Making a levelled scrolls component

[Bardez]

I'm looking at introducing levelled scrolls for Caster Crafting.

My thought process is to read through my registry of spells, and if they have multiple abilities† to loop through them and if the level isn't `1` to create new scrolls for each ability with a level > the minimum caster level necessary to cast the spell. So the dynamics that came immediately to mind were: "what about Spell50?" I'm curious what other gotchas exist that this group can think of.

†: things like spontaneous casting and Olvyn (I think) add new ability headers to spells that I'd need to ignore. These abilities are only tangents to the original spell, so I'd have to ignore spell headers that aren't matching the first spell's opcodes or something similar.
