Once they turn into ashes after the Heatwave ended and not tamed, mark the spot its ashes landed with something you can find easily. Now just toss down some oil jars around where the ashes fell. Throwing ten at the exact spot will destroy the oil. When oils were placed around the spot, light it up with any sort of weapon or a dino that can create fire; such as flame arrows, flamethrowers, pheonix and finally the FIRE WYVERN(Alpha will work too, but it won’t be easy). Once you light the oil on fire, they should disappear after some time, when they do disappear, replace the oil on the similar spots and light them up. Repeat this progress until tamed. Once tamed, they should be bugged out and won’t have any animations. To fix them just simply upload the pheonix to the Ark creature datas through a supply drop or an obelisk. Any colors or obelisks will work. After uploaded, just download the pheonix back. And there you go, you got yourself a pheonix. It should also take around 100-200 jars.
You can get it to spawn next to your base because of the following: It always respawns at it's last location, so if the heatwave ends while you are following it you will know where it is for the next heatwave. It also chases you when you eat flowers... hint hint
Find a phenix during a heatwave and follow it until it ends. The phenix will turn into ashes and land on the ground but will spawn right back at the same exact spot during the next heatwave. Build a trap 6 blocks high so I can't glitch out and you have yourself a trapped phenix to tame:)
Fun fact! You can tame the Phoenix by hitting it with a torch so you don’t have to waste you’re time shooting it and missing and what not just wanted to help everyone out because this creature is definitely something worth getting
It introduced a new taming method,while not the pseudo-boss we prayed 4 but to tame it u set it on fire with flame arrow,flame throweror a fire Wyvern,they only spawn during heat waves.keep this in mind.
