Normal: By delivering an utterance of perception and analysis incorporating the truename of the object, you can determine a great deal about it.

The utterance determines all spells and magic properties of a single item, including how to activate those functions (if appropriate), and how many charges are left (if any).

Reverse: The item's properties become unclear and are shielded from revelation.

The touched object and its wearer gain a +10 bonus to saves against divination spells.
