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.
Depending on your level and Materials you have. large bear traps are pretty cheap to craft. Craft five or more depending on how comfortable you feel.
And use any method of tranquilizing you like.
Tip: when your timing something it never hurts to go a little bit above of what you need in materials.
1. Find the fluffy t Rex. When you find one make sure you’re pretty close but not too close for it to notice you.
2. Place down all the bear traps in a line.
3. Once all your Bear traps have opened. Try to get the attention of the fluffy t Rex. Just shoot it once or go up to it (if you’re brave enough). Once you have its attention run to the first beer trap in the row of bear traps you’ve place down.
4. Once it’s caught in the bear trap you wanna run to the last bear trap in the row. You Want to have the bear traps between you and the fluffy t Rex. And that way you can start shooting it. and as it breaks each bear trap and try’s to come toward you it steps on another Bear trap getting it’s self stuck.
And depending on what tranquilize method you use you probably won’t have to worry too much about it running away but they’re pretty slow. I use this method for almost every dinosaur I tame that can fit in a large bear trap.
What’s needed: two dinosaur gates ( any material I use wood ) two dinosaur gate doors. (For best chance bring extra gates)
Go on a flying Dino recommended arg or wyvern, find a yuty and place one gate in front of it then place the gate door, place the other gate behind it really close and then place the gate door. This can take multiple tries being you have to know what your doing.
Warning: your Dino that your flying on can get scared very easy and loose control and fly away, to not loose it stay mounted and if it flys away you will be on it.
