The Phoenix eats sulfur only sulfur and nothing but sulfur so just keeput that in mind after you tame one.

Only one wild Phoenix will spawn at a time per map.

It usually spawns near the red obolisk or the sand dunes or the Rocky mountains behind the red obolisk. 80% of the times it's their 15% of the time it's near the silicon pearl loop in the middle of the map 5% of the time near the corners of the map. Happy hunting.

After heat wave is over where the Phoenix went into ashes next it heat wave it’ll spawn there! -TBFlame
