Learning new spells from captured spellbooks

It's probably useful if I outline the procedure for learning new spells from other wizards' spellbooks. We've looked, previously, at the parameters around using scrolls, which are effectively a one-time-use means for supplementing a wizard's spell slots. Spellbook writings are permanent, though the rules for copying them are similar.

• In possession of an unfamiliar spellbook, a wizard must use read magic to decipher its contents. Read magic allows the wizard to read two pages per caster level; an individual spell consumes one page per level of the spell. (In the previous post I assumed that Riwyn was willing to expend the necessary number of castings, two, to read the full volume.)

• Once the spellbook's writings have been deciphered, the wizard can attempt to copy any number of its spells into his or her own spellbook, using his or her own personal notations. Each spell requires a successful Chance to Learn Spell roll, with failure indicating that the spell cannot be learned at the present time. A new roll can be attempted (assuming that the wizard still has access to the spell) upon attaining a new level.

• If the Chance to Learn Spell roll succeeds, the wizard must spend one full day of study per level of the spell copying the runes. (The degree of dedication required for this work typically can't be achieved while adventuring.)

Note that a wizard isn't able to memorize spells directly from a foreign spellbook, only from the wizard's own spellbook.
