Characters

Introduction

The character database covers every playable operator in Arknights: Endfield with the details that actually change how a squad performs: element, class, weapon type, faction and rarity. Because every squad is four operators sharing three skill gauge charges, a character's value comes from how their kit interacts with the rest of the team rather than from raw rarity. Each entry notes the role the operator fills, the weapon pool their signature gear comes from, and what they do well in practice. Each entry also notes the practical caveat that matters most in squad building: an operator contributes value only when the other three slots can support them, so a strong kit placed where the team already has coverage adds far less than a modest one filling an empty role.

Core Mechanics

Operators are defined by three axes. Element decides matchup value across Physical, Heat, Cryo, Electric and Nature damage. Class decides the squad slot, covering Vanguard, Striker, Guard, Defender, Caster and Supporter roles with distinct responsibilities in the four-operator formation. Weapon type decides which supply pool their upgrades come from, and the five types are Sword, Greatsword, Polearm, Handcannon and Arts Unit. Rarity, running from four-star up to six-star, sets the ceiling on the investment curve. These three axes interact rather than stacking independently. Element decides whether a stage is winnable at all, class decides which job is covered, and weapon type decides where the upgrade materials will come from, so a roster is really a matrix rather than a list.

Advantages

A structured database answers the questions that actually block progress: which element covers a stage's enemy composition, which class the squad is missing, and which weapon pool the operator you are building draws from. Because rarity and role are separated from performance, the database also makes it obvious that a well-invested four-star in the right role beats a six-star placed where the team already has coverage. Because the database separates potential from readiness, it is straightforward to see where rarity is genuinely doing work and where it is not. A four-star filling an uncovered class slot frequently outperforms a six-star duplicating coverage the squad already has, and the entries make that trade visible rather than implied.

Challenges

Database entries describe kits, not verdicts. A character page cannot tell you whether your specific four-operator squad needs that operator more than a different pick, because that depends on what you have already built. Numbers are also drawn from community testing where official values are not published, and launch window data is thinner than it will be after a few more versions of community verification. Entries are also written for the version they were checked against. New versions add operators and occasionally retune existing kits, so an entry that has not been revisited after an update should be treated as provisional until community testing catches up with the change.
