I don't think anyone has taken a look recently
I briefly looked at the code some time ago..but, I'm not sure how we're going to handle them with the existing data.
I'm pretty sure we'll need all of stats for the items across the levels..some add stats, some add augment slots, some add speech...
I haven't seen anything in peq..or 13th floor/Lucy to indicate multiple entries..though, everything but item speech 'may' be in the item history.
Someone else was talking about evolving items not too long ago..maybe we can get them to look at it again
