No published effect. This page does not guess at one.
The ice pick is one of five items players single out as unexplained. No published source describes an effect, and this page does not invent one.
Where this comes from
Listed on r/TheHalloweenGame among items with "no explanation for their use", alongside the brass lantern, hourglass, fuse and road flare.
How to read this
Every item page on this site carries one of three states, and they mean different things. Confirmed means a specific, actionable effect is documented or agreed on by players who tested it. Theorised means a hypothesis exists and the people offering it say it is unproven. No published effect means the item exists and is findable and nobody has published what it does — which is a real answer to a real question, and the one most likely to be dressed up as something else elsewhere.
