[SPOILER ALERT for newer players]
When I'm traveling with Ceres-Possessed Galiene, I keep having her waste my revive potions on her ghost swords. I get why you'd want your allies to be able to use your revive potions, so they can revive you if you go down. But, would it be possible to make an exception for the swords specifically? I don't want to have to have to never carry around revive potions just because she'll waste them all.
