Reality is malleable. Nothing is impossible.
When you cast this spell, whatever target, effect, or area you affect immediately gains the impossible status, even if this spell fails to have any effect on the target, effect, or area in question. If your target already has the impossible status, this spell automatically fails (at no XP cost). You cannot use this spell to remove the impossible status from any target. This spell itself - and each casting of it - is considered to have the impossible status, and thus you cannot alter it in any way with a casting of this spell or similar effects.
By casting this spell, you can alter reality in any way you see fit, be it altering a creature in some fashion, creating an item from nothing, totally changing the local terrain, or performing some other normally-impossible feat. Regardless of how you choose to alter reality, all elements involved gain the impossible status; if any one affected element already has such status, the spell fails (at no XP cost).
In regards to creatures, you can cause a status of your choice to permanently affect the creature (such as haste, slow, petrification, or reraise, keeping in mind that this is not an exhaustive list). Such a status affects the creature until it would either end (such as with reraise) or is ended by removing the impossible status from the target. A status put on a creature by virtue of wish can only end by the status' own natural course or by an effect that can remove the impossible status.
In regards to items, you can spontaneously create an item of any sort, so long as it is an item that can be created through Magic (that is, if the item you wish to create is a normal item, or a Magic-aligned item, you can create it). Such an item has the impossible status upon its creation. Alternatively, you can alter an existing item in any way you see fit, either by adding or removing abilities from it. You can attempt to alter Magic-aligned artifacts in this manner, though doing so increases the chance of this spell failing.
Effectively, this spell is essentially a much more free-form version of standard d20 wish. Any effect that that spell can produce, this spell can produce up to double such an effect with minimal chance of failure.
If you use this spell to attempt to perform a particularly impossible task, it may fail. The chance of failure is at the DM's purview. You may choose to accept the impossible status upon yourself in exchange for a single casting of wish, no matter how egregious, to succeed. If you do so, you gain the impossible status as part of casting the spell (and as such you cannot affect yourself with such a casting), and the total XP cost of casting this spell is tripled.
Due to the nature of this spell, nothing can make a saving throw against any effect it produces: you are essentially rewriting reality to your whim, which cannot be overcome simply by physical endurance or force of will. However, if you affect anything that has Spell Resistance, you must overcome that in order to affect such a target with this spell, as SR represents an inherent resistance to such rewritings of reality.
XP Cost
Casting this spell costs 5,000 XP.
If you create an item, you must pay additional XP equal to double the XP normally required to make the item. If you modify an existing item, you must pay additional XP equal to the XP normally required to modify the item.
If you attempt to alter an artifact, you must pay an additional 15,000 XP.
