I beat you with a beer mug!

Ok, so I thought it might be fun to have my Altherian idiot walk around with a small shield and a beer mug as his primary weapon combo. Of course the “Beer Mug” is not on the weapon table it would therefore be an improvised weapon. So, what is the speed and damage of an improvised weapon? Is it reasonable to assume that a club is the closest thing? Also, should I assume that the beer mug does not come with any weapon tricks (unless later gained from the grand master path and applied to the beer mug that way)?

For those following my threads, I would note that I did notice that to use this combo effectively I have to have Tools of the Trade. That requires Weapon Savant. Which in turn requires Combat Aptitude (an a In 5 Lo 5 entry fee to play). So the feeble attribute : logic is right out. As such I’m switching his flaw to Mentally Weak to keep things as close as possible to original RP concept.
