I've seen people claiming that only super low level wyverns can be tamed without primal crystals, but that simply isn't true.

All you have to do is jump on their back (can be done from the ground), center yourself up where the wings meet the neck, start pumping it full of regular old crystals, and enjoy the ride. I tamed 4 of them that way today, and not once did I get thrown off or have the progress bar start to drop.

Knockout:

1. Build a wyvern trap

2. Agro it and lead it into the trap

3. Knock it out with tracks and go up to it to grab the primal crystal

Taming:

1. Find a good wild wyvern

2. Use a grapple and shoot its neck

3. When you’re hooked on, start feeding it the primal crystal

4. You now know how to tame a 140 crystal wyvern in 10 minutes

if you want to tame a wyvern within the first couple hours of your playthrough I recommend doing easy island note runs, getting to level 65, going to crystal isles with atleast 200 weight to hold the reg crystals, make a metal hatchet, get atleast 110 crystals, hop on the back of a crystal wyvernt then going prone near the head, and just keep feeding it and your done! (for extra help I recommend getting parachutes, just incase you fall)

How to tame: wait till it lands then climb on its back. Feed it some tasty crystal (They prefer the sweet, sweet primal type) it will take off don't worry you won't fall. DON'T LOOK DOWN!!! Go into third person. After the first feed wait a thousand years and feed it again (he will start getting hungrier after the second munch) wait till it's tamed, and hop on and ride it. After eating tons of crystal (please don't try eating crystal at home... Seriously) he then wants some fresh raw meat. (Don't eat that either) And that's how you tame. Hope it helped! -wise wise man

Easy tame: Hit level 65, grab 100 crystal and run to a wyvern, from my experience 100 crystal is enough for every level, next, climb onto the wyverns wing and onto its back (its very hard to do but is neccessary) then hit X and prone, lastly feed it a crystal... the time between the first and second feed can be up to 10-30 minutes but usually not that high, all the rest of the feeds will be within a minute of each other

The easiest way to tame a crystal Wyvern is to find a low level and lead it into a trap made from 4 behemoth stone gates then just tranq it out with tranq arrows. Once it's out take it crystal, keep doing this until you have a good amount (15+) then find a high level one and chase it until it lands then feed. Do this until it's tamed and then you have a crystal Wyvern. Plus they are good for charcoal.

right had bin looking for good baby tips but none being specific enough so i just went ahead and tryed it....this is for ppl who dont have crystal isles.... i aquired(stole) 2 wyvern eggs from a base that was inactive must have left wyvs on to mate.

got a daeodonlvl15 pumped all its lvls into food got it to 20k food. i put 4 troughs down far away from any other dino filled them with cooked meat set the daeodon up for passive heal and got the wyvs out

the low lvl wyv (67) had 500 food witch got it to about 10% mature.... once empty on food its health started to drop but the daedons passive heal keeps it to the top

there is a few seconds were the passive heal isent active but this is fine as the health only drops about 30hp before the heal is re cast

you can also imprint as it wants cuddles and walks so you can reroll if you get prime crystal as an imprint(reroll=pod chuck it back out till cuddles)

i was worried that at 0 food its health would fall while in pod and it doesent :)

CRYSTAL ISLES: Bring extra crystal just in case it glitches and you need to restart taming it. To get on it’s back land next to it on a flyer and whistle it to follow then jump up the wing and lay down in between the shoulders. That way when it flies straight up or down you will be good to go.=)
