Im s lvl 51 and it is so hard to get all the resources they should make it easier to tame.

Use rare flowers to get it out of the sky, then bola and tranq it. Works like a charm every time.

I am on Ragnarok and I was able to get it stuck in trees. They get stuck in trees very easily if you're away from your base. Don't bring a high level back to your base or you will lose everything lol. I used about 60 narq arrows to keep it down. If it wasn't for Ichy birds bugging me non-stop it would've been a very easy tame. Took about 1 hr. It was a level 25 I think. Still this thing is a farming beast. Good luck! They hit like a bus, so be ready to die.

I tamed one using my argy with 10k hp. I built 2 metal gates around a bear trap (a common trap a lot of people use.) However I kept messing up and having to demolish my gates. After making multiple mistakes I found out that metal billboards work too. (the big signs. not the little ones.) Also, my 10k hp argy couldn’t tank it for long to lead it into the trap. The giga I tamed was lvl 25 and it was still hitting for like 400 dmg per bite. You’re never invincible with these things. I brought about 600 tranq arrows and over 1k narcotics (overpreparing is much better than underpreparing.) I lead it down to the beach to trap it. Its a flat area so it works well. Lead it into the bear trap, place billboards or gates behind it, and then shoot it like crazy with tranqs. (it should be 100% stuck by the time you start shooting.) Also, honorable mention! IT RUNS FASTER THAN ARGYS. I havent tried with Ptera but they have trash health anyways.

You can wear gillie to make them less agressive
