Oh this is where the title goes?
I would say you can treat a sword as an improvised weapon if you want, but then it will only do 1d4 damage. (And I don't think I would allow magic weapon abilities to apply.)While a DM is free to rule a Table Leg is similar enough to merit the damage die of a Greatclub, that's not quite the same a a DM saying a +1 Longsword counts as an Improvised weapon, don't you think?
