| 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. | |
| Rock Bore | Rock Bore can stack up to 10 times. |
