How to tame a Wyvern; Solo Version. Doesn't apply to Ice Wyverns
1) Tame a fast flyer usually a griffin or pteranodon with good health, stamina, speed, and melee damage.
2) Stock a good gun with lots of ammo and some good armor as eggs weigh a lot.
3) Fly into an area of the trench that doesn't have many wyverns in the area
4) Find preferred egg varient and level. To get wanted level and gender, eat bad eggs and kill low level adults or wrong gender adults but if you find a good wyvern, keep it alive so it can drop an egg.
5) Once you find a good egg and pick it up, leave immediately or kill wyverns because adults will aggro to you once you pick the egg up. If you play on Ragnarok, there's a tunnel in the direction of the ocean that wyverns can't fit through but pteranodons can and it leads out of the trench.
6) Put the egg next to a heat source for it to hatch.
7) While you wait for it to hatch, stock up on tranqs to knock out female wyverns to collect wyvern milk because that's all they eat until they're fully grown and for imprinting. Pack narcotics because wyvern torpor drains incredibly fast.
8) Once you have milk, refrigerate it and once the baby hatches, put milk in its inventory immediately so it won't starve.
9) Once it gets to the point it can be imprinted on, walk up to it and see what it wants so do out of be hand fed milk, cuddle, or walk. If you do that for a bit then it's imprinted.
10) Once it fully grows then it eats normal meat.
