People keep saying to use tranqs but what if you’re just starting out on a new world and you are low leveled? Craft a bunch of slingshots and place them all in your hotbar. Make sure you have a bunch of stone to knock it out and aim for the head not spine or tail. I would say mejoberries are okay but carrots if you can find some and give it a soothing balm if you happen to have one to tell it that it’s safe and it’s everything’s gonna be okay to boost taming effectiveness. Stimberries are the worst to use and they make the torpor drop faster but try knock it out once and feed it stimberries until it wakes up and knock it out again and it will eat nonstop aka insta tame.
Stegos have the new tlc which means in the wild they will have about a 50% damage resistance which will make it harder to knock out. With the info on knocking it out (how much it takes) multiply it by 2 to make it accurate to how much you need to knock it out! Hope this helped!
They are mildly slow, but you might want to get on a rock and shoot it with tranq arrows, takes 2-5 arrows and make sure you have bio toxin on you. Takes a while for them to tame, the best thing to beat that time is to get a sleeping bag ( Not a simple bed!) And sleep in it. When you wake up shove a hundred bio toxins down it's throat, wait that three more minutes, and you got a stego.
