Two Addenda to "Spell Components and Item Crafting"

Two small things I should have mentioned in my previous post, except that I didn't think of them until later:

Spellbooks and Unique Spells: In addition to providing a source of Lore, some captured spellbooks may also contain the details of variant ("Level Up") or unique spells (which, in D&D, I would consider to be any spell not in the PHB). These spells may be learned the same as any other, using Lore, but should probably either be more powerful than other spells of their level (as befits their unique status) or have a slightly lower Lore cost.

That said, to ease book-keeping I'd argue that the option to buy them should be exercised at the next available opportunity or be lost.

Identifying Magic Items: Identifying a magic item becomes an exercise in expending Lore while examining the item. This returns some utility to the identify spell, in that casting this spell allows identification without Lore. Additionally, taking the item to a sage allows them to expend Lore on the character's behalf.
