Spoiler troy fight something odd

I found something odd with this fight i was dieing left and right on this boss tring to get how to get around every thing .Thin i found if u just stay in the little hall where u fall down in the fight becomes super easy .

The odd part is if u stand in the hall he jumps over once thin warps back to the mid of the arena does 2 rounds of orbs thin jumps over and the orbs that he shoots out after jumping all hit the wall and pop right away and resets exa exa .
All most seem like the game see hims as out of bounds and makes this crazy fight go from super hard to easy

theres another method which is a bit of a cheese, whereby if you’re near the edge, he flies past goes into water and insta-dies
