the rock hydras skin helps it to hide in the etain desert. It uses the desert to catch it's prey and when it's prey is close it will use it's poisonous breath to kill the prey. If any one takes it's gem from it's chest it will crumble into dust and will hunt the person who has it's gem until next autumn if the gem is not used in a magic and if no one takes the gem from it. If it was wild it would grow cracks until it is no more until next autumn.

Wow, I think this is the first hydra here! Very nice! Good luck!

actually it is not, there are 5 kinds of hydra I believe.
Balance, Fire, Water, Earth, and Air
