I don't know why the guy saying they're not affected by Bolas is at the top. I just hit a level 5 wild in the mountain area with a bola right in the legs and it froze in place perfectly, no issues. BOLAS WORK, BUT YOU HAVE TO HIT THE LEGS, THE THIN SKITTERY EASY TO MISS LEGS.
Taming these things at low level is no problem! A level 150 only takes 18 tranq arrows with a regular bow, and you can bola them, which helps hold them in place. Not to mention, they will eat the spoiled meat you don’t want, and can also be a powerful bodyguard for you until you get something stronger.
Bola it, shoot it in the head with tranq darts, feed it spoiled meat! A very effective and easy tame. Be careful though, they're hard to see in grassy areas. I was taming a sabertooth once when it came up out of nowhere, I went unconscious before I could even run away. It took me 5 tries to get my stuff back from my dead body because the scorpian was always there. In the end, surpinsgly, my sabertooth survived the taming process and I ended up taming the scorpian right after!
