You forgot hatch boost
Anyone knows if you can revisit the worlds of legendaries after you catch them or if they vanish forever upon exiting?
As for the shiny chance, here's to clarify:
Legendaries/UBs have a 1/4096 chance to be shiny and the shininess is determined when the battle starts, so you can only soft-reset for nature and IVs. Non-legendaries/non-UBs are determined as shiny or not the moment you enter the area, so you can soft-reset and they will still be there for you to battle as shiny, so reset until you get one with the nature you want! They also have 1/4096 chance to be shiny though, so heads up.
