Can only be obtained through stealing wild eggs and raising. Plan to have no life for four days because feeding them has to be planned, especially when raising multiple. Get milk from knocking out or killing female wyverns or alpha wyverns male or female. will only eat milk until it's fully grown (all 4 days if on official). Feel what it's like to have a newborn in real life except this experience only lasts a few days
I got a level 150 lightning egg and I was so excited to hatch the egg...that when I went to put the egg down I accidentally ate it instead. :( ps4 users: R2 ISN'T GONNA DROP THE EGG YOU'RE GONNA EAT IT LIKE ANY OTHER EGG. REMEMBER THIS. LOGIC BEFORE EXCITMENT.
