A hamster is put into the microwave in season seven - probably many others, but that's the first that comes to mind for shock/gore factor

There are various animals that were put into microwaves, or made to seem like they were put into microwaves

The first thing that comes to mind is in Season Seven, where a man who was presumed to be a drug addict is kidnapped off screen, before the season starts. Our main characters visit a deranged pastors house, and find him strapped to several needles pumping drugs into him to a horrifying point.

There's a scene in season 3 (I forgot which episode, but it was later in the season) where a woman attempts to give herself an abortion with a clothes hanger. It fails but it's a very graphic scene

In season seven, one of the main "protagonists" has several panic attacks due to her phobias

Twisty the clown

Season One and Season Five are almost entirely centered around haunted places and ghosts

Kyle Spencer (season three) and his mother - it is also non consensual

The entire show is pretty much gore mixed with jump scares, mixed with a heavy helping of 'whaaaaaaaaaaaat?'

The snake coming out of the mouths on covens cover

Season One - Episode 1 or 2, there's an entire scene that's based around strobe lighting

Madison flips the frat bus

Vivian Harmon dies while giving birth to a demon baby

Happy Endings are not in the realm of this show. More bittersweet than anything. There is always something that happened to make the "victory" very sad, ruin it, or not have a victory at all

Ben harmon cheats on his wife

Violet harmon committed suicide by overdosing on sleeping pills

Dandy drowns, Gladys drowns, Chad Warwick drowns, Nan drowns

During Madison's monologue about trying to feel something after coming back to life she mentions not eating for days to look good.

Fiona has terminal cancer

Vivien has a miscarriage

Violet self harms

Violet Harmon overdoses. There is a deranged pastor in Season Seven that hooks a man up to a machine that pumps him with illegal drugs to the point of near death

All of Constance Langdon's children, all of the Countess' children, and many more Especially Kyle Spencer, that was absolutely nauseating

Lana has to get electro therapy because she is a lesbian

Season Two completely ruins Santa or the idea of Santa forever

Someone is tricked into being trapped in a tomb sealed with brick as well as a woman being immortal and trapped underground for centuries

Myrtle gets burned alive along with many other witches in the sieries

Lana has to be in a mental institution, just because she is a lesbian

Season Eight - Michael Langdon

Meadow in Season Seven is the first that comes to mind for me

Liz Taylor in Hotel is misgendered many times

sister mary eunice is possesed by satan

Lana gets raped by bloodyface

Violet Harmon in Season One is stalked by Tate Langdon (a ghost) who can turn invisible. He follows her around and watches her sleep on several occasions

In the first episode very early on, a woman is seen going to an attic or basement and seeing her slaves after bieng tortured. It is very graphic.

A character is made immortal, buried alive, and told she'll be there basically until the end of time. The character is absolutely repugnant in every way but the scene BADLY triggered my claustrophobia.

Season Three has quite a few hangings

the whole 2nd season

The entire premise of Season Eight

In Season Seven, there is a place where a deranged pastor hooks a man up to machines and pumps him with multiple drugs until he almost dies. Lots of others, probably, but that was the most disturbing to me.

The entire show. Nobody is safe

Madison Montgomery in Season Three has a few lines in a whole big speech about it.

Vivien Harmon in Season One is the first that comes to mind

Season Three - Cordelia Goode takes a pair of gardening shears to her eyes to regain a magic power called "The Sight" Season Three - Cordelia Goode is attacked with acid and blinded as a result Season Three - Myrtle Snow uses a melon baller and takes out a few people's eyes to give them to Cordelia Goode

Tate Langdon in Season One shoots up a school - Made to reminisce people of Columbine

Season Five - Liz Taylor (a transgender woman) is the first that comes to mind. She is cornered and called slurs and other things multiple times

Violet Harmon in Season One is the first that comes to mind, but there have probably been others
