Help creating a new spell!

[Lucius Foxhound]

In our last campaign, my illusionist Wizard was forced to fight his illusionist mentor. We both had True Seeing up, which made me really appreciate that spell! Basically, no illusion spell had any effect ... not Phantasmal Killer, not Mirror Image, not really even Shadow Evocation ...

So my character is working on a spell that improves illusions to right True Seeing. This is only a rough draft ... please help me with it!


True Illusion

Illusion (Shadow)
Level: Wiz/Sor 5
Components: V, S
Casting Time: 1 action
Range: Personal
Duration: 1 hour/level
Saving Throw: See below
Spell Resistance: Yes (harmless)

The character reaches into the realm of shadow when creating illusions, making them more realistic. While True Illusion is active, spells from the illusion school cast by the character receive a +2 to the save DC. In addition, those affected by True Seeing must succeed at a will save to see through the character's illusions. However, if this save is failed, those affected still receive any save or saves the illusion spell allows.

If it gets past true seeing, it should be higher level than true seeing. That would make it 7th level at a minimum.

Why must it be higher?

Protection from Evil (1st Level) protects against dominiate person and magic jar (5th level). Faerie Fire (1st) stops invisbility (2nd). Nondetection (3rd) protects against Scrying (5th).

Heck, even True Seeing (6th) protects against Weird (9th).

You answered your own question. (Handy hint: notice how the defender's spells are all lower level.)

To make something that misleads True Seeing, I'd agree that it has to be higher than True Seeing.

As Hong stated, the defending spell is lower, so True Illusion has to be higher than True Seeing.

Either 7th or 8th.

I'd add Glamer with the shadow as glamer will make people more susceptible to the Illusion.

From the srd:
Glamer: A glamer spell changes a subject's sensory qualities, making it look, feel, taste, smell, or sound like something else, or even seem to disappear.

OR
change it to just Pattern

From the srd:
Pattern: Like a figment, a pattern spell creates an image that others can see, but a pattern also affects the minds of those who see it or are caught in it. All patterns are mind-affecting spells.

Then the True Illusion is basically targetting the mind.
You might as well make it something akin to the Conjurer's Maze.

So maybe call it the Illusionist's Web
During the time the target is occupied, he is susceptible to physical attacks. All mental attacks fail cause he's too focused on his imaginary world.
I's say he would be equivalent of being flat footed while being the subject of said spell.

Cool idea, Lucius...

Let me know if you're interested in the Shadow Adept prestige class...
