Shadowcraft mage saves/etc?

[darqueseid]

These may be easy questions for somone whos played a shadowcraft mage before, but:

How do the save DC's for Quasi Real spells work? 
For example:
if I use a 4th level figment to mimic the 3rd level spell "fireball"
does it use the save DC for the whole spelll as 4th level? 
say the save dc for a 4th level spell of my level is 21,
The creature would get two saves:
first a will save, at dc 21:
Failing that, he would then get a reflex save for half damage, at what DC? 21? or would it be fo a 3rd level spell, 20?
Even if he succeeded on the will save he takes 40% damage, does he get a reflex save for half of that? at DC 21?

Additionally, lets say your Illusions DC is boosted to that 21 by 2 from feats affecting only illusion spells, etc, does the quasi- real fireball's reflex save use the illusions' boosted save DC or would it drop 2 DC to be equal to a normal fireball you would cast?

Also, Let's say your caster level for illusions is boosted by 1 and your 9th level(early entry ftw), does the quasi-real fireball do 10d6 damage on a failed will save or 9?

This is something I'd like to know, too...

Shadow Illusion says, "The altered spell functions identically to the shadow conjuration or shadow evocation spell."

Shadow Conjuration says, "...the save DC is set according to shadow conjuration’s level (4th) rather than the spell’s normal level." and Shadow Evocation has a similar line.  The save DC would be set according to the level of the illusion spell used and not the level of the spell being mimicked.

In the example you gave, you're not casting Fireball, you're casting a Heightened Silent Image and replacing the normal effect with the effect of Fireball.  You're still casting an Illusion spell, so feats like Spell Focus: Illusion still apply.
