The Drillhead is one of the signature monstrosities created to serve Father Johann of the Cult of Metamorphosis. These sand worms have been grafted with strange drills that allow them to burrow and ambush their prey with frightening efficacy. They also boast two different behemoth sized frankenstein like creatures. While other factions have abominations with unique abilities, the Juggernaut and the Nightmare Juggernaut receive special augmentations to compensate for the lack of the "Skarrd Gifts".
The logo for the Cult of Metamorphosis features a Drillhead on the familiar Skarrd beveled square back plate with a rust colored scheme.
