The Official Up-To-Date DFS Slender Fortress Boss List

The boss types will be seperated like so :

• Chaser : These bosses will run after you, and attack you.
• Stalker : These bosses will stand still and looking at them/being in their field of view will give you "static", after enough "static", you will die. (Static affects how much your screen is shaking.)
• Paranoia : These bosses will stand still, letting them see you for too long will cause them to run towards you and kill you.
• Proxy : These bosses summon minions controlled by other players which can hurt you.
• Statue : These bosses will not move until you blink, or look away from them.

Sounds from SCP: Containment Breach.
Boss config made by ThatAverageJoe.

Intro sound : Minecraft cave sounds (Cave1 & Cave3).
Idle sound : None.
Kill sound : Femur Breaker Scream.
Static theme : Kevin MacLeod - The Dread
Tips : Obunga is a much harder version of the original Slenderman boss, he makes no sounds and it can be hard to survive him. Make sure to play carefully and not accidentally rush straight into him. His jumpscares will indicate the fact he's very close to you.

Tips : Having at least 1 other player with you is a good idea in case you get swarmed by the proxies. If you really need to, you can juke the boss by tricking him into starting an attack, then immediately running away from that attack, since his attack isn't instant, and he has the attack delay afterwards.

Chase Theme : "Your Contract Has Expired" from A Hat In Time
Tips : Snatcher can be a tricky boss to survive considering he has the Hat Ghost with him. Snatcher has a pretty big model as well as idle sounds which you can use to your advantage to avoid him. However if he sees you, run away and try to break line of sight as soon as you can, since he builds up static as long as you're in his view. Make sure Hat Ghost doesn't sneak up on you either (Refer to Hat Ghost's Tips)

Hat Ghost
Model and animations ported from A Hat In Time.
Origin : A Hat In Time.
Sounds from A Hat In Time.
Boss config made by ThatAverageJoe.
Boss Type : Statue
Spawns with: Snatcher
Attack rate : No delay (0 seconds)
Attack damage : Instant Kill in a radius
Static rate: 0.95 static/s
Boss Speed : 42 Hu/s
Sounds : "[Short High Pitched Laugh]"
Tips : Hat Ghost by herself isn't a big threat, however she's very dangerous when paired with Snatcher due to how she works. If you hear a giggle, turn around immediately, because there is a very high chance she is right behind you. If you keep her in your view, she will not move, however the moment you look away from her, she will move towards you and potentially kill you if she's too close, she will also move if you blink. Keep in mind that looking at her will build up static, so make sure to break line of sight with a wall as soon as possible as opposed to just staring at her constantly.

Tips : Make sure to use corners as much as you can when running away from him. Mr. X is a hard boss compared to the other chaser bosses. However you can use his 6 seconds long animation after killing someone as an advantage to either run away from him or run past him safely.

Chasing sounds : "[Evil Laughing]"
Searching Theme : "Queen Vanessa Found You" from A Hat In Time
Chase Theme : "She's Here" from A Hat In Time
Tips : Vanessa works like Snatcher, except she doesn't have Hat Ghost, her model isn't huge, she blends in with the darkness (except for her two red glowing eyes) and her idle sounds play rarely. The moment you see her/she sees you, run away and don't let the static kill you. She is very slow so you don't have to worry about her chasing you, just make sure there is no line of sight between you and her.
