Temple of Ed 2.0

If Ed could use the materialize skill on consciousnesses... What would it do? Could making the consciousnesses something that can be touched be of any actual benefit?

'Yes, assuming some things are true' When a consciousness or soul left a body they would start to naturally decay. For a consciousness being like Ed, the matter was no different. His split-off parts would also start slowly dying.

If materializing the consciousness meant getting rid of this issue then Ed could create some sort of ghosts that listened to his commands. The issue was then if those ghosts would still be able to pass through objects or if they would need some sort of skill to facilitate this. Not only that but if they would still be able to float about or if they would have to resort to walking.
