Tent no longer works. Thease are the best and one of the easiest to tame, breed, and to clean up rotten meat. It's pretty much a walking refrigerator and great for defense (personal). They can definitely make a difference in Pvp when starting out. Tho they don't exactly have speed, they can give and take alot of dmg if bred right. In my opinion it's as much as a must have tame as a Rex or any flying mount. Just watch out for large groups, and what's around you when taming. (Gaining Agro from other creatures means your more likely to get attacked). And make sure you don't kill anything close to what your trying to tame. Other then that. A good few chunks of Rotten Meat and your on your way.
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
