These things are the bane of my existence. I was doing a perfect 150 allo tame in the redwoods, and I was off gathering prime. I get the notification, “You have tamed Allosaurus, level 150!” Two seconds later I get another notification. “Your Allosaurus level 150 was killed by a 120 Pulminoscorpius.” I run back to the taming spot, and sure enough, there is 4 Pulminos staring at me. I bola’d them and put campfires beneath them, and then lit the campfires. I ensured that they died a slow, painful death.
I tamed my eerie male scorpion on ark mobile during the eerie server event inside the poison cave. It was the best choice I ever made as he is now guarding my hatchery.
On mobile I recommend the following for stats if you plan to use a scorpion as a guard.
Speed is good at 230%
Melee at about 500% (just to keep those nasty wild Dinos spawning in your base in line)
Health about 5k (scorpions can be very easily killed if they don’t have good health in them.)
