a root-marked cardinal red orb

The orb resonates with your voice, indicating that it enhances its owner in the following ways:
It provides a boost of 10 to Constitution Base.
This enhancement may not be used by adventurers who have not trained 33 times.
This enhancive item has restrictions whose type are unclear to you.
The orb seems to be out of charges.
The bonuses provided by this item should last a very long time.

You sense that the cardinal red orb will persist after its last enhancive charge has been expended.
