** The effectiveness of shift skills (those that push or pull enemies). The amount the skills will move enemies is expressed in vague terms like "slightly", "moderately", and "significantly." To make things worse, enemies have a ''weight'' associated with them which will modify how much they'll move. And while the weight for some enemies are intuitive (larger enemies will be less affected), some are less so and this stat is hidden.

** The "Price of Peace" ending of "Mizuki & Caerula Arbor". [[spoiler:Mizuki performs a HeroicSacrifice to defeat Ishar'mla and pacify We Many, permanently ending the Seaborn threat. However, Terra remains a CrapsackWorld, and in addition to Mizuki's sacrifice, all of the Abyssal Hunters are dead, except for Skadi, but her mind has been so broken by Ishar'mla that all she can do is sing to herself in a secluded oceanside cave.]]

*** Ending 4: [[TrueEnding Silent Chapter]] - [[spoiler:The TrueEnding where Rhodes Island found and confronted the Playwright responsible for the Plays of the Crimson Troupe reveals that he has trapped everyone in a GroundhogDayLoop after the Mouthpiece's "ad-libbing" ruined his plans and kept everyone trapped in a loop until he could write a satisfying ending for himself. When he is later defeated and Phantom rescued, the Playwright reveals that the story and the events of "Phantom and Crimson Solitaire" has already gone exactly as he envisioned. Rhodes Island rescued Phantom successfully, unaware that the Troupe and Playwright himself already planted a seed of the Troupe Master's brainwashing in Phantom that will successfully turn Phantom into their sleeper agent TykeBomb and fulfill the HappyEndingOverride that the Troupe Master loves to see.]]

*** Ending 2: RidiculousComedy - [[spoiler:After rescuing Phantom and defeating the Big Sad Lock, the Mouthpiece appears before Phantom and Miss Christine.]]

** ''Mizuki and Caerula Arbor:''

* NotDrawnToScale: The chibi sprites for all operators are of roughly the same height, despite the potentially huge disparity between two given characters in-universe. Really, there's no other way to explain how the sprites of a 135cm-tall Shaw is just slightly than Hellagur, who officially ''towers'' over her. Sometimes this isn't even consistent, with Durin and Myrtle's sprites being of different height even though they are both 131cm tall in their profiles.

** When Lava gains an alternate unit version, that version is called Purgatory. However, they're effectively still considered a same unit like the aforementioned friend's support and can't be deployed together both in battle and in the base. The same would apply to future alter operators such as Skadi the Corrupting Heart, etc.

** Juggernauts, Mushas, and Reapers have elemental damage as their weakness. While they can be healed from normal damage with their attacks, the fact that Medics cannot heal them directly means that Wandering Medics are unable to heal the buildup of elemental damage, leaving these melee Operators very vulnerable to enemies or environments that deal elemental effects. The sole exception is Highmore, a Reaper who directly heals elemental effects with every enemy she hits.

A spinoff[[spoiler:/seeming StealthSequel]], ''[[https://endfield.hypergryph.global/en Arknights: Endfield]]'', [[https://www.youtube.com/watch?v=oo0deb64GNw was announced]] on March 18, 2022, with a [[https://www.youtube.com/watch?v=iWUkSZyjUyM second]] [[https://www.youtube.com/watch?v=JcsOm6WSBDA set]] of trailers released on October 26, 2023. It is currently in the closed beta stage.

* ForegoneConclusion: Because of "Code of Brawl" story details, a lot of things in the Reunion Arc's conclusion are spoiled by the event. To wit; [[spoiler:Talulah's aim to crash Chernobog on Lungmen is thwarted. the Rat King is still in good term with Wei despite Wei's action, because the Rat King's own scheme counteracts it. Ch'en, Swire and Yuhsia's attempt to integrate the slum properly into Lungmen Downtown succeeds]].

** Cement quickly got associated with the meme "That's concrete, baby!" when she was first introduced to the CN server and Global players saw her for the first time. During the global release of Episode 12, with Cement making her Global debut, her Trust Tap voiced line in the English dub directly references the meme as she says this outright about her shield.

* WhamShot: [[https://www.youtube.com/watch?v=IAY3qnoBxHA The Concept PV]] that is released to commemorate the release of Chapter 10 in the Chinese server shows [[spoiler:a silhouette of Theresa walking under Theresis' shadow and the final shot of the PV shows a now resurrected Theresa standing next to Theresis as they overlook Londinium]].

