Warrior Mage (Gish) build for Shadow Caster?

[Shin Okada]

Is it possible to make a Warrior Mage (Gish) build using Shadow Caster (Tome of Magic)?

Shadowsmith prestige class is a kind or warrir/mystery caster, but not based on Shadow Caster class and can use only 3 mysteries at best.

At this moment, the only "Gish" prestige class I could find for a multi-classed Shadow Caster is Dragonslayer (Draconomicon). It has full-BAB, but only 1/2 casting progression.

Is there any other good prestige class which a Shadow Caster can qualify for?

How about Eldritch Knight? D6, full BAB, but do lose one casting level.

I'm assuming you are able to substitute mysteries for spells in the pre-reqs as you were going to advance your mysteries with the Dragon Slayer Prc. EK does require you know how use all martial weapons, which is a pain, but you could do the 1 lvl dip in Dragon Slayer to get the martial weapons. Or you could do one level of Duskblade to the get the martial weapons and 2+ extra True Strikes never hurt.

Other PrCs are Spellsword, Human Paragon, Elf Paragon, & Abjurant Champion.

Well, actually, according to Tome of Magic P.117, a mystery user can be benefited from "+1 level of existing spellcasting class" or "+1 level of existing casting class". And a shadowcaster qualify a character for prestige classes if the requirement does not specify type (arcane or divine).

In case of Dragonslayer prestige class, that class does not require spellcasting ability at all. So, say, a multi-classed Shadowcaster, or even a single-class Shadowcaster can qualify for it.

I can always twist an existing prestige class or create a new one. But before doing this, I want to know if there are more gish prestige classes which a Shadowcaster can enter, without tweaking some rules.
