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

To the person who asked, Phoenixes eat Sulfur.

If you trap it put down a lot of sleeping bags. If you die and can't respawn right next to it, and you respawn outside of render distance, it'll get out of the cage and fly away.

aparrently putting something to sleep and feeding it its favorite food is considered violent but setting a bird ON FRICKIN FIRE isnt wow wildcard

Easy, Wait till the heatwave is over then when ashes are down build a cage 5 walls up over the. Itll spawn and be trapepd, Then use oil jards. The more you use the faster it tames.

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

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

If u want to spawn the phoenix by command:
admincheat summon Phoenix_Character_BP_C
