Monarch's Globe

A blood-red globe, decorated with a golden shell. Only those of royalty are worthy of calling this item their property.
Upon touching the globe, a creature may make a check with any ability of their choice as a way of proving they are worthy of drawing power from the orb. The DC for this check is 10. On a success, the creature may regain one charge of a class feature or racial trait or a number of spell slots totaling its proficiency bonus. On a fail, the creature takes Force damage equal to one roll of their hit die plus their proficiency bonus; this damage cannot be reduced in any way. Attempting to channel power from the orb will consume one charge, regardless of whether the check was a success or failure.
The globe may hold up to 3 charges. It regains 1d4-1 charges at the start of the day as long as it's been stowed away in a secure location.
Upon failing this check, the last creature that the globe regarded as its owner will become aware of the attempt and know the location of the orb and who failed to use it. A creature can only become the owner of the orb if it is recognized as a royal in any sense of the word, has successfully drawn power from the orb, and desires the orb to be its property.
