Another update! Thanks to Curse Never Dying for explaining a simple item duplication glitch that solves the problem with limited Spider scrolls. It requires a follower, though, so I recommend Cicero since he could well be as crazy as the Spider. Ralis Sedarys, already on Solstheim and pretty clearly addled in the head, is also an option, but any follower could do (temporarily).
