Researching New Spells

Researching Spells
Creating a new spell requires research, money, time, and most important of all, skill.

It requires a minimum of one week per level of the spell plus one. At the end of each week of study, and research, you must succeed on a Spellcraft check. The DC of this check is given in the following table:

Table: Spell Level vs Spellcraft DC
If you fail the check, your spell research is not damaged unless you fail it by ten or more, in which case not only does the current week not count, but you have lost an additional week's worth of work.

At the end of each week, pass or fail, you must expend experience points and gold equal to 1/(Spell Level +1) of the total price of the spell.

The cost of the spell is 100 * minimum caster level * spell level. Level 0 spells count as 0.5.

Bonuses
To get the following bonuses, the source must be present for at least 3/4ths of the creation time of the spell. These bonuses are untyped and can stack with each other with limitations. You may use a total of up to two casters and only one library.
 * Aid of caster who would be able to cast the finished spell +1
 * Aid of caster who specializes in the chosen school of magic +3
 * Small magical library +1
 * Adequate magical library +2
 * Huge magical library +4
