Please add how much milk is needed.

If you are looking too get a lot of wyvern milk you need too kill a alpha wyvern and harvest it's body it will give you 50 milk

Will they be added to ark mobile?

I suggest you build a trap with pillars to where your argy could get out but wyvern can't then have a key pad to close gate then shoot with tranquilizer arrows or darts

Use cryopods so you can finally sleep at night!!

Add Wyvern nest locations on Ragnarok and Scorched Earth map! Upvote so Dododex can see!

Hatching: you need a very hot area. Use standing torches in a circle (10 to 15). Or build a room with a lot of air conditioners. Imprinting and baby survival: Make sure you have wyvern milk. They only consume that for food when babies. You have to manually feed it to them until they are juvenile. It is also the only food they will ask for during care. Also set the follow behavior to lowest and disable wandering in case they wanna walk. Wyvern milk can be obtained from knocking out a female wyvern and looting her. You get 5 milk. Doesn't respawn on same female. Alpha Wyverns can be killed and looted for 50 milk. Milk can be stored in preserve bins but not fridges. Wyverns have 3 attacks. 3rd attack changes from flight to ground. Primary=bite, secondary=breath, tertiary(flight)=pick up creature, tertiary(land)=wing flap that pushes back enemies and knocks down trees(collects thatch more than wood) No saddle needed. Friends can stand on back. Dismount doesn't throw you.

To fight posion wyverns use a gas mask.

The highest wyvern egg you can get is 190.get higher level eggs to hatch rather than low levels as high levels have more food and need to eat less often.

Wyverns can harvest wood and thatch with wing flap, also the stumps around redwood area on Valguero, (untested on other maps) will harvest sap.
