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.
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.
