Use a fire wyvern's breath to tame. Wyverns are faster than pheonixes but have a larger turning radius. The trap where you follow it and put a box around it is still a really good idea though.

Nooblets is the best YouTube channel he makes such easy was to tame the hardest tames so check it out he will blow your mind.

Food

It's diet consists of Sulfur

If you tamed one put metal or meat into it and it’ll cook/smelt it for you

3 spawn each heat. 5-6 wall high trap.

Highly suggest a trap it took 2 super heats on official x1 rates to tame on top stat fire wyverns while alternating turns with 1 other tribe mate and yes it was a low level

Take 1 Giga, 3 Argies, and a Phoenix for meat runs. Put all birds on follow (player, not Giga, so if you get stuck, stand up in the saddle and they'll fly above you). Argies get black-boxed with raw meat, and all the Prime Meat goes in the Phoenix. By the time you fill the Argies and go back to base, you'll have tons of cooked Prime Meat for recipes and jerky.

Get a tapejara and a tribesmember. One of you ride on the back of the saddle, the other drive. The person on the back should have either a crossbow and flame arrows or a flamethrower, if you're feeling daring. Fly near one and eat a rare flower. The phoenix will chase you, so you can fly away and the person on the back shoots the phoenix. Make sure you have ghille and cactus broth, because they only spawn in heat waves. If you are on a server where you can transfer dinos, you can build a metal box with an open side on the back of a quetzal, let the phoenix fly in, and wall up the opening. Proceed to light it up...literally. If you follow the phoenix during a heat wave, when it deepens know that next heatwave it will spawn in the same place. Build a large platform out of any material under where the phoenix will spawn. Wait for a heatwave, then quickly bola the phoenix and box it in. You can either build a big box and go in with it, or make a window you can shoot it through. Good luck!

YOU CANNOT PILLAR WHERE ITS ASHES ARE. Use this to help pinpoint its location when building trap.

Sometimes it will glitch and spawn on top of your trap ceiling. Try placing two layers of ceiling 6 blocks apart - it will spawn on first layer and be trapped.

Is it possible to spawn the Phoenix?if so please someone tell me the code because I can’t get scorched earth!

Darn thing caught me on fire when it spawned in. I was standing on the Nooblets trap. I climbed back up and it was out of the trap. I followed it on a wyvrn and when it turned to ashes, I couldn’t find it with a parasaur. I guess it despawned. I am sad.

If you're like me and still play ASE, use a parasaur's special to ping the Phoenix underground during a heatwave or after it. When you've found it... Build a trap and look at another tip I'm just quoting raasclark-Macncheezl

When heat wave start and Phoenix is back after it was ash pile use tons of oil jars and light them boom you have a Phoenix and they eat sulfur

The Phoenix is found on Scorched Earth during a scorch wave. After the wave is over, the Phoenix will turn into an ash pile and fall to the ground from where it was last hovering. The ash pile is not visible. Use a Tek Parasaur to detect exactly where it is and build a trap over it. It will come out during the next scorch wave. Flame it to tame it.

Did you know that the phoenix is the rarest creature in the game?

The Phoenixes eat sulfur once tamed.

You can use a fire wyvern to tame it

If you have a quetz, you can make a quetz catcher on it and use that to catch the Phoenix, allowing you to get close enough to flame thrower it.

Easyest way to tame it is to get a fire wyvern and use its fire breath to attack it and it will tame very fast depending on the leval of the phoenix
