I lived in the ragnorok desert. One day I logged on and realized I got raided. All my tames, buildings, supplies, tribemates were gone. I was the only one who survived the raid and had spoiled meat on me. A level 145 vulture landed right next to me and I decided to just tame it. I now have 10 level 200+ vultures and they are invincible! I haven't been raided since, maybe people are scared of my vicious vultures or I just found a good base set up.
How to tame: put spoiled meat in last slot. Walk up to one on the ground and feed it. Wait till it lands again and keep feeding it.
These are easy without a tent. I've tamed a few dozen on Ragnarok at Viking Bay. Feed them and track it; they don't seem to wander to far. I've gotten to where I can track four at a time.
I just remove everything from my inventory except the spoiled meat and start feeding and running after them. If you time it right you can feed them before they land/take off and run to another one. They touch down twice before landing and leave a cloud of dust every take-off/landing.
Also, they can get into a regular doorway pretty easily. I learned that the hard way running for my life.
Vultures are the best against raider my base was getting raided omve the attackers got in my sun blocking flock of 57 vutures killed not only the raiders but there rex and two argys had the laugh of my life
