Fossor

Recent studies by the Whitestar Institute reveal that some Ethereals' limbs carry notable features from their environment.
Fossor is a prime example of this — its strange forelimbs bear a striking resemblance to the drilling equipment found in the Old Oil Field region.
Although some suggest this is a camouflage tactic to deceive enemies, others have pointed out that Fossor's combat style is aggressive and direct, making it appear ill-suited for ambushes.
Some imaginative Hollow Raiders speculate it may have developed this form just to dig for minerals...
"When I caught sight of it from a distance, it seemed to be happily digging up the asphalt."
"When it spotted me, it didn't hesitate to charge straight at me, desperately trying to drive me away..."
"But I was just passing by! I had absolutely no intention of taking any of its junk!"

During combat, Fossor performs consecutive double-handed slashes.
