[Spell] True Permanency

[Jack_Simth]

The important component is the ShadowCraft Mage PrC from Races of Stone - turns any Illusion(Figment) spell the mechanics of a Shadow Evocation/Conjouration spell with some caveats - combine that, Silent Image, and Heighten Spell, and for a 9th level spell slot, on the material plane, you get an 80% real 8th level or lower evocation or conjouration Sor/Wiz spell.

There's ways to twink it out more; feats and PrC abilities that increase the reality of all your [Shadow] spells, casting it from the plane of Shadow, a nifty feat that gives you a free level of Heighten whenever you're standing on earth or stone, Easy Metamagic to reduce the cost when you Heighten a spell, et cetera. There's a particular build that can potentially give you a 140% real Miracle for a spontaneous conversion of an 8th level spell slot..... as a Wizard.

But for breaking this particular spell, all you need is a 9th level spell slot and a few levels from a particular PrC (you can just keep casting until your 80% chance succeeds on you.... or voluntarily fail your own Will save for the save you don't need to make in the first place and have it work on the first try... but that tends to give DM's headaches).

Edit: As for the link....

Edit 2: And to unbreak it for a build with that PrC, it would simply be a matter of changing the school to Universal - where the existing Permanency currenly resides.
