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.
I had a loaded shot gun in hand, thought I could one shot the pulmonoscorpius. I forgot to level up my torpor so this dude knocked me out straight away and then a pack of wolfs came to kill me while I was unconscious. Careful not to get knocked out!!
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!
