Gargoyles stone form

These gargoyles are blood thirsty creatures that are stones in daytime and monster on nighttime. They are Lord Garthalamir's guards on nighttimes they roam Blackthorn kingdom on night. When they saw strangers they will attack you and kill you, after they kill you they will eat your flesh. After the sun rises they will back to their sanctuary and the will turn into stones. (if you want to add more its ok to me)
