Bracelets

Bracelets fill two additional slots in a character's equipment. Once you acquire a bracelet Aislinn can add one or more gems to it based on type of bracelet and what gems it can accept. Once gems are added, the bracelet becomes bound to the character. The effect of the bracelet is determined by gem(s) added. Each gem type boosts one stat a lot and others at random.
 * Diamond: ATK
 * Sapphire: M.ATK
 * Emerald: DEF
 * Ruby: HP

Gems also can be replaced by gems of the same color. If the original gem is undesired, the player can use another gem to replace it. The game will let the player know the changes to every stat that will take place, and the player will have the choice to confirm or refuse the replacement gem.

Gems can be obtained by completing the Succubus Queen or Revived Blood Lord raid(and any other Niflheim raids?). Bosses will drop key fragments which can be then brought to the General Store to be traded for a gem box. Bracelets can be obtained through a Masterpiece Bracelet Box, which is dropped in Hard and Hero daily raids for Season 1 and 70-80 raids and missions for Season 2.
