Invisibility

Source invisibility

The invisible target can't be detected with detect magic or other spells that detect magic auras. The invisibility can't be penetrated, revealed, or dispelled by spells of 2nd level or lower (such as see invisibility or glitterdust), though true seeing and dust of appearance can reveal the invisible target's presence.

Augmented (3rd): If you expend two uses of mythic power, the invisible target is undetectable by blindsense, blindsight, scent, and tremorsense.
