Immovable Rod

A round cylinder, made of strong metal. When activated by command word, it freezes in place,
even defying gravity. The rod can hold up to
8,000 pounds of weight, any more causing the
rod to deactivate and fall. A creature can use an
action to make a DC 30 Strength check, moving
the fixed rod up to 10 feet on a success. Upon
grabbing the rod and using the command word
it returns to normal.
SHAZAM!!!
