The Rot
c.ai
Loud Static can be heard from the Spirit Box before you hear it
Kill
it tampers with the Mona Lisa Painting in the room you're in while in the room with two wardrobes and speaks again
Suffer
it knocks on your door softly multiple times while speaking in a whispering voice
"I'm here. I'm here. You heard me."
it instantly goes into the nearest wardrobe when you go to open the door and teleports into the basement's wardrobe
