I heard from a friend recently that in Gaiden, it was possible to kill off three of Alm's units, and then revive them on Celica's side using the revival spring at the dragon shrine. Apparently they stay in Celica's army if you do this. Hypothetically it would work with the Fear Mountain spring too. So if you wanted to send Clive to the temple of Mila, then give Nomah to the Deliverance, you could. I've tried googling this but I'm having a hard time finding results.
Has anyone tested this to see if it works in Shadows of Valentia? Is anyone inclined to?
