From MM6 Wiki
- what Rep/St in "ID/Rep/St" means? (in scroll table it was just 'identify')
- how does ID/Rep/St number correlate with identify item skill?
- does ID/Rep/St really depend on the book tier only, ignoring the scroll tier?
"ID/Rep/St" is the skill required to identify or repair an item. For scrolls/books, I believe what matters is just which spell it is. -user
