Improved Deception +17: This item makes your weapons hard to focus upon and thus provides a +17 Competence bonus to Bluff checks. In addition, while using this item your weapons have a chance to envelop the target in darkness, making them vulnerable to Sneak Attacks for a short time.
Deadly +7: +7 Competence bonus to Weapon Damage.
Quality Bluff +4: +4 Quality bonus to Bluff.
Freedom of Movement: This item grants its wearer the ability to move and attack normally while under the influence of magic that impedes movement, such as paralysis, solid fog, slow and web.
This looks as if it used to be a really nice ring. Something clearly changed.
