Hunters take low damage because they are small, so the monster throws the hunter around rather than breaking them. Think insects - if they fall they are fine, but if you fall you are injured. Gavios is massive and so it is crushed when dropped from a large hight. Also, the force that akantor uses to spin gravios up and over probobly broke gravs neck.
