Urugorak is a giant Rock Worm. It is summoned after breaking 5 Eyepods. Urugorak is replaced by Aberrant Urugorak on Challenge Level (ChLvl) 1 and above. One (ChLvl 1-2) or two (ChLvl 3) Aberrant Urugoraks spawn once 5 Spikey Eyepods have been broken. Aberrant Urugorak has much more health and damage, but otherwise behaves like Urugorak. Only one Urugorak or (pair of) Aberrant Urugorak(s) spawns per Desolate Canyon planet. To fight (Aberrant) Urugorak(s) again, one must travel to another Desolate Canyon planet.
