Enhancments:  Enhancing your items is done on your research section.  Click on it and loot to the top left tab.  Throughout the day the percentage rate increases and decreases every 30 minutes.  Depending on your time zone in the world is when 95% enhance success rate comes around. It last 30 minutes twice a day.  Some people only do it during 95% time because of the odds.  I personal roll the dice and do it throughout the day.  Sometimes I try it as low as 25%.  But mainly I start doing it when it is 50% or above.  The higher you enhance your items the more expensive it gets to enhance more.  So when I get to the expensive upgrades I hold off until 95% rolls around.  Now you can enhance an item as high as the level of your research acadamy.  So if your research is level 23 you can enhance your items to level 23 and so on.  The higher you enhance your items the stonger your items are.  I try to fully enhance about 3 to 4 sets of items.  4 Weapons, 4 Books, 4 Mounts, and 4 Rings.  With the Mounts and Books I try to mix them up.  Get a conqueror and a Flake and get them both fully upgraded.  So depending on what kind of attack you plan on doing you have one of each at your disposal.  Same with the books.  Get a couple of defensive books and a couple of wisdom books. This is an extremely important part to looting in battle.  The enhancements get expensive but upgrading just a little more than the next guy can get you that extra you need to win the loot instead of lose or tie it.
