Best place to kill them is under karamja volcano. You can use cannon here. They are aggressive, so i don’t use cannon (being cheap), just afked with legendary pet, it take me several days. With legendary pet, it take the champ scroll for you.

Earth Warrior Champion
They are aggressive in chaos tunnel. I teleported with Varrock Armour to bork, earth warroir is next room to teleport spot. I afked with magic armour (subjugation) + Armadyl staff (air spell). It did not take me much time to get it. When they become non aggressive, just run to other side, come back.
