You can use anything as a weapon.

Prerequisite: Catch Off-Guard, Throw Anything

Benefit: Gain proficiency in improvised weapons. In addition, gain a +1 bonus on all attack rolls with improvised weapons.

Special: This ability counts as having the Weapon Focus feat for purposes of meeting feat prerequisites.

Normal: A character with Catch Off-Guard and Throw Anything simply ignores penalties for using improvised weapons instead of gaining proficiency in them.
