You can turn nearly any object into a deadly weapon, from a razor-sharp chair leg to a sack of flour.
Benefit: You do not suffer any penalties for using an improvised weapon. Increase the amount of damage dealt by the improvised weapon by one step (for example, 1d4 becomes 1d6) to a maximum of 1d8 (2d6 if the improvised weapon is two-handed). The improvised weapon has a critical threat range of 19–20, with a critical multiplier of ×2.
