Recommend getting a fjordhawk and some polymer. This works for most tames you get this way .The hawks don’t go to arrabiation[idk if I spelled that right- probably not] so if you want to get a rock Drake in the way I’m abt to share, try fjorder. So make sure the polymer (organic) is in one of your slots. Glide down to an egg of your desire (recommend using a spyglass) with your fjordhawk on your shoulder. Make sure it has tons of HP so it doesn’t die. You want to grab the egg and eat the polymer, quickly respawn at your base or wherever you’re storing eggs (if clearing out a trench, Deino nesting grounds, etc etc) The fjordhawk will bring your egg to you since you died with it in your inventory.

If you want to tame one of these you HAVE to do it this way or it won’t work. First you must find one and knock it out (I recommend you trap him with honey first and then knock it out. Second, once it’s unconscious press the button that’s indicated when you approach it to take primal crystals. After you’ve done all this you have to find one and if you’re a level 65 or higher (this is important) jump on his shoulder and lie down while u feed it the primal crystals, if you run out, feed it regular crystals and you’ve tamed yourself a crystal wyvern!

When raising a baby crystal wyvern.

Depending on your map settings, your baby might not even need to be fed! It also depends on your baby's lvl anything around 200 or up should not need to be fed more then once if at all.

It's better to feed it when it's almost starving 100-200 food.

Also stay calm! Over reacting is a no no, being a "Helicopter Parent" from my experience it usually gets the baby wyvern killed. It's better to lean on the "survival of the fittest" even if it's a little cold.

If you have a wyvern (any type) store primal crystal on them as it extends the decay timer.

You can jump on there back but is a chance you could fall off and die.

This did happen to me on my first attempt. Luckily I was able to find my body and recover my belongings..

So I just fed them, and followed with my fire wyvern. When they landed. Fed them again. Managed to get 3 pretty quickly.

The first thing you need for taming is to find the wyvern cave and locate all egg spawning areas. then you need to take a griffin because it is the only creature that can outrun them (just barely). Then Dive into the nest grab the egg go straight into the air and dive down finding the nearest exit. Requires wyvern milk to take so, trap and knockout females and take as needed, when fully raised they eat meat

When taming one of any breed, try to stand on the space where its neck and head connect. This will allow you to remain on the wyvern as if flying around to try and get away from you, some wiggling and spot correction may be needed but I've tamed 30+ crystal wyverns with this method

Some bad info here already

- You get only 1 crystal from a knocked out Lvl20 per charge, not 6. If you want more, knock out a higher level

- Of course you can transfer them and their eggs, done it loads with no issue, not sure why people think otherwise

- They can escape the two dino gate trap by flying upward

All of this is learned from experience rather than conjecture.
