Decided to make this because the original Bone Spider found in the Catacombs of Sotha Sil Expanded isn't exactly what I would call nope-worthy (get it?). Technically, this can be used for other stuff, though, such as if you wanted to add it to some leveled lists and give it the Daggerfall skeleton scream. Feel free to do so. Or not, because that sounds scary.
