Power Bestowal (objects) – The ability to create objects of great power and/or objects that bestow power.
The second most powerful object in the Marvel universe is a Cosmic Cube.
One of the weirder objects that could bestow a different set of power each time is the Dial H for Hero dial (DC Who’s Who V1 #6).
In Fantastic Four V1 #57, the Silver Surfer creates a great weapon for Doctor Doom but this is a one-shot power for the Silver Surfer.
