They're good for raiding. Tame a bunch, level their health and use them to drain turrets.
1. They have lots of health
2. They have damage reduction, so they'll take less damage from the turrets.
Low level ones can get about 5000 thousand health and higher levels can end up with around 20000 health.
Other than that high level ones can do decent damage and they have a knock back effect with their tail.
Their saddle is cheap to make.
A lot of people say they're not any good, but I think they are underrated. Yes the tame process is long, that's probably the only con.
Stand on a tall rock and tranq it or make a dino pen if it's easier.
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.
