Cursed Table (3.5e Equipment)
From D&D Wiki
The Cursed table was thought up when someone asked if he could take the table from a hut a quest had finish in. The DM's response was that the table was cursed and would slowly turn you into a chair. So here it is.
Upon being removed from anyone's possession (includes being given away) the table's effect activates. Over two weeks, who ever is in possession of this table slowly transforms into a chair, in addition to this they are not aware of this transformation. The previous owner transforms back when they no longer own the table. The transformation back takes the same amount of time that owner had the table.
