Ive Been Working On This For Quite A While, The Basis Of This Is Obito’s Ability To Phase Through Everything.
First I Made An Astral Bottle, And Then I Weaved The Duat Around It. Then I Expanded The Duat Around My Body, So Everything Astral That Comes In Contact With Me Phases Through. (Placed My Astral Body Within The Bottle Btw), And Voila. The Astral Ability To Phase Through Anything And Touch Whatever I Want Without Being Affected-
