Crystal helm! Not much different from the old one, honestly.
this Boulder class dragon resides solely in the depths of the hidden world, chewing on crystal and eating cavefish and lizards. Surprisingly docile in nature, it rarely attacks other dragons. Likewise, other dragons tend to avoid attacking it, as its sharp claws can tear off the carapace of a deathgripper in a single hit.
It disorients prey with a deep humming sound, before finishing off it off with one swipe of its claws. Its concussive sound blasts can rival a thunderdrums in strength.
each fin of its body functions like a tuning fork, bouncing sound vibrations around and using them to navigate and hunt. Despite its strong echolocation ability, it is, in fact, mostly deaf and depends solely on these vibrations and strong sense of smell to get around.
despite being surprisingly fast in air, it rarely flies. Preferring to stay on the ground. It lays eggs in crystal, stays until it hatches and the child can fend for itself, than continues its solitary lifestyle, meeting other Crystal helms only to reproduce. Despite this, It can communicate with others members of its species from long distances and has thousands of different communication calls.
there is no difference between male and females.
