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!
I read a tip that these guys are amazing at doing wyvern trenches, and they are amazing at the fire trench, but my lv 287 was slaughtered in the lightning trench, so whatever you do don’t do the lightning trench with these guys.
Desmodus can be tamed with blood packs, it’s a passive tame, and you can give it smaller tames of yours to make its efficiency go higher for more levels.
The Desmodus can harvest spoiled meat in absurd amounts, the bigger the creature, the more spoiled meat you get, which is good for getting narcotics.
Desmodus can also harvest blood packs from creatures, without killing the creature. If you have 200 blood packs in the Desmoduses inventory, you can craft a sanguine elixir, which is good for taming, as it raises the taming bar by 30. It can also be used for imprinting + passive taming.
At night, you can use echolocation, which turns the Desmodus invisible, meaning you can easily steal Wyvern eggs, Drake eggs, etc.
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.
