There is a Mod called "Crystal wyverns regraded"

that adds crystal wyverns to every map that has

an wyvern trench. Taming is like a normal wyvern:

steal egg

-raise Baby (with primal crystals(i guess u get them from adult crystal wyverns)

-imprint

Utility:

They are Just Like normal Crystal wyverns but smaller and they have a dive like griffins

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

Note: This tip is about the heir counterparts, and is for defence and escape.

The crystal wyvern heir variants are regular crystal wyverns with crystal skulls on their heads and are highly aggressive. These heirs are what lay the crystal wyvern eggs, and the eggs hatch into normal crystal wyvern. They can be all the way to the level 225 on a regular server where 150 is the max level. When encountering, you can fly away if you have a fast enough mount with you, or you can face them. When attacking, I highly recommend you have a hogh level crystal wyvern to fight with as this is one of the only other flyers on the map that can rival these creatures. They spawn at the desert wyvern hive, which will have hexagonal catacombs in and around it, just as the trenches in scorched earth and other maps do. If you are attempting to steal an egg, have a fast creature and be aware that every other heir wyvern in the area will aggro on you. If this tip was helpful, up and let me now.

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

TRANFERRING IS POSSIBLE! I uploaded all 3 of my passive tamed crystal wyverns into the obelisk & transferred them to Ragnarok & The Island w no issue whatsoever. I didn’t try cryopod transfer, as doing that makes me nervous & I don’t like to risk it. But transferring through the obelisk works.

Basically if you like the glow of wyverns you would want to learn some stuff I found out so...female wyverns glow brighter if needed to know.. they also seem a bit bigger. Now besides that I wish on tropical wyverns we could swim in with the wyvern it needs a bit work for how they function...but otherwise it’s good!

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 :)
