One thing that I didn’t like about the Elders Scrolls universe was that there were really no true clerics. Just mages that knew restoration magic and no gods needed. D&D made clerics and those devoted to a divine, etc feel unique in the world. Apparently 5e is moving away from this somewhat (power doesn’t come from a god, but from within some how as explained in to me in another post). With this homebrew, it feels even more so…
Mods fix that.
But there are priests, and only magical capable individuals can use the restoration magics. Most of your common, average people cannot really use magic. Player character can because they're always special somehow(and mechanics reasons). Otherwise we couldn't have people dying of injuries and diseases.
There's also plenty of gods. Including Magnus, the source of all magic.
But anyway...
Allow wizards to use the scrolls, but not scribe them to their spellbook. It makes having a cleric in your group for buffs redundant. Scrolls are finite(you'll eventually run out and have to acquire more), making having a cleric in your group pretty advantageous. Having Gale able to cast them is just... ugh.
