Invisibility will cause the targeted creature to vanish from normal and infrared sight.
This spell causes the creature touched to vanish from sight and be undetectable by normal vision or even infravision. Of course, the invisible creature is not magically silenced, and certain other conditions can render the creature detectable. Even allies cannot see the invisible creature or its gear, unless these allies can normally see invisible things or employ magic to do so. Items dropped or put down by the invisible creature become visible; items picked up disappear if tucked into the clothing or pouches worn by the creature. The spell remains in effect until it is magically broken or dispelled, until the recipient attacks a creature, or until 24 hours have passed. The caster cannot perform any actions that manipulate the environment around him, such as opening doors, disarming a trap, or opening a chest. The caster can, however, cast defensive spells on himself and fellow party members. And if he attacks, he immediately becomes visible, although the invisibility enables him to attack first.
