Occasionally, you may see objects that are marked as being WELL_CRAFTED
or MASTERCRAFT.  These objects are said to be of higher quality and are
often more powerful than others, and can take greater enchantments than
normal objects.  Changing high quality items, for example by reforging or
carving on them, can sometimes improve them dramatically.

Players with sufficient skill in any of the various crafting skills can
produce higher quality items, even mastercraft ones. Using materials that
are more difficult to work with also has a higher chance of producing
mastercraft items. For example, you would be much more likely to
forge a mastercraft item from adamantium than from copper. Sleeping
until you are sharp will raise your chances of creating items of
mastercraft quality.

The tiers of quality in order of worst to best are:

WELL_CRAFTED
EXPERTLY_CRAFTED
MASTERCRAFT
MASTERCRAFT 2
MASTERCRAFT 3

You can increase the quality of a crafted item using the 'craft improve'
command. You must be equal or higher level than the item to be improved
and know the craft skill necessary to make it. It costs gold and
profession points to improve the quality of a crafted item.
