This one is easy. To tame it you just need to shoot it with a boa launcher in the tail so it can't fly, have it fall in a valley that it can't climb out of, bring it fish every day, and finally, touch it on the nose. It will be your lifelong friend after that, and it will let you fly on its back. Just don't trust it to save your leg in a fight with another dragon. You will literally lose a leg and will have to learn the peg leg engram(not real, but should be!).
Don't spawn in a bunch if you have admin commands, our entire tek base got covered in dragons so we had to kill them all and since we Insta killed them their bodies exploded (glitch exploded) and all you could see from one side of the island to the other was thousands of stretched dragon bodies. We had many people come to the admin store with questions that day. Worst part was that I was currently on my shift at the admin store at the time, so I had to answer the questions. Long story short: they hella big so don't go spawning in an army.
