Simple go in with a pterodactyl make sure all the wyverns died or are fire and no alphas look for a female after you get the egg I recommend on ragnorok there is a hidden cave in the plains where you can set up a base don’t like making ac s well use a bunch of fires and torches now look for a female get 4 behemoth gate ways get a rifle some darts or tranq arrows and then get I recommend 200 wood for the fire then place down the egg and boom also people don’t make it specific on which to look out for the good and bad way try to dodge poison wyverns avoid lightning and just stay a distance from fire and ice!
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.
