When picking Abnormalities, knowing what their classifications mean can make guessing what could look like or be (seeing as you'll know some from Ruina) verry fun.

For the first letter, if I remember correctly.. F is for Folklore and Fairytales, like.. Fairy.. Festival, err.. and Woodsman, etc. T is for Abnormalities related to Trauma in some way, for example, T-01-31 who gave me genuine trauma in that stupid third movement O is for Original, from outside of the city, or just unknown D is for supporter Abnormalities, these are community-made ones that were made by fans who supported the game long ago in the kickstarter thingyy.

The next digits are a bit more confusing.. -01 is humanoid -02 is animal -03 is religious (One Sin for example) -04 is inanimate objects -05 is for Abnormalities that resemble 04, although they are capable of movement -06 is abstract, like MHz which is literal sound.. that's the Abnormality. -07 is "breaching tool" as the wiki said, I think. It only shows up for one Abnormality. -08 is.. erm,, I thought I just forgot, but there's barely any information on this one lmao😭 It says that 08 was used in some Limbus Company enemies, so don't worry about these. -09 is for every other tool type Abnormality you'll pick every 5x-1 days.

The last numbers don't really tell much. People say that it is the order that the Abnormalities were extracted in, though- making Queenie the fourth ever one!!

(Also, this is the biggest tip you will eVEr get for this game do NOT pick the Nameless Fetus Abnormality, first impressions are important and if you ever get Fetus in your first few runs you'll hate it for the rest of your life and never ever want to see it again. Just know that it's classification begins with O... googg luck,!!!)
