There should be monster that is able to dig underneath ground. Kind of like a mole. Maybe give him a ability to dig tunnels in the map use that as his stamina. make the hunters be able to go into his tunnels and follow him. Also make him be able to leap from his tunnels and do a body slam on the ground. Maybe throw a rock at the hunters or maybe like a storm of rocks get thrown at the hunters. Maybe make him hit the ground and make a boulder knocking up the hunters.
Actually, one of the first monsters, the Scorpid, had this ability. But it wasn’t fun to play against and was scrapped. You can see it in action in the development thread.
