So! Jumpers become a JRPG healer. I suppose it was bound to happen eventually. Though this is a little bit of a unfortunate world to be a priest in with some of the implications. Mostly because the Almighty/God stand in kind of hates humanity and was only stopped from killing them all by his daughter. So Jumpers basically going to join the Main character in killing NotSatan! to save the world. And afterwards I'm... not sure. Aside from delving into the dungeons post game. Maybe he'll travel the world and try to get people to worship the Goddess/Almighty's daughter more given she was kind of entirely neglected by humanity theologically before she's revealed in the late game plot. Though If that happens I wonder if that wouldn't just essentially be jumper creating Fantasy Christianity.

On other notes, MP miser is really good for a mage. Only needing to use half your mana on spells is useful as hell and I wonder if it could apply to non Dragon Quest magic. The Observatory is interesting might become relevant later but for now Jumpers gonna treat the sky castle staffed by angels sort of like his spaceship from star trek. Keep it out of the way for the most part because its not really relevant to day to day life. Maybe put it high above Koridai like the islands version of Skyloft. Give the people there some guardian angels.
