DESCRIPTION
You make yourself completely undetectable to the subject by erasing all awareness of your presence from its mind. This power has the following effects.
First, you are invisible and inaudible to the creature. It cannot even detect your presence by means of blindsense, blindsight, scent, or tremorsense. It cannot pinpoint your location by any means.
Second, the subject remains unaware of your actions, provided you do not make any attacks or cause any obvious or directly threatening changes in the subject’s environment. If you attack the subject creature, the effect ends.
If you take an action that creates a sustained and obvious change in the subject’s environment—for example, attacking a creature aside from the subject or moving a large or attended object the subject can see—the subject immediately gains a new saving throw against the spell. An ally of the subject creature that is able to see or perceive you can use a move action to warn the subject and thereby grant it a new saving throw.

Augment
This spell may be augmented in one or both of the following ways.

If you spend 6 additional MP, you may cast this spell as an immediate action

For every 2 additional MP you spend, this spell can affect one additional creature.

If you spend 8 additional MP, this spell effects one creature per caster level

In addition, for every 2 MP spent on any of the above options, the spell’s save DC increases by 1.
