|Introducing the Achievement System, a staple feature in more recent online games that presents various types of challenges with a touch of Granado Espada's sadistic gamepley style. It involves various measures of a player's game competency where a player has to achieve various condition and rewarded a relatively related rewards. The system is completely optional and doesn't affect the gameplay of a player but appeal to those who like a challenge, bragging rights or those who simply doesn't have a life.
I seriously doubt if the developers really think about the feasibilty of some achievements as it is very unrealistic. I guess their broken design of the roulette rewards spilled over this mess of an achievement system. I'm starting to think all competent developers have been assigned to Tree of Savior and left the incompetent ones to continue on Granado Espada updates.
Unfortunately, my data is heavily lacking but will be updated from time to time. I have grayed out unconfirmed information which are based only on estimates. Only one piece of the reward is given unless the quantity specified.
