Short answer
Current guide testing reports two practical uses: while carried, the Fragile Hourglass can reveal nearby escape items within about 10 meters; thrown near Michael, it is reported to slow him. The escape-item reveal is the clearer lead. Treat exact combat effects and any timer or ability manipulation as unconfirmed until repeated in the current build.
The 10-meter and slow-effect observations come from an independent item guide. A player discussion shows that the rare-item effects were still unclear at launch; this is not an official item manual.
What is safe to say
Best way to test the hourglass
- Start with a known escape.Note the distance between your civilian and the escape item before picking up the hourglass.
- Carry, then compare.Check whether the item becomes easier to identify while you are within the reported radius.
- Separate the throw test.Do not mix the escape-finding observation with the claim that Michael is slowed.
- Record the patch and platform.Rare-item behavior is exactly the kind of detail that can change without a headline patch note.
Hourglass FAQ
Does the hourglass increase the match timer?
Not verified. The current public guide says it could not confirm timer or ability-cooldown manipulation, so this page does not claim it.
Is the hourglass the item that reveals Shape Jump Michael?
Be careful: the Lantern is the item associated with revealing Michael during Shape Jump in current guides. Do not merge the Lantern and Hourglass answers.
Should I keep the hourglass or drop it?
Keep it when your team still needs to locate an escape and you can test the reported radius. If you need a confirmed defensive effect, do not treat the hourglass as a guaranteed substitute for the Ancient Amulet.
