Here's a random obj stat changing routine I promised in my post. It
changes the stats randomly for the object.  Right now it's hard coded for
one specific item but can easily be adapted to allow different items and
different value limits.

Call it from update_objects() with whatever frequency you want.

something like "if(GET_VNUM(obj) == [obj you want randomized]) random_wpn(obj);"

In the structure, location is the stat to change, max & min are the
limits. Only one value is allowed to be negative at any time, and only one
value can be max'ed. (This requires xapobjs at the moment.) The inital
applies on the object are totally disregarded.


Thanks to Gehn at velgarian for the idea.
