Mystic Demiurge (3.5e Prestige Class)

Mystic Demiurge
"It's hard to imagine but all things, men, rocks, the sea and sky... are composed of the same base particles. Magic is no different, we may not know it but there is a single common source of it all, and I intend to find it."

The mystic theurge takes the power of both arcane and divine magic and focuses on both of them, to the sacrifice of all else. However, only with age and experience does one manage how to truely master both and realize they are one in the same. The mystic demiurge has broken down the basics of both types of magic and found their fundemental abilities, and with this knowledge they can reshape either path to their liking.

Becoming a Mystic Demiurge
Mystic Demiurges are a logical advancement to mystic theurges, and any dual-casting class which takes both arcane and divine magics under their steed.

Class Features
All of the following are class features of the Mystic Demiurge.

He does not, however, gain any other benefit a character of that class would have gained. This essentially means that he adds the level of mystic demiurge to the level of whatever other arcane spellcasting class and divine spellcasting class the character has, then determines spells per day and caster level accordingly. If a character had more than one arcane spellcasting class or more than one divine spellcasting class before he became a mystic demiurge, he must decide to which class he adds each level of mystic demiurge for the purpose of determining spells per day.

At 1st level a mystic demiurge can use the caster level of his arcane and divine classes to determine class level based effects which scale with level from his two spellcasting classes, up to their HD. For example, the wizard's familiar or a cleric's turning level can be advanced. It does not grant any other abilities not yet gained... a druid does not gain wildshape if he does not possess it first, nor any new animal shapes (though wildshape attempts per day increase), nor does a wizard gain bonus feats.

A mystic demiurge can prepare arcane spells in divine spell slots or vice versa. They remain their original type (arcane or divine). Domain spell slots cannot have non-domain spells in them, this ability only applies to normal spell slots.

If a mystic demiurge uses two different ability scores for each of his classes (such as wisdom and charisma for cleric and sorcerer casting) they may use whichever score is highest to determine spell DCs and bonus spells per day for both classes.

He may use the caster level of whichever spellcasting class is highest for both forms of spellcasting.

From this point on any spell he casts counts as either arcane or divine, whichever is most beneficial. This means, among other things, that they can avoid arcane spell failure in normally arcane spells, or power items and feats which consume arcane spells in normally divine spells, regardless of the original source the spell was drawn from.

Playing a Mystic Demiurge
Combat: The msytic demiurge is a pure caster, and focuses on little else. They have a slew of spell slots to use, and thus can endure a very long time.

Advancement: Any dual casting classes are good for the mystic demiurge, but those who obtain combined caster levels may be able to take a single spellcasting advancing class and not lose any power, once they have maxed out on additional spell slots gained by their classes.

Resources: Mystic demiurges can be found with either groups of their base casting classes, often wizard and cleric. Unless prejudice exists within the base groups, they usually are welcome with either.
