I use wyverns to tame these, as wyverns are not affected by the scare roar thing. Just find a place it can’t climb to get you, then just tranq it. Once it runs get on your wyvern and chase it, then corner it and knock him out. Not the most safe way but it works.
One thing which I like to use is a good flier, because once the yutys, start torpor running they cover quite a bit of ground pretty quick and the flier will help keep up, or a fast ground mount, it would also be helpful to ride a mount that allows yuh ou to shoot while riding.
It's over Anakin, I have the high ground!
You underestimate my power.
Don't try it...
It really is that simple though, they can't reach you or your flier on a big enough rock, so if you don't want to make a trap you can just shoot down from a rock or cliff once the carnos are dealt with. Be ready for a goose chase once it starts running.
