Nonexistence

You make yourself completely undetectable to all creatures. This power has the following effects.

First, you are invisible and inaudible to all creatures. They cannot even detect your presence by means of blindsense, blindsight, scent, or tremorsense. They cannot pinpoint your location by any means.

Second, creatures remains unaware of your actions, provided you do not make any attacks or cause any obvious or directly threatening changes in the environment. If you attack, the effect ends.

Third, you are completely veiled from any magical, psionic or other means that might detect your location or existence. Only a deity, demon lord, or other such power can detect your existence.

If you take an action that creates a sustained and obvious change in the environment—for example, attacking a creature or moving a large or attended object that can be seen—the spell ends.
