Illusive Gnome Bewilderment (Combat)Source Weapon Master's Handbook pg. 12
You can use your gnome weapons in unusual ways.
Prerequisites: Int 13, Combat Expertise, Gnome Weapon FocusARG, Illusive Gnome Style, Illusive Gnome Surprise, Improved Feint, gnome magic and weapon familiarity racial traits.
Benefit: While using Illusive Gnome Style, when you successfully use Bluff to feint against an opponent, you can pick one special weapon feature from among those listed by Illusive Gnome Surprise and deny the opponent its Dexterity modifier to AC, as normal for feinting; alternatively, you can pick two special weapon features instead of one.
