Watch Nooblet best way to trap a Phoenix and he uses oil jars and a parasajr to find the ashes and traps it.

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

Its quicker to tame with a fire wyvrm, after feed it sulfur cusit doesn't easy anything else.. also you don't actually need a parasaur unless you're trapping it..you can actually ping it from the dino finder

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

here is two ways to tame this bub

one: the quick way,

1: heat wave

2: get on fast and good tame

3: find one

4: if found use fire wyvern or flame arrows

two: the trap way,

1: start from step 3 on way one but wait for heat wave to end.

2: find big pile of ashes

3: place a trap. add oil jars for good results

4: wait for next heat wave

5: light the fire bird up!

To the person who asked, Phoenixes eat Sulfur.

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:)

You can use the new bobs tall tales gene scanner to find it with no heatwave going. I have found 3 on the map at one time with this. Once you found the spot using the gene scanner use a cryo to lock on to it to find its exact location underground.

You can look for it with a parasaur when heatwave isn active...it can detect an ash pile...i got lucky and found one after 5min
