Raising one of these can be simple or very difficult depending on what your looking for. Normally players do 1 of the 4 ways you can tame large wyverns

1) Hatch em and feed it wyverns milk, not very effective if your looking for PvP stats, and can be very expensive if your trying to tame multiple wyverns

2) Simply trading with other players, very effective for PvP stats since you can choose what states you want but finding the right seller can be tricky, again tgis can be really expensive as some players... May ask for your pinpal account no joke

3) Only works if you have access to a large wyvern and a cloning station. You can simply clone an exact duplicate of any wyvern or tame in your possession. Not the fastest way to accumulate wyverns and it's by far the most expensive, but if the stats are nice well this might be what your looking for.

4) Snow owl exploit. Experts only, "breeding"... This is by far the best method to doubling your large wyverns and it's also the fastest and cheapest way possible. Let's say you have breed wyverns and hatched them. Now your stuck with 3 new born lightning wyverns and have no access to wyverns milk and they are going to starve to death, what do you do? Well it just so happens they can't die if there health never reaches zero. Well you simply need to heal them occasionally with a snow owl.

Say what you want

Is it worth keeping an eye on the health meter?

Yes it is, if you don't want them dead

Do you have to be there every second?

No, more like every hour depending on how much health they have, it can be every 2 hours and so fourth.

How much does it cost for this method?

Gas and Raw Meat

A little gas for your AC units and some raw meat for your owl. In other words absolutely nothing.

quick tip: PRESSING THE HEAL BUTTON AND THE DISMOUNT BUTTON AT THE SAME TIME WHILE RIDING AN OWL. YOUR OWL WILL START HIS HEALING SKILL AND YOU'LL DISMOUNT AT THE SAME TIME. A FREEBEE FOR THOSE OF YOU WITH THINGS TO DO. SOO BECAREFUL NOT TOO FREEZE YOUR SELF AND GOOD LUCK ARK FRIENDS!!!! HLAD TOO HELP
