I tamed four of these the best way at least 4 me is get a rock drake Because they are much faster than a wyvern and go to a wyvern cave and find a egg if you find a egg glide to and jump off of the rock drake and grab the egg the wyvern will probably try to kill you but the rock drake is soooooo fast you can easily get uh way get back at base get a lot of touches and put the egg in it and watch it
