I _think_ this is the final version of my submission.
Non-rapier of Wooing
At rest, this item looks like a fine steel rapier. When gripped by the hilt, however, the blade glows almost imperceptibly, providing a flattering sidelight to its wielder (+2 enhancement bonus to Charisma, -20 penalty on Hide checks). When swung, the blade leaves a faint, pleasant scent of jasmine in its wake.
Three times per day, its wielder may perform the Deflect Arrows, Precise Shot, or Persuasive feats, even without their respective prerequisites. Performance of these feats requires an audience of at least one seeing creature with an Intelligence of 3 or higher. The audience must be within 30 feet of the wielder, and must be aware of the wielder's presence.
The "blade" is actually a dull, pliant material, incapable of drawing blood. Struck opponents take no damage, and must make a Sense Motive check or feel compelled to giggle at the ticklish sensation. After the item's three feats are used up, the wielded blade falls limp from ricasso to point--behaving more like leather rope than steel--until it's either released or ready to help its wielder impress a new audience tomorrow.
Moderate transmutation; CL 3rd; Craft Wondrous Item, 3rd-level bard; Price 1,800 gp.
