I am a huge visual learner and these helped me with the fight. I had these bookmarked when they were posted and I never put them on here (I'm sorry!). Good resource to have for people to read up on the fight for Oryx (Credit to /u/Taux). There's obviously a little more to the fights than these diagrams but it's pretty much all you need to know. Take note of numbering the platforms- some pick up groups call platform 4 & 3 "front left" and "front right." There's no mention of the blight bombs, stealing the knight's essence etc.
Preparation.
Phase 1- Starting the fight.
Phase 2- Platforms & Damaging Oryx
Phase 3- Running from explosions.
Phase 4- Arena Bubble & teleporting.
There's no map for the daughter's of oryx encounter but there is a blank map above. I will number it accordingly if you guys want to have me make a map for that fight so you know where to go for burn phases.
Hope these help!
