You can easily navigate most of the caves on The Island with a Desmodus. Beware of Purlovia in the Snow cave as there are sections where you have to fly low and the Purlovia can stun and dismount you. Go at night and use the invisibility buff. There is no other way that I will do the Lava Cave than on one of these. They absolutely shred Onycs, just fly backwards biting and watch the flying rats melt.
This is one of the best tames in all of ark! It is the only flyer that can go in caves it has night vision it can go invisible and it has echolocation. It can get blood packs very easily. And it is the only way to craft sanguine elixer which can give an automatic 30% to either taming or imprinting ( note it can only be used once per imprint/tame) it also has a life steal effect and you can shoot while riding. It is also fast and has a dive ability kind of like the snow owl it can land on walls and roofs and also it has decent health and melee. Definitely worth the tame!
