I would take a pair of diamond boots that would teleport you to a mystical cave where a phoenix  lay.

I would craft a pair of the finest fire proof gloves that are made of piranha fish scales to tame the untamed. 

I would take a star wand to defeat the undefeated by freezing them like ice.

I would bring a mysterious map that shoots a laser beam to the destination.

I would take a flash camera to blind the phantom phoenix then I can tame him.

I would take a cheese and ham sandwich, made with rotten flesh bread to distract the phantom phoenix.
