Overview of Main Story Chapter Unlock Conditions in Arknights: Endfield

In Arknights: Endfield, the progression of the main storyline is not linear but is restricted by a core metric—Permission Level. Simply put, the primary requirement to unlock subsequent main chapters is to increase your Permission Level. It acts like a key; only by reaching a specific level can you unlock the door to the deeper secrets of Talos-Ⅱ.

Permission Level: The core key to unlocking the main storyline

Permission level is a comprehensive metric used to evaluate an Endministrator’s progress in Talos-Ⅱ development within Arknights: Endfield. Early main story missions will guide you through its importance, but as chapters advance, the required permission level for missions will gradually increase. If your permission level is insufficient, you will be unable to accept or continue related main story missions.

The main methods for upgrading permission levels are diverse and closely integrated with the core gameplay of Arknights: Endfield.

· Complete main and side missions: This is the most direct source of experience, so prioritizing the advancement of currently available main missions is crucial.

· Complete various commissions: including daily and weekly commissions, providing a stable source of permission experience.

· Exploring the map and unlocking anchors: Gaining experience rewards by venturing into unknown areas for the first time, activating TP Point and collecting treasure chests.

· Base Construction and Production: Completing building upgrades, arranging production lines, and successfully producing materials in the infrastructure will also contribute significant authority experience.

Therefore, to continuously experience the main storyline, you cannot just focus on the quest list. Actively exploring the map, managing your base, and completing daily tasks to comprehensively advance your progress is the proper way to unlock chapters.

Development Plan: Paving the Way to Advance the Main Storyline

Unlocking chapter missions alone is not enough; you also need sufficient combat power to complete stage challenges. A well-planned development strategy is another cornerstone for smoothly advancing the main storyline. Your lineup and resource allocation should be dynamically adjusted according to the game's progression.

During the early development phase, the goal is to steadily progress through the initial storyline. It is recommended to use a balanced team composition such as Chen Qianyu, Angelina, Endministrator, and Perlica, prioritizing the enhancement of character levels and skill levels. At the same time, be sure to focus on the ‘Gear Assembly’ in base construction, unlocking and upgrading it promptly to produce higher-level universal gear, providing fundamental combat power support for the team.

In the mid to late stages, as chapter difficulty increases and more characters become available, it is advisable to focus on 1-2 specialized teams (such as Cryo, Melting Flame, or Physical teams) for deep investment. Concentrate resources to upgrade the core DPS characters' skill mastery to critical levels, which often results in a qualitative leap. At the same time, begin farming for exclusive weapons or optimal trait matrices for your main characters, as this is key to tackling high-difficulty late-game main story content.

The culture system is a core aspect of combat power enhancement. culture is divided into level up, ability matrix, current potential phasre, gear bounus and exclusive weapons (EX weapons), with EX weapons always being gold-tier legendary quality, representing the ultimate goal for characters. The essence of the culture system lies in the synergy of the matrices: it is crucial that the attribute types provided by the matrices correspond to the inherent attributes of the weapon to be effective. For example, a weapon that increases critical rate can only be embedded with matrices that boost critical damage, critical rate, or similar attributes. Incorrect combinations will result in the attributes failing to activate.

When facing uniquely mechanized bosses or extreme stages in the main storyline, flexible adaptation is essential. Manual control, on-the-fly team adjustments based on enemy traits, and fully leveraging skill synergies and counter relationships between characters are crucial for success.

In summary, the unlocking and progression of main story chapters is a path driven by permission levels and paved with solid development and flexible tactics. By maintaining good resource planning and time management, you will steadily advance into the heart of Talos-Ⅱ, gradually uncovering all the secrets hidden within this land.
