Special Notes: While this class is using the name of Mystic Theurge, it is not exactly a copy of the MT class from official sourcebooks as it provides a wider range of possibilities. Any two spellcasting classes can qualify for and be scaled by this prestige class, not just one arcane and one divine. Furthermore, because of game engine limitations, only one spellcasting progression will gain spells known (which one is chosen based on a currently-untested priority list). Both progressions will gain spells per day, however, and taking a single level of the neglected class alone will give all missing spells known. The exception is the Wizard class, which always gains two spells on each levelup with spells known, irrespective of gaps in knowledge.
Blurring the line between divine and arcane, mystic theurges draw power from divine sources and musty tomes alike. While most spellcasters choose one path to magical power, mystic theurges walk two roads at once, simultaneously mastering spells common to clerics and wizards.

Spellcasting: When a new mystic theurge level is gained, the character also gains new spells per day and spells known as if they had also gained a level in the two casting classes they have chosen to progress when they took the first level of Mystic Theurge. They do not gain any other benefit a character of that class would have gained, such as bonus feats. If a character had more than two spellcasting class before they became a mystic theurge, they must decide to which two classes they want for the purpose of determining spells known and spells per day.
If one of the two classes is warlock, at level 10 the Mystic Theurge will acquire the Eldritch Adept feat, which qualifies for Eldritch Master.
To meet the spellcasting requirements for a prestige class, you must have met the spellcasting requirements by using only a base class.
In other words, a MT 10 / Wizard1 does not qualify for a PRC that requires 3rd level arcane spells. Even though this combination would grant access to much more than 3rd level spells, the game requires that you have spellcaster class level of Wizard 5 (in this case). It doesn't count prestige class access to spell progression like one would expect.
This class benefits from the PML spell scaling system.
