If you want to to tame the legendary dodo you will need:
A tek trap
A thorny dragon because it deal good torpor
When you have all this, lure the dodo into your trap. Do be aware it is the fastest, strongest, and smartest creature in all of ark. And then you whould have a dodo! (If you couldn’t figure it out it’s a joke.)
Extremely high aggro rage, so using a tanky flyer like a quetzal is recommended. If you are using a trap, build it out of metal as, although they can damage it, takes a lot of tome for them to do. It takes about 20- 35 tranq darts to knock it out, and once it is, its torpor decreases extremely fast. Anything but exceptional/giga kibble is extremely useless, and even with it, needs about 500-1500 narcs to tame it.
