveal the Administrator’s true identity. Due to the Administrator’s character art bearing a resemblance to an emperor penguin, the community has also given them the nickname “Emperor Penguin.”
