Duration
Until dispelled or an attack is made

The object of this spell, whether a person or a thing, becomes invisible to both normal vision and to darkvision. If the Referee is using the invisibility rules unchanged, the result is that an invisible creature cannot be attacked unless its approximate location is known, and all attacks are made at -4 to-hit.
