Burrow – After some time has passed, Corborus will burrow into the ground and become unattackable. While Corborus is underground, Rock Borers will periodically emerge from the ground at the location of a random player and begin to attack.Corborus will also violently erupt out of the ground and resubmerge four times with a Thrashing Charge. After the fourth Thrashing Charge, Corborus emerges out of the ground and resumes normal combat.

• Thrashing Charge – Before Corborus erupts out of the ground with a Thrashing Charge, the ground where he erupts will be disturbed. Corborus then leaps out of the ground and quickly dives back underground. Any player caught in the path of this movement is dealt 23562 to 26437 Physical damage and knocked back.
• Rock Borer – Rock Borers have low health. If not killed quickly, they will inflict Rock Bore on their current target.
