may Take-10; automatic success with read magic or if owner of spellbook is on hand to helpSuccess:  No need to decipher this particular script again; identifies and gives general idea of spell's effects; if a previously learned spell, can be used to attempt preparation; if a new spell, can be used to learnRetry:  Allowed once per dayPREPARING SPELLS FROM FOREIGN SPELLBOOKSPrerequisites:  Deciphered spell that previously has been learned, minimum caster level to cast spellTime:  10 minutes per spell level (5 minutes for a level-0 spell; total preparation time still takes at least the normal 15 minutes per 25% spells prepared)Spellcraft check:  DC 15 + spell level; may Take-10Success:  Can cast normally, but must repeat check every time spell is prepared from borrowed spellbookRetry:  Allowed once per dayLEARNING SPELLS FROM FOREIGN SPELLBOOKSPrerequisites:  Deciphered spell, minimum caster level to cast spellTime:  2 days per spell level (1 day for a level-0 spell)Cost:  By spell level<ul> <li data-xf-list-type="ul">0: 12gp</li> <li data-xf-list-type="ul">1: 25gp</li> <li data-xf-list-type="ul">2: 150gp</li> <li data-xf-list-type="ul">3: 375gp</li> <li data-xf-list-type="ul">4: 700gp</li> <li data-xf-list-type="ul">5: 1125gp</li> <li data-xf-list-type="ul">6: 1650gp</li> <li data-xf-list-type="ul">7: 2275gp</li> <li data-xf-list-type="ul">8: 3000gp</li> <li data-xf-list-type="ul">9: 3825gp</li> </ul>Spellcraft check: DC 15 + (2 * spell level), no Take-10 allowed; stackable circumstance modifiers:<ul> <li data-xf-list-type="ul">+2 for access to a library with suitable spell-relevant material</li> <li data-xf-list-type="ul">+2 if a colleague working together on the same spell beats a DC 10 (regardless of success) OR a wizard who knows the spell tutors you during 1/2 the time you spend researching (Note that the colleague and tutor bonuses do NOT stack with each other)</li> <li data-xf-list-type="ul">+2 for spending twice the time (i.e. 4 days per spell level)</li> <li data-xf-list-type="ul">-1 per day of interruption</li> </ul>Success:  Spell learned, prepared, and ready to scribeRetry:  Allowed when another rank in Spellcraft is gainedSCRIBING SPELLSPrerequisites:  Prepared spell, materials (spellbook, inks, etc).Time:  1 day + 1 day per spell level (1 day for level-0 spells); 1/2 time if transcribing from own spellbookCost:  10 gp per spell level (5 gp for a level-0 spell)Notes:  1) A spell may only be prepared from a foreign spellbook if it previously has been learned.  2) A lost spellbook may be reconstructed by scribing prepared spells.  These spells may have been prepared before the loss, or may be prepared using a foreign spellbook.  3) With each new level gained, a wizard is assumed to have learned 2 new spells of any level he can cast.  These require no time, cost, or check for learning, but DO require the time and cost for scribing.  Spell choice is subject to DM approval and will generally be restricted to spells that are very common and/or that the wizard has previously researched or had exposure to (e.g. in a library or by conferring with another wizard who knows the spell).</blockquote>
