The creature or object touched becomes completely undetectable, vanishing from sight, sound, and smell. If the recipient is a creature carrying gear, that is similarly enchanted. Affected creatures remain undetected to all others, including the caster.

However, items dropped or put down by an undetectable creature become visible, give off sounds or smells again. Also, items picked up do not become undetectable if tucked into the clothing or pouches worn by the creature. The exception is placing items into a bag of holding or other item that makes them undetectable for reasons other than the spell.

Walking into a wall or otherwise making a sound, smell, or visual change to the environment outside of normal footprints or breathing produce noises, smells, and sights which are detectable. Attacking or casting a spell does not make the creature detectable, though it can make noises that seem to emanate from the location of the creature. It is wise for creatures affected by undetectability to either keep moving or to simply stand still for the duration of the spell.

As such, as long as the undetectable creature does not attack, cast a spell, or otherwise interact vigorously with it's environment, this spell prevents detection not only from normal sight, but also blindsight, blindsense, tremorsense, echolocation, scent and any other senses that rely on sight, sound, smell, or tactile vibration.

Spells which require the creature to be targeted by the caster cannot affect an undetectable creature. Undetectability cannot be detected by detect magic.

Undetectability can be made permanent (on objects only) with a permanency spell.
