Tips & Strategies

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
Steps to Tame a high level Desmodus with 100% Effektiveness (you need a low level Desmodus to start) :
Step 1: Tame a Stego/Andrewsarchus and saddle them (the saddle on the Andrew is essential!)
Step 2: Tame a Moschops of any level
Step 3: Farm 400-600 Bloodpacks
Step 4: After finding your target Desmodus take out your Stego/Andrewsarchus and your Moschops
Step 5: Put all the Bloodpacks except for the last 100 in the Moschops (the other 100 you keep in your own inventory)
Step 6: put the Moschops on "Following: Lowest" and let it follow your Andrew/Stego
Step 7: Aggro the Desmodus by approaching it and let it grab the moschops, the Desmodus will eat 10 Bloodpacks from the Moschops' inventory and then drop it, this will raise its Effectiveness by 1-3% (repeat this until the Desmodus is at 100% Effectivness. Do not unmount while doing this!)
Step 8: once the Desmodus is at 100% Effectiveness unmount and offer yourself up to the Desmodus. It will grab you and eat 10 Bloodpacks and then drop you.
Step 9: after it dropped you immediately mount your Andrew/Stego again. And let it grab the Moschops again so it's Effectiveness goes back up to 100%
Step 10: Repeat Step 8 & 9 until the Desmodus is tamed.
This will allow you to get perfect tames.
Babies CAN EAT MEAT as a baby to raise them.
Easy taming :
1) Use med brew to heal yourself while you extract blood packs with a blood extraction syringe. About 100 is fine.
2) Agro bats and run away. Wait until a lower level one gets left alone.
3) Get your best armour and clear the area. Put blood packs in your last slot and let the bat pick you. Don't struggle, just stay still.
4) After taming, use it to gather blood packs. Then tame a Higher level bat.
In Fjordur the spawn locations are :
Latitude:38 Longitude:75, inside a cave under a waterfall
Latitude: 90 Longitude: 78, cave as well
Latitude: 50 Longitude: 14, cave
Use a Daedon, put meat inside, set to passive, passive healing on and kill all the other desmodus until there is only one, then duck under the Daedon and the desmodus will grab it, suck it's blood and the effectiveness will go up 3-4%, don't leave the area, hide and wait until 100%. Once 100% effectiveness, let it grab you (make sure you have 150-200 blood packs) and you'll tame it. Use cryopods if possible to bring back the Daedon.
They can't dismount you from an Andrewsarchus saddle sit safely within the cockpit and pick off the bats you don't want
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!
As others have stated. It takes a gd year to hit 100%. Your better off quantity over quality when looking for good states. Treat em like deins. Eventually you'll get decent stats. Honestly. Just quick tame all high levels and combine em when you get high rolls.
A 150 gets about .5% effectiveness each time it grabs the moschops. So it takes 100 times of it picking it up to get up to 100% effectiveness
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.
you can use this to tame bloodstalkers
Babies take bloodpacks as food when raising.
