TWEAK

When an object is placed on a mob or in a room, the object is run through
code that scrambles, or tweaks, its stats. An item can get better than its
"base" stats, or it can get worse. Tweaking does not change any of your
current equipment. It does change items you will find in ZONES and on
MOBS

All equipment should not be the same. Everyone should not wear the same
stuff. That's why items tweak. This makes killing mobs much more fun,
because you never know what you'll get. Most things will not change much,
because it is an exponential scale. Extremely high or low stats are far
less likely to appear than stats close to the base. These are called
"freak tweaks" by players.

Meanwhile, having all objects slightly different AND having the chance
of finding something incredible on the most common of mobs is great!
