I was following the Mystic Theurge thread in the general forum over the last few days. Its basic conclusion was that the Theurge was a very weak prestige class at lower levels, and it only became balanced over level 10.
The primary reason for this was the prerequisite of casting Arcane and Divine 2nd-level spells. At sixth level, a Wiz3, Clr3 split is generally considered to be very underpowered.
This could be avoided if it was possible to enter the Theurge class at an earlier point, but if it only required one level of either arcane or divine spellcasting ability (say, 1st-level spells only), the Theurge would be too good. I don't like the idea of a Wiz9, Clr1, MT10.
So, with minimal changes to the class, here's an idea to allow earlier entry to the Mystic Theurge, but still requiring an investment in both arcane and divine spellcasting levels:
MYSTIC THEURGE
Requirements:
To qualify to become a mystic theurge, a character must fulfill all the following criteria.
Skills: Knowledge (arcana) 5 ranks, Knowledge (religion) 5 ranks.
Spells: Able to cast 1st-level divine spells and 1st-level arcane spells.
Special: The mystic theurge must maintain both a mastery over and a balance between divine and arcane energies at all times. For each matched pair of non-theurge divine and arcane spellcasting classes (e.g., wizard 1/cleric 1 or wizard 3/cleric 3), a character may take a pair of theurge levels.
For example: Jozilee aspires to be a Mystic Theurge. She takes a level in wizard and cleric (a matched pair), and then two levels in mystic theurge. Jozilee is now a 4th-level character (Wiz1, Clr1, MT2) who casts as a Wiz3, Clr3. Before she can take more theurge levels, she must have another matched pair of wizard and cleric levels. Which means Jozilee can not advance as a theurge again until 7th level, when she could (if desired) become a Wiz2, Clr2, MT3.
Using this progression, dual divine and arcane spellcasting ability is gained slightly faster at the earlier levels (at level 7 you can cast 3rd-level spells vs. 2nd-level spells per the core rules). But it is delayed at the later levels: you cannot get the last two levels of theurge until character levels 19 and 20.
Also, you can not get 9th level spells if you take all 10 levels of theurge (disclaimer: I'm not considering epic levels here). So no Wiz7, Clr3, MT10 with 9th level wizard spells and 8th level cleric. If you want ninth level spells, you can't take more than six levels of theurge (Wiz11, Clr3, MT6).
