Ok... It's just out of punching range and is fairly slower than you when you run... So if you're a noob you are either 1. Hitting it with your pickaxe and killing it or 2. You are running away after you found out it wasn't what you thought it was. If you were punching it then congrats you can tame them easily! Just don't use a club they have more range then. Hopefully this helps noobs knock out dilos (I have an army of them but there's a sneaky raptor trying to kill me I'm gonna call her "clever girl", and I don't want her to die)