The world of Terra is on the brink of ruin. An infectious, incurable disease known as oripathy has been spreading across the populace for the past several centuries, based on contact with the seeming wonder material originium. Originium can power devices and achieve effects that are, for all practical purposes, FunctionalMagic; but overexposure causes oripathy, in which the afflicted's tissues are slowly transformed into a form of originium that is even more virulent than the "naturally"-occuring mineral. Sufficient crystallization, naturally, results in death. Those with oripathy became known as the "Infected", and are outcast and feared by the general public. In response to the rising oripathy pandemic (as industry begins to rely ever more on originium's incredible generative and transformative properties), many of the Infected banded together to fend for themselves, with only each other to rely on.

You awaken as the Doctor, a master tactician and member of the group "Rhodes Island", a private medical company based on a small [[BaseOnWheels nomadic city]] of the same name; Rhodes is composed mainly of Infected, drawn from the world over and all walks of life, who seek a cure for oripathy and to end the stigma against the Infected, and in a world as dangerous as Terra has become, maintains a defense force that it has had to use far more often than its leadership would entirely prefer. Severe trauma has resulted in the loss of your memories, and you are greeted by utter chaos: on the brink of a Catastrophe (the manifestation of originium deposits via sudden natural disasters), the forces of the Reunion Movement, a band of Infected who seek revenge on the society that shunned them, have suddenly struck back against the Empire of Ursus, seemingly hell-bent on driving the entire city of Chernobog into the Catastrophe's heart and annihilating the city in the process. With no one but your loyal, seemingly-long-time compatriot Amiya and your fellow Rhodes Island Operatives to guide you, you are now tasked with leading the charge to your freedom and uncovering the truth behind the mysteries of your past and future.

** There are three damage types: Physical, Arts, and True. Physical damage is resisted by DEF; if the attack exceeds the target's DEF it deals full damage and if it doesn't the attack deals ScratchDamage. Arts ignores DEF but is resisted by RES, which reduces the Arts attack by a flat percentage. Physical attacks tend to be better against numerous and less armored enemies while Arts attacks are better against tough and armored opponents. True damage ignores both and deals full damage directly to HP, as well as bypassing most damage ignoring or dodging mechanics.
** Elemental Damage is a different type of damage that doesn't initially affect HP, but gradually builds up as a meter on the affected target, triggering a severe effect if the meter maxes out. The Wandering Medic branch is specifically designed to counter this by reversing said buildup, while Ritualist Supporters can uniquely turn this on enemies. The current types of Elemental Damage include Nervous Impairment,[[note]]Inflicts massive True damage and a lengthy stun[[/note]] Corrosion,[[note]]Deals heavy physical damage and inflicts a permanent stacking DEF debuff each time it triggers[[/note]] Burn,[[note]]Deals massive Arts damage and temporarily reduces RES[[/note]] and Necrosis.[[note]]Deals Arts damage over time and drains SP while preventing skill usage; on enemies, it'll inflict a decaying ATK debuff instead of SP loss[[/note]]

* DeathWorld: Terra in spades. Not only are Catastrophes city destroying disasters that happen at random, they also leave behind a mineral that causes a highly lethal transmittable illness, the ocean has a race of hostile sentient hive minded monsters, and last but certainly not least are the actual demons wandering the land that start at army killer level and grow stronger just by people knowing about them. How any form of civilization survives on this planet is a mystery.

** You can only have twelve members on a team, plus one from either your Friend List or a random stranger. Of that, most of the time only eight are allowed to be deployed at the same time in the field; the 1-star Robot operators and Nearl the Radiant Knight (with her second skill only) are the exceptions to this rule because their innate Traits (skill in Nearl's case) allow them to bypass the deployment limit.

->'''Kal'tsit:''' In the past few years, Originium has become the lifeblood of the world. It first gave birth to greed, power, pain, hatred. And soon it breeds countless monsters - us. We were deprived of our identities, and were named -- The Infected.\\

* {{Expy}}: Let's see. Marthe is a big-name brand of clothing originating from Kazdel, the FantasyCounterpartCulture to Germany, is extremely popular in Ursus, and their best-selling products are tracksuits. Sure sounds a lot like [[https://en.wikipedia.org/wiki/Adidas Adidas]]. In fact, even their [[https://gamepress.gg/arknights/sites/arknights/files/2020-02/2020%23marthe_InvertShadow.png logo]] looks disturbingly similar to Adidas' 3-stripes design, only inverted and having the shortest line filed off.

* FadingAway: This is how operators disappear from the field once their HP gets depleted.

** Operator outfits are only available to purchase during the one-month period in which they're in the shop. Once this sale period is over, the costumes will leave with it and no amount of Originite Prime can get them back short of the developers releasing them again in the future.
*** Thankfully, most outfits become available again for purchase. The outfits are usually rerun every year and the older outfits are in general available in every event with a limited banner.

** Beating Operation 3-8 presumably allows you to play Main Story chapters that take place after Chapter 8, the end of the Reunion arc (such as Chapter 9).
