Mingle Magic
A Mystic theurge is capable of intervining his trades
A Mystic theurge can use an amount of spell slots equal to his intelligience/charisma modifier to prepare/cast spells of the other casting class. You may not use this on spells over the spell level limit. For example Joe a Cleric 2/Wizard 3/MT 4. Joe has an Int of 18. Thus Joe can use four cleric slots to prepare wizard spells or vice versa, but he cannot mingle spells of over lvl 2

Fuel to The Fire
A Mystic Theurge can burn up a spell slot of a level equal to the metamagic price from the other casting class to fuel the metamagic of the otheer casting class. The base spell level you can fuel with this is marked in the table as is the max bonus you can substitute by using slot.
For example you could cast a level 4 arcane spell with a +2 metamagic. Said spell would take a level 4 arcane slot and a level 2 divine slot.

Practiced Spellcaster
You gain the Practiced Spellcaster feat for both your arcane and divine casting.

Needs more class features, but here is what I have now. It basically ends with the same amount of casting as the standard theurge, but now you can have maybe an Arcane 18/Divine 16 and you get class features!

What do you mean by "equal to the metamagic price"? The spell slot increase? The new spell level?

Give them arcane casting in light armor, the major issue beyond lack of synergy.

Still not a power house, but I can see potential for Cha based arcane/Fixed Healer guy in some role other than a corpse.

[Frog Dragon]

I considered the light armor casting, but I don't think it's necessary. It's just something I don't think needs changing.
I hope Fuel for The Fire is clearer now.

What does "Class Ability" in the table refer to?

[Baron Corm]

What's the point in making a 15-level prestige class, other than tying it to the mystic theurge? Why not just make this a base class with both arcane and divine spellcasting?

Agreed, actually. Or even, perhaps, a series of feats.

A Prestige Class is, in my mind, something that describes who you are, not what you do. This seems to be very solidly a "what-I-do" sort of class: I cast both Arcane and Divine spells. To me, that means it would serve the game better as feats or as a base class.

For example:

Theurgic Practice
Prerequisites: Practiced Spellcaster, Ability to cast 2nd level spells from 2 different classes.
Benefit: When calculating your spells known and spells per day, treat your total caster level in each spellcasting class as the sum of all your caster levels in that class plus one half of your caster levels in all other casting classes. For example, a Cleric 4/Wizard 6 would cast spells as an 8th level Wizard (6+2) and a 7th level Cleric (4+3).

Theurgic Metamagic
Prerequisites: Practiced Spellcaster, Theurgic Practice, any 2 metamagic feats.
Benefit: Once per round, by sacrificing a spell slot from one of your caster classes, you may, as a free action, apply a metamagic feat you know to a spell you cast from one of your other classes without increasing the casting time. The spell sacrificed must be of a level equal to or higher than the level adjustment of the metamagic feat applied. For example, a Cleric 4/Wizard 6 could sacrifice bless, a 1st level Cleric spell, to turn her 3rd level Wizard spell fireball into an empowered fireball. The new spell would still use up a 3rd level spell slot.

It has to be a 15-level PrC so that it can tide a double-sided caster from 5 to 20 without losing another caster level on either side.

As for the "what you are not what you do" issue... Doing magic IS what you are. Mind you, it's also the reason that my MT fix was called Mage Priest (http://www.giantitp.com/forums/showthread.php?t=119067), and was tied to the Cleric class specifically. It also factored into why I later made a close to identical class for Favoured Soul/Sorcerers, the Chosen Sorcerer (http://www.giantitp.com/forums/showthread.php?t=119197).

I guess MT would make a better base class than a PrC, but we'd need to calculate a whole spell list and new spell progression and everything, or it would kick Wizard & Cleric's arses until 6th level and still give 5 Wizard/15 Broken Spellcasting PrC Combo a run for his money.

[DragoonWraith]

The alternative to the 15-level progression is a capstone that gives you dual progression on any level where you'd normally gain single progression. I did this with my Cerebremancer. My Cerebremancer also loses more spellcasting levels during its own progression, though (ending up -2/-6 if you take full-progression after the capstone, which is still quite better than -3/-7 of normal theurges).
