Doesn't the fact that resting is more frequent in BG3 actually devalue scrolls? Like, if I can restore spell slots after every fight, then why would my wizard ever use a scroll?
I'd be fine if everyone could use scrolls, but it required a successful (DC 12 or 15 + spell level) Arcana check to use a spell you don't have on your list. This would provide some combat reasons for a Barbarian/Monk to take Arcana as a proficiency. The spell is already cast into the scroll, after all. You don't need magic to cast it, just the ability to read it.
I doubt whether a double roll is a good idea.
I did a quick test using a scroll of fire bolt and a helmet giving 18 int.
I ordered Lae'zel to use the scroll. When she was wearing a helmet, her chance of hitting was 50%, but when she took it off, the chance decreased to 30%.
Seems the scrolls are still using the stats so most will be competently non-profitable on characters with low intelligence (I think the rest of the scrolls work the same, but I haven't tested it)
