A sea-burnished ration cup with a lip spout and fine measure lines on the inside.

How It Works
Fill the cup with any liquid to the desired amount. Tap the cup’s base three times on a hard surface.
- Success: The holder feels a subtle tactile click from the handle. That volume is now the cup’s Active Measure for the day.
- Effect: For the rest of the day, any liquid poured from the cup will stop in a clean, dripless stream at the exact Active Measure. No more, no less.
Reset & Limits
- Reset: The cup resets at the next dawn.
- Early Reset: It can be reset early by being rinsed thoroughly and left completely dry for 1 hour.
- Limits: The cup does not heat, cool, purify, or create liquid. Spilling liquid from the cup does not “save” or extend the measured pour.
