Poetic wyvern information:

The wyvern is a lizard of the air,

To tame it's fury,

You must enter their burning lair,

It has three kinds: one's stormy one's toxic and one's fiery,

To enrage them is a deadly thought,

But if successful will not amount to nought,

If you find the glowing stone,

From Inside will come flesh and bone,

And lightning, venom, or fire,

But do not sink into the burning mire,

To get this treasure,

It does not bring pleasure,

It enjoys a nest of burning flame,

And milk of the beast from which it came,

But if you manage the impossible feat,

The wyverns's fury is now yours to tame,

If you hatch wings of thunder,

Your aim may often blunder,

But with its power,

It could topple the highest tower,

If you hatch wings of acid,

Your shot may miss,

But after that the air is no longer placid,

If you hatch wings of fire,

Your range is weak,

But your power is dire,

For the new players:

Ice wyverns freeze you which slows you down but it is the weakest wyvern

Fire wyvern does burn damage over time with breath attack

Poison wyverns can be very dangerous as their breath attack ignores armor

Lightning wyverns are the strongest wyvern in the game, however their breath attack costumes a lot of stamina

Tropical crystal wyverns aren’t the best for mele but they get a boost when touching water

Blood crystal wyverns heal themselves when they hit tigers with their breath attack

Ember crystal wyverns are similar to fire wyverns with the same breath attack

-Hope this helps!

Heres some INFO as we call it..

There are more than one type of wyvern, they are fire, poison, lightning, and soon to be a Crystal Wyvern with the Crystal Isles free DLC coming, they are going to be a passive tame. The types of Crystal Wyverns are base, tropical, blood, and ember.

The wyverns spawn in wyvern dens, and can be found in the Highlands for Ragnarok and the Snow Desert in Valguero (I only do free DLCs).

You tame wuverns by going into the wyvern dens and finding nests with eggs in them. Once you have an egg, they need 10-15 standing torches, 4-5 fireplaces, or 20 (atleast) campfires. Until they are adults, they need Wyvern Milk to survive. That is all they eat until then.

Wyvern milk can be obtained by knocking out a female wyvern and collecting milk from there. Alpha wyverns drop more than normal wyverns.

Wyverns pick up larger dinos than other flyers.

Wyverns can breathe fire for fire wyvern, lightning for lighting wyvern, and poison balls for poison wyvern.

Info!

I'm assuming if youre looking for tips you have already tried this yourself and it aimt going to well, and even if you haven't tried yet here's a run down.

1. Getting the egg.

Wyvern eggs are not to complicated to get, dont try on an argie or you will die. But on a pteranadon, Griffin, or tropegnathus, you can get as many eggs as you want. I know the tropeo can be annoying to tame but griffins are pretty simple and work fantastically.

2. Incubation.

Im not sure exactly how many A/C are needed to incubate a wyvern egg but I would set up a minimum of 15. Build the structure 2 walls high so that you can put celings above your A/C units. Place the egg on the celings as if its placed on the floor the wyvern might glitch into the foundations.

3. Feeding.

The method of getting milk can be tricky so there's always the alternative of getting a Daeodon and setting them to offset the starvation by healing the wyvern. If not just build a trap of 4 behemoth gateways and preferably a keypad.

This applies to Ragnarok only:

On the far west side of the Wyvern Trench there are usually an egg or two in the first couple of holes in the wall.

The coordinates (47.0, 51.4) (42.7, 55.4) (44.4, 58.8) and (33.5, 66.8) contain Ice Wyvern eggs. I can confirm the first and last have eggs, while I have only heard that the other two contain them.

Use a turret box if you don’t have a griffin pt or snow owl. Make a metal box with 4-5 turrets on it connected to a generator. Put lots of bullets in the turrets. Once you have stolen your egg get out on your flyer. When they follow you lead them to the box and they will get filled with lead.
