One of the major concerns that I've had with the Spiritualist class is the use of magic items on the Phantom. Specifically finding a way for the Phantom to keep its worn items between summons and when switching from Ectoplasmic manifestation to Incorporeal. I recently stumbled over the spell "Ghost Brand" from Ultimate Intrigue, which would seem to solve this issue. However, the references to "flesh" and "skin" in the spell's description make me uncertain of if using Ghost Brand to attach items to a Phantom would be a valid use.
So, can magic items be attached to a Phantom with Ghost Brand? If so, would they stick around between summons or manifestation switches?
