Sword spiders were about twelve feet in diameter. They had sleek but hairy black bodies with dark-brown-striped fur. Their legs had chitinous plates with sharp ridges that resembled blades.
Sword spiders attacked with the sharp blades on their legs. They could also jump into the air and bring their legs together to impale an enemy. Additionally, their bite was venomous.
