Combined observation: The mouthpiece can observe events

Combined observation: The mouthpiece can observe events is a combined memory created in JasKra's chamber during Heart of Stone by combining Observation: Transition and Observation: Present. It has no use, and may be separated to retrieve the original memories. It has the longest item name in all of RuneScape at 55 characters, surpassing the previous longest item name, Goblin squad (level 5) (heavy) (defeated) (and other goblin squads).

Reviewing
Looking over the combined visions, you believe that you can prove that the mouthpiece is capable of observing different events throughout time. Though you've got nothing to suggest it could observe the future.
