GUYS THATS IMPORTANT UP PLEASE!!!! You can STEAL WYVERN eggs using the invisibility ability at night up please that's an important tip!

You should tame a low level first get tons of blood packs then tame a high level

Blood extraction syringe + snow owl = easy blood packs to tame your first desmodus

I haven’t seen anyone mention anything about babies but they eat raw meat they won’t drink blood the blood packs. Hope this helps

Use tames that is carry-able by the desmodus that's on wonder and passive and get the desmodus to pick it up several times and this will increase taming effectiveness .

Make sure to have parachutes because they fly up when taming and will drop you.

Babies take bloodpacks as food when raising.

Feed these boys moschops do get up their taming effectiveness

You can extract blood in a tek sleeping pod. It works pretty well since you don’t have to eat from the healing. It’s end game af but if you got it and you want a bat or blood stalker you can have hundreds of blood packs in minutes.
