Ark mobile: No creature land or water aggro on it. But if you strike though the creature will go active and strike once or twice but will again go passive. But again if you unmount or shoot arrows from mount it will aggro on you. Helpfull on farming chitin, hide and meat on southern islet cave. Overall good mount fast, good stamina, fast attack with torpor, and swims fast in water. Will outswim almost everyone land based creature in water. Helpful if on run or traveling fast. Pump Health, stamina and meelee. Dont jump in between its claws. U may get stuck in tight spaces. And jumping on sting gives damage. And you can tame it in cave. Taming on cave doesn't work in case of Northern Hollow. So don't waste time there for this.
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.)
