It may look like you’re at a disadvantage, but you can hold a battalion at bay with a broken chair and a mead jug.
Prerequisite: Catch Off-Guard
Benefit: Foes (even armed foes) are flat-footed against attacks you make with an improvised weapon. At the end of each round as a free action, a foe may make a Sense Motive check opposed by your Bluff check. If the foe’s Sense Motive check is successful, it stops being flat-footed by any improvised weapon attack you make for 24 hours. Your improvised weapon attacks threaten on a natural attack roll of 19 or 20.
