Wizard Spells and Borrowed Spellbooks
A
wizard can use a borrowed spellbook to prepare a spell she already knows and has recorded in her own spellbook, but preparation success is not assured. First, the wizard must decipher the writing in the book (see
Arcane Magical Writings, above). Once a spell from another spellcaster’s book is deciphered, the reader must make a
Spellcraft check (DC 15 + spell’s level) to prepare the spell. If the check succeeds, the wizard can prepare the spell. She must repeat the check to prepare the spell again, no matter how many times she has prepared it before. If the check fails, she cannot try to prepare the spell from the same source again until the next day. (However, as explained above, she does not need to repeat a check to decipher the writing.)
Adding Spells to a Wizard’s Spellbook
Wizards can add new spells to their spellbooks through several methods. If a wizard has chosen to specialize in a school of magic, she can learn spells only from schools whose spells she can cast.
Spells Gained at a New Level
Wizards perform a certain amount of spell research between adventures. Each time a character attains a new wizard level, she gains two spells of her choice to add to her spellbook. The two free spells must be of spell levels she can cast. If she has chosen to specialize in a school of magic, one of the two free spells must be from her specialty school.
Spells Copied from Another’s Spellbook or a Scroll
A
wizard can also add a spell to her book whenever she encounters one on a magic scroll or in another wizard’s spellbook. No matter what the spell’s source, the wizard must first decipher the magical writing (see
Arcane Magical Writings, above). Next, she must spend a day studying the spell. At the end of the day, she must make a
Spellcraft check (DC 15 + spell’s level). A wizard who has specialized in a school of spells gains a +2 bonus on the
Spellcraft check if the new spell is from her specialty school. She cannot, however, learn any spells from her prohibited schools. If the check succeeds, the wizard understands the spell and can copy it into her spellbook (see
Writing a New Spell into a Spellbook, below). The process leaves a spellbook that was copied from unharmed, but a spell successfully copied from a magic scroll disappears from the parchment.
If the check fails, the wizard cannot understand or copy the spell. She cannot attempt to learn or copy that spell again until she gains another rank in
Spellcraft. A spell that was being copied from a scroll does not vanish from the scroll.
In most cases, wizards charge a fee for the privilege of copying spells from their spellbooks. This fee is usually equal to the spell’s level × 50 gp.
Independent Research
A
wizard also can research a spell independently, duplicating an existing spell or creating an entirely new one.
