Any idea what this is worth?

As you sing, you feel a faint resonating vibration from the inset platinum bracelet in your hand...

The magical strength of this item is strong. It could probably handle the imbedding of an entirely new spell, if handled with care.
The bracelet resonates with your voice, indicating that it enhances its owner in the following ways:
It provides a boost of 3 to Arcane Symbols Bonus.
This enhancement may not be used by adventurers who have not trained 8 times.
It provides a boost of 2 to Spell Aiming Bonus.
This enhancement may not be used by adventurers who have not trained 3 times.
The bracelet looks to have more than your average giantman could count charges remaining.

You sense that the inset platinum bracelet will persist after its last enhancive charge has been expended.
