The Labyrinth Madman is an enemy in Bloodborne.
Tall, thin, and aggressive Pthumerians, the labyrinth madmen are always twitching and shaking as they gently pat the weapons they wield. Their mouths are almost always wide open and a few chains wrap around their bodies, implying that they were restrained in some way at one point. Labyrinth madmen come in three variations, Sickle wielding, Dual sickle wielding, and Corpse wielding. Each of them are incredibly aggressive and fast.
Labyrinth Madmen are found throughout various Chalice Dungeons.
Labyrinth Madmen are incredibly aggressive and dangerous enemies, able to cross great distances in a short span of time, as well as inflict massive damage. It is not recommended to attack them head on, as their, speed, aggression, and high damage make it very dangerous to do so. This makes visceral attacks a good way to deal with them, albeit a risky one. A much safer strategy (but one that can not always be done based on where the madman is located) is to sneak up on them from behind, preform a fully charged heavy attack, and then preform a visceral attack.
