Strikethrough: Fixed
Blue: Crit Omega disagrees with- There are tonal issues throughout the essay that make it feel amateurish. I can do a line-by-like if you think it would help.
- Apollyon is misattributed to Shaggy when it was created by a user on EditThis and first used in a successful article by Clef.
- I'm also concerned that the definition of Apollyon is incorrect. I've never heard of Veil-Breaking capacity being factored in.
- The usage of your Theoretical classes may draw the ire of readers for injecting personal headcanons into an otherwise informative piece, thereby seeking to legitimize your classes as the same as real ones. It also kind of plasters your faces over the essay. The general consensus from authors will be that you need to actually try these classes out before trying to officialized them. Why should you guys get to add theoretical classes with impunity while everyone else has to get permission from you?
- The Avivit class seems to contradict the Foundation's usual behavior and is a perfect example of something that would only be accepted by the site if you could pull it off in an article.
- Why is there a distinction between a class' definition and description? A lot of the latter just seem to rephrase the former. I'd think it'd be better to just use the description section and include a brief summary of why the class is unique and valuable.
- Why do you attribute creators of classes? At a certain point, classes reach a level of popularity such that no one can really claim ownership over it.
- I feel like it's necessary to clarify that Ignosi is only applied to super high-risk anomalies, like DRO-0001 in the attached tale. Like, it's not applied to any mundane infohazard; it's a situation where the O5s burn all the evidence and use as many amnestics as possible.
- I worry that many classes which are technically viable for other articles, e.g. Maksur, ought to be treated as one-shots. This point, as well as my personal concerns about Ignosi, would be mitigated by getting author consent and advice for all the classes here if possible. I didn’t do this for my list because I tried to stress that a lot of these were irreproducible, but you seem to be marketing your list as general-use. I'd recommend confirming with authors if they're cool with their classes being treated this way.
- A couple of classes are attributed to that one deleted account as "Unknown". I think it'd be more useful to link to the forum post.
- People may not like the implication that these classes need to be used with ACS. If you want to group them based on Disruption/Risk, do that separately. ACS is still a fringe thing, and your essay will be read by a lot of newcomers who may be overwhelmed.
- Is there a reason you drop the descriptions of the final classes?
- Why are self-explanatory classes like Non-Anomalous not given an entry? Even if the definition is simplistic, you can still write about how to use them well.
- People may assert that this is functionally the same as my list with cooler formatting. I again suggest that you write about what makes each class unique beyond its definition; how does it interact with the world of the Foundation, how does it impact an article, etc.
- Can you clarify at the end that authors may remove their own classes at their discretion?
- Also, just a little request, can you downplay the effort that went into the esoteric classes list? I'm happy it was useful but I don't want to give off the impression that it's as hard as, like, being a forum critter or staffer.
Introduction
While the main classes of Safe, Euclid, Keter, and Thaumiel are sufficient to describe most items the Foundation comes across, some are more special and unique. In a word, esoteric. As such, many authors have chosen to create additional classes aside from these. Some, such as Archon, have received lots of use and are generally well understood by the SCP readerbase, but others are more obscure, often having unclear or sometimes completely unstated definitions. This essay aims to fix that.
In addition to listing various useful Esoteric classes and defining them, this essay contains detailed descriptions for each one, clarifies how they are different from similar classes, and provides an icon for each one to be used in the Anomaly Classification System. For organization, they are separated into Containment, Disruption, Risk, and Minor classes. There's also an appendix containing details on the ACS Fork and an icon gallery. Please note that despite the organization of this essay, you are obviously free to use any of these classes outside of the ACS format.
Keep in mind that this is not meant to be an exhaustive list of esoteric classes; that was made by Nagiros, who worked very hard to provide us with a comprehensive list, which was extremely helpful in the creation of this essay. Instead, this is meant to act as a resource for esoteric classes which may prove useful for users, but where their original definitions may be unclear or insufficient.

Obviously, this list is meant to be expanded upon with the additions of new esoteric classes. The following is the format used for new additions. There are also some conditions for adding to the list below that, depending on whether or not the class already exists.
++ Name of the class.
[[f>image (LINK TO ICON IMAGE) size="thumbnail"]]
**Creator(s):** User(s) who devised the class. This is not necessarily the author of the first article it was used in, but rather the user who came up with the idea.**First Use:** The first article it has appeared in. If it hasn't appeared in any articles, put down: ##blue|Theoretical##
**Definition:** Basic definition of the object class. By default, this is going to be the one appearing in [http://www.scp-wiki.net/esoteric-classes-complete-list Comprehensive List of Esoteric Classes].
**Description:** An expanded definition of the object class, clarifying how and when to use it, as well as what makes it unique.
Adding Established Classes
If your class already exists in a successful article, then it's most likely good to add, but keep two things in mind:
- Can it be used by other skips? Keep in mind that this essay is meant to help clarify how and when to use certain esoteric classes. If your class is designed for a single-purpose use, and is highly unlikely to be used by anything else, then it doesn't belong on the list. However, feel free to add your icon to the gallery below. (:
- Remember where the class actually belongs. Does it involve containment, disruption, risk, or none of them? Be sure to place your esoteric class in the correct category.
- Does it require expanded definition? A lot of classes aren't on this list because they're self-explanatory, such as Non-Anomalous.
Adding Theoretical Classes
If you want to add a theoretical class, one on a draft or just in your head, run it by Calibri Bold or
Omega Fallon first, to ensure it's up to scratch. Be sure to check out the guidelines in the "Established Classes" section above.
